Description aarsharm 2025-03-24 10:09:28 UTC

Description of problem:
On running "rbd mirror group demote --pool pool_1 --group group_1"
Consistency group is demoted in addition with below error string.

"2025-03-24T09:23:03.559+0000 7fe7fa4db640 -1 librbd::mirror::snapshot::GroupUnlinkPeerRequest: 0x557f20c810b0 handle_remove_group_snapshot: failed to remove image snapshot metadata: (30) Read-only file system"

Above error string gives an impression to the user that something has gone wrong/bad. but the group is demoted successfully, so raising this bz to analyze and remove this error string from the output display. 

Version-Release number of selected component (if applicable):
[ceph: root@ceph-rbd1-cg-ds-tf74dn-node1-installer /]# ceph version
ceph version 19.2.1-57.el9cp (25ca432e5c2874ac833d0f13057a1b7d98913317) squid (stable)

rbd: error promoting group to primary
2025-03-24T09:22:47.266+0000 7f1b0bd53200 -1 librbd::api::Mirror: group_promote: group group_1 is already primary

2. demote a consietnct group on site-a/cluster1
[ceph: root@ceph-rbd1-cg-ds-tf74dn-node1-installer /]# rbd mirror group demote --pool pool_1 --group group_1
2025-03-24T09:23:03.559+0000 7fe7fa4db640 -1 librbd::mirror::snapshot::GroupUnlinkPeerRequest: 0x557f20c810b0 handle_remove_group_snapshot: failed to remove image snapshot metadata: (30) Read-only file system
