Fixed In Version: ceph-16.2.10-203.el8cp
Doc Type: Bug Fix
Doc Text:
.Creation of pool-level snaps for pools actively associated with a filesystem is disallowed Previously, the `ceph osd pool mksnap` command allowed the creation of pool-level snaps for pools actively associated with a filesystem. Due to this, there would be possible data loss when snapshots were deleted from either the filesystem or the pool due to pool ID collision. With this fix, creation of pool-level snaps for pools actively associated with a filesystem is disallowed and no data loss occurs.

Description Milind Changire 2023-05-15 07:26:10 UTC
+++ This bug was initially created as a clone of Bug #2189787 +++

Description of problem:
-----------------------
While verifying BZ - https://bugzilla.redhat.com/show_bug.cgi?id=2168541 found out that there are 2 ways to create a snap on rados pools, the fix was provided when "rados mksnap" is used, with "ceph osd pool mksnap" , it still allows to create a snap on the pool part of any existing file

Version-Release number of selected component (if applicable):
----------
ceph version 17.2.6-25.el9cp

How reproducible:
----------------
Always


Steps :
-------
[root@magna021 ~]# ceph fs ls
name: cephfs, metadata pool: cephfs.cephfs.meta, data pools: [cephfs.cephfs.data ]
name: newfs, metadata pool: cephfs.newfs.meta, data pools: [cephfs.newfs.data ]

[root@magna021 ~]# ceph osd lspools
1 .mgr
2 cephfs.cephfs.meta
3 cephfs.cephfs.data
4 .nfs
5 cephfs.newfs.meta
6 cephfs.newfs.data

[root@magna021 ~]# ceph osd pool mksnap cephfs.newfs.meta snap1
created pool cephfs.newfs.meta snap snap1

[root@magna021 ~]# ceph osd pool mksnap cephfs.newfs.data snap2
created pool cephfs.newfs.data snap snap2

[root@magna021 ~]# rados lssnap -p cephfs.newfs.meta
1       snap1   2023.04.24 19:04:39
1 snaps

[root@magna021 ~]# rados lssnap -p cephfs.newfs.data
1       snap2   2023.04.24 19:04:47
1 snaps
