## 2020-12-01
- Atmire responded about the issue with duplicate data in our Solr statistics
- They noticed that some records in the statistics-2015 core haven't been migrated with the AtomicStatisticsUpdateCLI tool yet and assumed that I haven't migrated any of the records yet
- That's strange, as I checked all ten cores and 2015 is the only one with some unmigrated documents, as according to the `cua_version` field
- I started processing those (about 411,000 records):
<!--more-->
```console
$ chrt -b 0 dspace dsrun com.atmire.statistics.util.update.atomic.AtomicStatisticsUpdateCLI -t 12 -c statistics-2015
```
- AReS went down when the `renew-letsencrypt` service stopped the `angular_nginx` container in the pre-update hook and failed to bring it back up
- I ran all system updates on the host and rebooted it and AReS came back up OK
## 2020-12-02
- Udana emailed me yesterday to ask why the CGSpace usage statistics were showing "No Data"
- I noticed a message in the Solr Admin UI that one of the statistics cores failed to load, but it is up and I can query it...
- Nevertheless, I restarted Tomcat a few times to see if all cores would come up without an error message, but had no success (despite that all cores ARE up and I can query them, _sigh_)
- I think I will move all the Solr yearly statistics back into the main statistics core
- Start testing export/import of yearly Solr statistics data into the main statistics core on DSpace Test, for example:
```
$ ./run.sh -s http://localhost:8081/solr/statistics-2010 -a export -o statistics-2010.json -k uid
$ ./run.sh -s http://localhost:8081/solr/statistics -a import -o statistics-2010.json -k uid
$ curl -s "http://localhost:8081/solr/statistics-2010/update?softCommit=true" -H "Content-Type: text/xml" --data-binary "<delete><query>*:*</query></delete>"
```
- I deployed Tomcat 7.0.107 on DSpace Test (CGSpace is still Tomcat 7.0.104)
- I finished migrating all the statistics from the yearly shards back to the main core
## 2020-12-05
- I deleted all the yearly statistics shards and restarted Tomcat on DSpace Test (linode26)
## 2020-12-06
- Looking into the statistics on DSpace Test after I migrated them back to the main core
- All stats are working as expected... indexing time for the DSpace Statistics API is the same... and I don't even see a difference in the JVM or memory stats in Munin other than a minor jump last week when I was processing them
- I will migrate them on CGSpace too I think
- First I will start with the statistics-2010 and statistics-2015 cores because they were the ones that were failing to load recently (despite actually being available in Solr WTF)
![Error message in Solr admin UI about the statistics-2010 core failing to load](/cgspace-notes/2020/12/solr-statistics-2010-failed.png)
- First the 2010 core:
```console
$ chrt -b 0 ./run.sh -s http://localhost:8081/solr/statistics-2010 -a export -o statistics-2010.json -k uid
$ chrt -b 0 ./run.sh -s http://localhost:8081/solr/statistics -a import -o statistics-2010.json -k uid
$ curl -s "http://localhost:8081/solr/statistics-2010/update?softCommit=true" -H "Content-Type: text/xml" --data-binary "<delete><query>*:*</query></delete>"
```
- Judging by the DSpace logs all these cores had a problem starting up in the last month:
```console
# grep -rsI "Unable to create core" [dspace]/log/dspace.log.2020-* | grep -o -E "statistics-[0-9]+" | sort | uniq -c
24 statistics-2010
24 statistics-2015
18 statistics-2016
6 statistics-2018
```
- The message is always this:
```
org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException: Error CREATEing SolrCore 'statistics-2016': Unable to create core [statistics-2016] Caused by: Lock obtain timed out: NativeFSLock@/[dspace]/solr/statistics-2016/data/index/write.lock
```
- I will migrate all these cores and see if it makes a difference, then probably end up migrating all of them
- I removed the statistics-2010, statistics-2015, statistics-2016, and statistics-2018 cores and restarted Tomcat and _all the statistics cores came up OK and the CUA statistics are OK_!
## 2020-12-07
- Run `dspace cleanup -v` on CGSpace to clean up deleted bitstreams
- Atmire sent a [pull request](https://github.com/ilri/DSpace/pull/457) to address the duplicate owningComm and owningColl
- Built and deployed it on DSpace Test but I am not sure how to run it yet
- I sent feedback to Atmire on their tracker: https://tracker.atmire.com/tickets-cgiar-ilri/view-ticket?id=839
- Abenet and Tezira are having issues with committing to the archive in their workflow
- I looked at the server and indeed the locks and transactions are back up:
![PostgreSQL Transactions day](/cgspace-notes/2020/12/postgres_transactions_ALL-day.png)
![PostgreSQL Locks day](/cgspace-notes/2020/12/postgres_locks_ALL-day.png)
![PostgreSQL Locks day](/cgspace-notes/2020/12/postgres_querylength_ALL-day.png)
![PostgreSQL Connections day](/cgspace-notes/2020/12/postgres_connections_ALL-day.png)
- There are apparently 1,700 locks right now:
```console
$ psql -c 'SELECT * FROM pg_locks pl LEFT JOIN pg_stat_activity psa ON pl.pid = psa.pid;' | wc -l
1739
```
## 2020-12-08
- Atmire sent some instructions for using the DeduplicateValuesProcessor
- I modified `atmire-cua-update.xml` as they instructed, but I get a million errors like this when I run AtomicStatisticsUpdateCLI with that configuration:
```
Record uid: 64387815-d9a7-4605-8024-1c0a5c7520e0 couldn't be processed

```
- I sent some feedback to Atmire
- They responded with an updated CUA (6.x-4.1.10-ilri-RC7) that has a fix for the duplicates processor _and_ a possible fix for the database locking issues (a bug in CUASolrLoggerServiceImpl that causes an infinite loop and a Tomcat timeout)
- I deployed the changes on DSpace Test and CGSpace, hopefully it will fix both issues!
- In other news, after I restarted Tomcat on CGSpace the statistics-2013 core didn't come back up properly, so I exported it and imported it into the main statistics core like I did for the others a few days ago
- Sync DSpace Test with CGSpace's Solr, PostgreSQL database, and assetstore...
## 2020-12-09
- I was running the AtomicStatisticsUpdateCLI to remove duplicates on DSpace Test but it failed near the end of the statistics core (after 20 hours or so) with a memory error:
```

## 2020-12-10
- The statistics-2019 core finished processing the duplicate removal so I started the statistics-2017 core
- Peter asked me to add ONE HEALTH to ILRI subjects on CGSpace
- A few items that got "lost" after approval during the database issues earlier this week seem to have gone back into their workflows
- Abenet approved them again and they got new handles, phew
- Abenet was having an issue with the date filter on AReS and it turns out that it's the same `.keyword` issue I had noticed before that causes the filter to stop working
- I fixed the filter to use the correct field name and filed a bug on OpenRXV: https://github.com/ilri/OpenRXV/issues/63
- I checked the Solr statistics on DSpace Test to see if the Atmire duplicates remover was working, but now I see a comical amount of duplicates...
![Solr stats with dozens of duplicates](/cgspace-notes/2020/12/solr-stats-duplicates.png)
- I sent feedback about this to Atmire
- I will re-sync the Solr stats from CGSpace so we can try again...
- In other news, it has been a few days since we deployed the fix for the database locking issue and things seem much better now:
![PostgreSQL connections all week](/cgspace-notes/2020/12/postgres_connections_ALL-week.png)
![PostgreSQL locks all week](/cgspace-notes/2020/12/postgres_locks_ALL-week.png)
## 2020-12-13
- I tried to harvest a few times on OpenRXV in the last few days and every time it appends all the new records to the items index instead of overwriting it:
![OpenRXV duplicates](/cgspace-notes/2020/12/openrxv-duplicates.png)
- I can see it in the `openrxv-items-final` index:
```console
$ curl -s 'http://localhost:9200/openrxv-items-final/_count?q=*' | json_pp
{
"_shards" : {
"failed" : 0,
"skipped" : 0,
"successful" : 1,
"total" : 1
},
"count" : 299922
}
```
- I filed a bug on OpenRXV: https://github.com/ilri/OpenRXV/issues/64
- For now I will try to delete the index and start a re-harvest in the Admin UI:
```
$ curl -XDELETE http://localhost:9200/openrxv-items-final
{"acknowledged":true}%
```
- Moayad said he's working on the harvesting so I stopped it for now to re-deploy his latest changes
- I updated Tomcat to version 7.0.107 on CGSpace (linode18), ran all updates, and restarted the server
- I deleted both items indexes and restarted the harvesting:
```
$ curl -XDELETE http://localhost:9200/openrxv-items-final
$ curl -XDELETE http://localhost:9200/openrxv-items-temp
```
- Peter asked me for a list of all submitters and approvers that were active recently on CGSpace
- I can probably extract that from the `dc.description.provenance` field, for example any that contains a 2020 date:
```console
localhost/dspace63= > SELECT * FROM metadatavalue WHERE metadata_field_id=28 AND text_value ~ '^.*on 2020-[0-9]{2}-*';
```
## 2020-12-14
- The re-harvesting finished last night on AReS but there are no records in the `openrxv-items-final` index
- Strangely, there are 99,000 items in the temp index:
```console
$ curl -s 'http://localhost:9200/openrxv-items-temp/_count?q=*' | json_pp
{
"count" : 99992,
"_shards" : {
"skipped" : 0,
"total" : 1,
"failed" : 0,
"successful" : 1
}
}
```
- I'm going to try to [clone](https://www.elastic.co/guide/en/elasticsearch/reference/master/indices-clone-index.html) the temp index to the final one...
- First, set the `openrxv-items-temp` index to block writes (read only) and then clone it to `openrxv-items-final`:
```console
$ curl -X PUT "localhost:9200/openrxv-items-temp/_settings?pretty" -H 'Content-Type: application/json' -d'{"settings": {"index.blocks.write": true}}'
$ curl -s -X POST http://localhost:9200/openrxv-items-temp/_clone/openrxv-items-final
{"acknowledged":true,"shards_acknowledged":true,"index":"openrxv-items-final"}
$ curl -X PUT "localhost:9200/openrxv-items-temp/_settings?pretty" -H 'Content-Type: application/json' -d'{"settings": {"index.blocks.write": false}}'
```
- Now I see that the `openrxv-items-final` index has items, but there are still none in AReS Explorer UI!
```console
$ curl -s 'http://localhost:9200/openrxv-items-final/_count?q=*&pretty'
{
"count" : 99992,
"_shards" : {
"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
}
}
```
- The api logs show this from last night after the harvesting:
```console
[Nest] 92 - 12/13/2020, 1:58:52 PM [HarvesterService] Starting Harvest

at processTicksAndRejections (internal/process/task_queues.js:84:21)
```
- But I'm not sure why the frontend doesn't show any data despite there being documents in the index...
- I talked to Moayad and he reminded me that OpenRXV uses an alias to point to temp and final indexes, but the UI actually uses the `openrxv-items` index
- I cloned the `openrxv-items-final` index to `openrxv-items` index and now I see items in the explorer UI
- The PDF report was broken and I looked in the API logs and saw this:
```console
(node:94) UnhandledPromiseRejectionWarning: Error: Error: Could not find soffice binary
at ExportService.downloadFile (/backend/dist/export/services/export/export.service.js:51:19)
at processTicksAndRejections (internal/process/task_queues.js:97:5)
```
- I installed `unoconv` in the backend api container and now it works... but I wonder why this changed...
- Skype with Abenet and Peter to discuss AReS that will be shown to ILRI scientists this week
- Peter noticed that [this item](https://hdl.handle.net/10568/110133) from the [ILRI policy and research briefs](https://cgspace.cgiar.org/handle/10568/24450) collection is missing in AReS, despite it being added one month ago in CGSpace and me harvesting on AReS last night
- The item appears fine in the REST API when I check the items in that collection
- Peter also noticed that [this item](https://hdl.handle.net/10568/110447) appears twice in AReS
- The item is _not_ duplicated on CGSpace or in the REST API
- We noticed that there are 136 items in the ILRI policy and research briefs collection according to AReS, yet on CGSpace there are only 132
- This is confirmed in the REST API (using [query-json](https://github.com/davesnx/query-json)):
```
$ http --print b 'https://cgspace.cgiar.org/rest/collections/defee001-8cc8-4a6c-8ac8-21bb5adab2db?expand=all&limit=100&offset=0' | json_pp > /tmp/policy1.json
$ http --print b 'https://cgspace.cgiar.org/rest/collections/defee001-8cc8-4a6c-8ac8-21bb5adab2db?expand=all&limit=100&offset=100' | json_pp > /tmp/policy2.json
$ query-json '.items | length' /tmp/policy1.json
100
$ query-json '.items | length' /tmp/policy2.json
32
```
- I realized that the issue of missing/duplicate items in AReS might be because of this [REST API bug that causes /items to return items in non-deterministic order](https://jira.lyrasis.org/browse/DS-3849)
- I decided to cherry-pick the following two patches from DSpace 6.4 into our `6_x-prod` (6.3) branch:
- High CPU usage when calling the collection_id/items REST endpoint
- Jira: https://jira.lyrasis.org/browse/DS-4342
- c2e6719fa763e291b81b2d61da2f8c758fe38ff3
- REST API items resource returns items in non-deterministic order
- Jira: https://jira.lyrasis.org/browse/DS-3849
- 2a2ea0cb5d03e6da9355a2eff12aad667e465433
- After deploying the REST API fixes I decided to harvest from AReS again to see if the missing and duplicate items get fixed
- I made a backup of the current `openrxv-items-temp` index just in case:
```console
$ curl -X PUT "localhost:9200/openrxv-items-temp/_settings?pretty" -H 'Content-Type: application/json' -d'{"settings": {"index.blocks.write": true}}'
$ curl -s -X POST http://localhost:9200/openrxv-items-temp/_clone/openrxv-items-2020-12-14
$ curl -X PUT "localhost:9200/openrxv-items-temp/_settings?pretty" -H 'Content-Type: application/json' -d'{"settings": {"index.blocks.write": false}}'
```
## 2020-12-15
- After the re-harvest last night there were 200,000 items in the `openrxv-items-temp` index again
- I cleared the core and started a re-harvest, but Peter sent me a bunch of author corrections for CGSpace so I decided to cancel it until after I apply them and re-index Discovery
- I checked the 1,534 fixes in Open Refine (had to fix a few UTF-8 errors, as always from Peter's CSVs) and then applied them using the `fix-metadata-values.py` script:
```console
$ ./fix-metadata-values.py -i /tmp/2020-10-28-fix-1534-Authors.csv -db dspace -u dspace -p 'fuuu' -f dc.contributor.author -t 'correct' -m 3
$ ./delete-metadata-values.py -i /tmp/2020-10-28-delete-2-Authors.csv -db dspace -u dspace -p 'fuuu' -f dc.contributor.author -m 3
```
- Since I was re-indexing Discovery anyways I decided to check for any uppercase AGROVOC and lowercase them:
```console
dspace=# BEGIN;
BEGIN
dspace=# UPDATE metadatavalue SET text_value=LOWER(text_value) WHERE dspace_object_id IN (SELECT uuid FROM item) AND metadata_field_id=57 AND text_value ~ '[[:upper:]]';
UPDATE 406
dspace=# COMMIT;
COMMIT
```
- I also updated the Font Awesome icon classes for version 5 syntax:
```console
dspace=# BEGIN;
dspace=# UPDATE metadatavalue SET text_value = REGEXP_REPLACE(text_value, 'fa fa-rss','fas fa-rss', 'g') WHERE text_value LIKE '%fa fa-rss%';
UPDATE 74
dspace=# UPDATE metadatavalue SET text_value = REGEXP_REPLACE(text_value, 'fa fa-at','fas fa-at', 'g') WHERE text_value LIKE '%fa fa-at%';
UPDATE 74
dspace=# COMMIT;
```
- Then I started a full Discovery re-index:
```console
$ export JAVA_OPTS="-Dfile.encoding=UTF-8 -Xmx512m"
$ time chrt -b 0 ionice -c2 -n7 nice -n19 dspace index-discovery -b
real 265m11.224s
user 171m29.141s
sys 2m41.097s
```
- Udana sent a report that the WLE approver is experiencing the same issue Peter highlighted a few weeks ago: they are unable to save metadata edits in the workflow
- Yesterday Atmire responded about the owningComm and owningColl duplicates in Solr saying they didn't see any anymore...
- Indeed I spent a few minutes looking randomly and I didn't find any either...
- I did, however, see lots of duplicates in countryCode_search, countryCode_ngram, ip_search, ip_ngram, userAgent_search, userAgent_ngram, referrer_search, referrer_ngram fields
- I sent feedback to them
- On the database locking front we haven't had issues in over a week and the Munin graphs look normal:
![PostgreSQL connections all week](/cgspace-notes/2020/12/postgres_connections_ALL-week2.png)
![PostgreSQL locks all week](/cgspace-notes/2020/12/postgres_locks_ALL-week2.png)
- After the Discovery re-indexing finished on CGSpace I prepared to start re-harvesting AReS by making sure the `openrxv-items-temp` index was empty and that the backup index I made yesterday was still there:
```console
$ curl -XDELETE 'http://localhost:9200/openrxv-items-temp?pretty'
{
"acknowledged" : true
}
$ curl -s 'http://localhost:9200/openrxv-items-final/_count?q=*&pretty'
{
"count" : 0,
"_shards" : {
"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
}
}
$ curl -s 'http://localhost:9200/openrxv-items-2020-12-14/_count?q=*&pretty'
{
"count" : 99992,
"_shards" : {
"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
}
}
```
## 2020-12-16
- The harvesting on AReS finished last night so this morning I manually cloned the `openrxv-items-temp` index to `openrxv-items`
- First check the number of items in the temp index, then set it to read only, then delete the items index, then delete the temp index:
```console
$ curl -s 'http://localhost:9200/openrxv-items-temp/_count?q=*&pretty'
{
"count" : 100046,
"_shards" : {
"total" : 1,

- Interestingly [the item](https://hdl.handle.net/10568/110447) that we noticed was duplicated now only appears once
- The [missing item](https://hdl.handle.net/10568/110133) is still missing
- Jane Poole noticed that the "previous page" and "next page" buttons are not working on AReS
- I filed a bug on GitHub: https://github.com/ilri/OpenRXV/issues/65
- Generate a list of submitters and approvers active in the last months using the Provenance field on CGSpace:
```console
$ psql -h localhost -U postgres dspace -c "SELECT text_value FROM metadatavalue WHERE metadata_field_id=28 AND text_value ~ '^.*on 2020-(06|07|08|09|10|11|12)-*'" > /tmp/provenance.txt
$ grep -o -E 'by .*)' /tmp/provenance.txt | grep -v -E "( on |checksum)" | sed -e 's/by //' -e 's/ (/,/' -e 's/)//' | sort | uniq > /tmp/recent-submitters-approvers.csv
```
- Peter wanted it to send some mail to the users...
## 2020-12-17
- I see some errors from CUA in our Tomcat logs:
```console

```
- I sent the full stack to Atmire to investigate
- I know we've had this "Multiple update components target the same field" error in the past with DSpace 5.x and Atmire said it was harmless, but would nevertheless be fixed in a future update
- I was trying to export the ILRI community on CGSpace so I could update one of the ILRI author's names, but it throws an error...
```console
$ dspace metadata-export -i 10568/1 -f /tmp/2020-12-17-ILRI.csv

- I did it via CSV with `fix-metadata-values.py` instead:
```console

```
- Abenet needed a list of all 2020 outputs from the Livestock CRP that were Limited Access
- I exported the community from CGSpace and used `csvcut` and `csvgrep` to get a list:
```
$ csvcut -c 'dc.identifier.citation[en_US],dc.identifier.uri,dc.identifier.uri[],dc.identifier.uri[en_US],dc.date.issued,dc.date.issued[],dc.date.issued[en_US],cg.identifier.status[en_US]' ~/Downloads/10568-80099.csv | csvgrep -c 'cg.identifier.status[en_US]' -m 'Limited Access' | csvgrep -c 'dc.date.issued' -m 2020 -c 'dc.date.issued[]' -m 2020 -c 'dc.date.issued[en_US]' -m 2020 > /tmp/limited-2020.csv
```
## 2020-12-18
- I added support for indexing community views and downloads to [dspace-statistics-api](https://github.com/ilri/dspace-statistics-api)
- I still have to add the API endpoints to make the stats available
- Also, I played a little bit with Swagger via [falcon-swagger-ui](https://github.com/rdidyk/falcon-swagger-ui) and I think I can get that working for better API documentation / testing
- Atmire sent some feedback on the DeduplicateValuesProcessor
- They confirm that it should process _all_ duplicates, not just those in `owningComm` and `owningColl`
- They asked me to try it again on DSpace Test now that I've resync'd the Solr statistics cores from production
- I started processing the statistics core on DSpace Test
## 2020-12-20
- The DeduplicateValuesProcessor has been running on DSpace Test since two days ago and it almost completed its second twelve-hour run, but crashed near the end:
```console

```
- That was with a JVM heap of 512m
- I looked in Solr and found dozens of duplicates of each field again...
- I sent [feedback to Atmire](https://tracker.atmire.com/tickets-cgiar-ilri/view-ticket?id=839)
- I finished the technical work on adding community and collection support to the DSpace Statistics API
- I still need to update ~~the tests~~ as well as the documentation
- I started a harvesting of AReS
## 2020-12-21
- The AReS harvest finished this morning and I moved the Elasticsearch index manually
- First, check the number of records in the temp index to make sure it seems complete and not with double data:
```console
$ curl -s 'http://localhost:9200/openrxv-items-temp/_count?q=*&pretty'
{
"count" : 100135,
"_shards" : {
"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
}
}
```
- Then delete the old backup and clone the current items index as a backup:
```console
$ curl -XDELETE 'http://localhost:9200/openrxv-items-2020-12-14?pretty'
$ curl -X PUT "localhost:9200/openrxv-items/_settings?pretty" -H 'Content-Type: application/json' -d'{"settings": {"index.blocks.write": true}}'
$ curl -s -X POST http://localhost:9200/openrxv-items/_clone/openrxv-items-2020-12-21
```
- Then delete the current items index and clone it from temp:
```console
$ curl -XDELETE 'http://localhost:9200/openrxv-items?pretty'
$ curl -X PUT "localhost:9200/openrxv-items-temp/_settings?pretty" -H 'Content-Type: application/json' -d'{"settings": {"index.blocks.write": true}}'
$ curl -s -X POST http://localhost:9200/openrxv-items-temp/_clone/openrxv-items
$ curl -X PUT "localhost:9200/openrxv-items-temp/_settings?pretty" -H 'Content-Type: application/json' -d'{"settings": {"index.blocks.write": false}}'
```
## 2020-12-22
- I finished getting the Swagger UI integrated into the dspace-statistics-api
- I can't figure out how to get it to work on the server without hard-coding all the paths
- Falcon is smart about its own routes, so I can retrieve the `openapi.json` file OK, but the paths in the OpenAPI schema are relative to the base URL, which is `dspacetest.cgiar.org`
- Abenet told me about a bug with shared links and strange values in the top counters
- I took a video reproducing the issue and filed a bug on the GitHub: https://github.com/ilri/OpenRXV/issues/66
## 2020-12-23
- Finalize Swagger UI support in the dspace-statistics-api
- I had to do some last minute changes to get it to work in both production and local development environments
## 2020-12-27
- More finishing touches on paging and versioning of the dspace-statistics-api
- I tagged v1.4.0 and released it on GitHub: https://github.com/ilri/dspace-statistics-api/releases/tag/v1.4.0
- I deployed it on DSpace Test and CGSpace
## 2020-12-28
- Peter noticed that the Atmire CUA stats on CGSpace weren't working
- I looked in Solr Admin UI and saw that the statistics-2012 core failed to load:
```
statistics-2012: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Error opening new searcher
```
- I exported the 2012 stats from the year core and imported them to the main statistics core with solr-import-export-json:
```console
$ chrt -b 0 ./run.sh -s http://localhost:8081/solr/statistics-2012 -a export -o statistics-2012.json -k uid
$ chrt -b 0 ./run.sh -s http://localhost:8081/solr/statistics -a import -o statistics-2010.json -k uid
$ curl -s "http://localhost:8081/solr/statistics-2012/update?softCommit=true" -H "Content-Type: text/xml" --data-binary "<delete><query>*:*</query></delete>"
```
- I decided to do the same for the remaining 2011, 2014, 2017, and 2019 cores...
## 2020-12-29
- Start a fresh re-index on AReS, since it's been over a week since the last time
- Before then I cleared the old `openrxv-items-temp` index and made a backup of the current `openrxv-items` index:
```console
$ curl -s 'http://localhost:9200/openrxv-items/_count?q=*&pretty'
{
"count" : 100135,
"_shards" : {
"total" : 1,
"successful" : 1,
"skipped" : 0,
"failed" : 0
}
}
$ curl -XDELETE 'http://localhost:9200/openrxv-items-temp?pretty'
$ curl -X PUT "localhost:9200/openrxv-items/_settings?pretty" -H 'Content-Type: application/json' -d'{"settings": {"index.blocks.write": true}}'
$ curl -s -X POST http://localhost:9200/openrxv-items/_clone/openrxv-items-2020-12-29
$ curl -X PUT "localhost:9200/openrxv-items/_settings?pretty" -H 'Content-Type: application/json' -d'{"settings": {"index.blocks.write": false}}'
```
## 2020-12-30
- The indexing on AReS finished so I cloned the `openrxv-items-temp` index to `openrxv-items` and deleted the backup index:
```console
$ curl -XDELETE 'http://localhost:9200/openrxv-items?pretty'
$ curl -X PUT "localhost:9200/openrxv-items-temp/_settings?pretty" -H 'Content-Type: application/json' -d'{"settings": {"index.blocks.write": true}}'
$ curl -s -X POST http://localhost:9200/openrxv-items-temp/_clone/openrxv-items
$ curl -X PUT "localhost:9200/openrxv-items-temp/_settings?pretty" -H 'Content-Type: application/json' -d'{"settings": {"index.blocks.write": false}}'
$ curl -XDELETE 'http://localhost:9200/openrxv-items-temp?pretty'
$ curl -XDELETE 'http://localhost:9200/openrxv-items-2020-12-29?pretty'
```
