tudordumitriu opened a new issue #3124: URL: https://github.com/apache/couchdb/issues/3124
[NOTE]: # ( ^^ Provide a general summary of the issue in the title above. ^^ ) ## Description We have a kubernetes couchdb 3 nodes cluster deployed into azure aks. There are around 10 dbs with an average of 100 docs per database After deploying a fresh cluster using the existing databases (using the standard docker image https://github.com/apache/couchdb-docker) 3.1.0 and re-initializing the cluster (attached file couch.cluster.config.sh) after few minutes of usage from various services / clients we are getting the "No DB shards could be opened" error. General mentions: On a local dev k8s cluster the same setup works perfectly (same images/process) We did try some of the settings suggested in https://github.com/apache/couchdb/issues/796 (except the last one /etc/systemd/system/couchdb.d/override.conf but in a built docker couch image is harder to do that and checked the ulimit -n and seems pretty high) We are overriding local.ini on prestart with the attached file [local.ini.txt](https://github.com/apache/couchdb/files/5160180/local.ini.txt) Judging from the couch cluster error logs doesn't seem to be a resource problem but a auth issue (the logs are attached) The general k8s cluster CPU seems high but not used by the couch machines ## Steps to Reproduce Deploy new k8s cluster in azure aks Configure the cluster using script Generic API query / Fauxton admin usage (that crashes too with Database unavailable but after refresh appears ok which leads to the fact that the cluster nodes were not synced properly I think) ## Expected Behaviour - [NOTE]: # ( Tell us what you expected to happen. ) ## Your Environment Azure AKS 3 nodes cluster [TIP]: # ( Include as many relevant details about your environment as possible. ) [TIP]: # ( You can paste the output of curl http://YOUR-COUCHDB:5984/ here. ) * CouchDB version used: 3.1.0 * Browser name and version: Not relevant * Operating system and version: Azure ## Additional Context (logs, scripts and config files) [couch2.log](https://github.com/apache/couchdb/files/5160175/couch2.log) [couch0.log](https://github.com/apache/couchdb/files/5160176/couch0.log) [couch1.log](https://github.com/apache/couchdb/files/5160177/couch1.log) [local.ini.txt](https://github.com/apache/couchdb/files/5160184/local.ini.txt) [couch.cluster.config.sh.txt](https://github.com/apache/couchdb/files/5160172/couch.cluster.config.sh.txt) [TIP]: # ( Add any other context about the problem here. ) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
