[jira] [Updated] (HDDS-4908) Layout version should be available in
DB for an un-finalized OM to be finalized through a Ratis snapshot.
[ https://issues.apache.org/jira/browse/HDDS-4908?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Aravindan Vijayan updated HDDS-4908:
------------------------------------
Description: Although OM Finalization is a Ratis request, it updates a persistent location outside the OM state machine maintained "RocksDB". Hence, in a rare case where an unfinalized OM needs a Ratis snapshot to finalize (without any logs), the VERSION file will not be updated, and hence the OM will be stuck in that state.
