Hi! I noticed the same that the snapshot scheduler seemed to do nothing , but after a manager fail over the creation of snapshots started to work (including the retention rules)..

Hi Team, *Problem:* Create scheduled snapshots of the ceph subvolume. *Expected Result:* The scheduled snapshots should be created at the given scheduled time. *Actual Result:* The scheduled snapshots are not getting created till we create a manual backup. *Description:* *Ceph version: 17(quincy)* OS: Centos/Almalinux The scheduled snapshot creation is not working and we were only able to see the following logs in the file "ceph-mgr.storagenode3.log": *2023-05-29T04:59:35.101+0000 7f4cd3ad8700 0 [snap_schedule INFO mgr_util] scanning for idle connections..* *2023-05-29T04:59:35.101+0000 7f4cd3ad8700 0 [snap_schedule DEBUG mgr_util] fs_name (cephfs) connections ([])* *2023-05-29T04:59:35.101+0000 7f4cd3ad8700 0 [snap_schedule INFO mgr_util] cleaning up connections: [* The command which we were executing to add the snapshot schedule: *ceph fs snap-schedule add /volumes/<subvolume_group>/<subvolume> <frequency_of_snapshot> <Timeinformat_yyyymmddTHH:MM:ss>* *eg.* *ceph fs snap-schedule add /volumes/xyz/test_restore_53 1h 2023-05-26T11:05:00* We can make sure that the schedule has been created using the following commands: *#ceph fs snap-schedule list / --recursive=true* *#ceph fs snap-schedule status /volumes/xyz/test_restore_53* Even though we created the snapshot schedule, snapshots were not getting created. We then tried creating a manual snapshot for one of the sub-volumes using the following command: *#ceph fs subvolume snapshot create cephfs <subvolume> <snapshot-name> --group_name <subvolume_group>* *eg. ceph fs subvolume snapshot create cephfs test_restore_53 snapshot-1 --group_name xyz* To check the snapshots created we can use the following command: *ceph fs subvolume snapshot ls cephfs <subvolume> <snapshot-name> <subvolume_group>* *eg. ceph fs subvolume snapshot ls cephfs test_restore_53 snapshot-1 xyz* To delete the manually created snapshot: *ceph fs subvolume snapshot rm cephfs <subvolume> <snapshot-name> <subvolume_group>* *eg. ceph fs subvolume snapshot rm cephfs test_restore_53 snapshot-1 xyz* To our surprise, the scheduled snapshots started working. We also applied the retention policy and seems to be working fine. We re-tested this understanding for another subvolume. And the scheduled snapshots only started once we triggered a manual snapshot. Could you please help us out with this? -- ~ Lokendra skype: lokendrarathour _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
