Ceph » CephFS

In https://tracker.ceph.com/issues/54052 the issue that scheduled snapshots are not longer created after a mgr restart was fixed. The fix is included in 16.2.8. After updating from 16.2.7 to 16.2.9 I noticed that indeed scheduled snapshots are still created after a mgr restart, however the snapshot retention policy is gone.

My snapshot schedule/retention policy is configured as follows:

# ceph mgr module enable snap_schedule
# ceph fs snap-schedule add /projects 1h
Schedule set for path /projects
# ceph fs snap-schedule retention add /projects 24h7d4w3m
Retention added to path /projects
# ceph fs snap-schedule list /projects
/projects 1h 24h7d4w3m

After the update and the corresponding mgr restart the renention policy is gone and snapshots are no longer pruned based on the policy:

# ceph fs snap-schedule list /projects
/projects 1h
