Enable disaster recovery features
The Bitnami etcd Helm chart supports automatic disaster recovery by periodically snapshotting the keyspace. If the cluster permanently loses more than (N-1)/2 members, it tries to recover the cluster from a previous snapshot.
Enable this feature with the following parameters:
persistence.enabled=true disasterRecovery.enabled=true disasterRecovery.pvc.size=2Gi disasterRecovery.pvc.storageClassName=nfs
If the startFromSnapshot.* parameters are used at the same time as the disasterRecovery.* parameters, the PVC provided via the startFromSnapshot.existingClaim parameter will be used to store the periodical snapshots.
NOTE: The disaster recovery feature requires volumes with ReadWriteMany access mode.
