Version-Release number of selected component (if applicable): 4.5.16 How reproducible: Always Steps to Reproduce: 1. Take a cluster-backup using cluster-backup.sh on one master. 2. Copy the backup on to another master. 3. Attempt to restore the database on the other master using procedure documented. Actual results: The etcds fail to come up on all masters. Expected results: All etcds successfully start on all masters and the cluster recovers. Additional info: --- Additional comment from Suresh Kolichala on 2020-11-06 20:40:14 UTC --- As a workaround, a backup should be restored on the same master it is taken from. To determine the master where the backup is taken from, one may run the following command against the backup directory: sudo tar xvzf <backup>/static_kuberesources_*.tar.gz *restore-etcd-pod/pod.yaml --to-stdout 2>&1 | grep 'ETCD_NAME='
Tried with 4.4.0-0.ci.test-2020-12-23-042527-ci-ln-cs764w2 got backup from master-0, then restore with this backup on master-2, it succeed. # oc get pods -n openshift-etcd | grep etcd etcd-ip-10-0-139-137.us-east-2.compute.internal 4/4 Running 0 3m34s etcd-ip-10-0-168-222.us-east-2.compute.internal 4/4 Running 0 2m33s etcd-ip-10-0-205-133.us-east-2.compute.internal 4/4 Running 0 3m3s
