Description

Assuming the following:

[root@rook-ceph-tools-78cdfd976c-xltx5 /]# ceph fs snap-schedule list / fs=myfs2 format=json
{"path": "/", "schedule": ["2d", "4d"], "retention": [{}, {}]}

Then removing the snapshot schedules:

[root@rook-ceph-tools-78cdfd976c-xltx5 /]# ceph fs snap-schedule remove / 4d fs=myfs2
Schedule removed for path /
[root@rook-ceph-tools-78cdfd976c-xltx5 /]# ceph fs snap-schedule remove / 2d 2014-01-09T21:48:00 fs=myfs2
Schedule removed for path /
[root@rook-ceph-tools-78cdfd976c-xltx5 /]# ceph fs snap-schedule list / fs=myfs2 format=json
{}

The status is also empty:

[root@rook-ceph-tools-78cdfd976c-xltx5 /]# ceph fs snap-schedule status / fs=myfs2 format=json
[]

Now reloading the module:

[root@rook-ceph-tools-78cdfd976c-xltx5 /]# ceph mgr module disable snap_schedule && ceph mgr module enable snap_schedule --force

And here they are again:

[root@rook-ceph-tools-78cdfd976c-xltx5 /]# ceph fs snap-schedule status / fs=myfs2 format=json
[{"fs": "myfs2", "subvol": null, "path": "/", "rel_path": "/", "schedule": "2d", "retention": {}, "start": "2014-01-09T21:48:00", "created": "2021-03-17T09:32:03", "first": null, "last": null, "last_pruned": null, "created_count": 0, "pruned_count": 0, "active": true},{"fs": "myfs2", "subvol": null, "path": "/", "rel_path": "/", "schedule": "4d", "retention": {}, "start": "2021-03-17T00:00:00", "created": "2021-03-17T09:30:57", "first": null, "last": null, "last_pruned": null, "created_count": 0, "pruned_count": 0, "active": true}]
[root@rook-ceph-tools-78cdfd976c-xltx5 /]# 
[root@rook-ceph-tools-78cdfd976c-xltx5 /]# 
[root@rook-ceph-tools-78cdfd976c-xltx5 /]# ceph fs snap-schedule list / fs=myfs2 format=json
{"path": "/", "schedule": ["2d", "4d"], "retention": [{}, {}]}
