Christopher Hoffman 2023-06-14 14:20:59 UTC Doc Text Cause: Remote cluster cannot grab lock quickly enough to remove synced snapshot while I/O is underway. This can be due to latency between sites.

Consequence: The mirror image snapshot sync process gets stuck on the removal snapshot step and does not continue with syncing further snapshots.

Fix: Move snapshot removal step to primary site which can grab lock fast enough to remove snapshot.

Result: The mirror image snapshot sync doesn't get stuck and continues as normal.

.Snapshot removal tep is moved to the primary site
Previously, a remote cluster could not grab lock quickly enough to remove synced snapshot while I/O was underway due to latency between sites. This would cause the mirror image snapshot sync process to be stuck during snapshot removal and would not continue with syncing further snapshots.

With this fix, the snapshot removal step is moved to the primary site which grabs the lock fast enough to remove the snapshot and the mirror image snapshot sync does not get stuck and works as expected.
