Description

Hi,

Running Proxmox 7.4-3 with Ceph version ceph version 17.2.6 (995dec2cdae920da21db2d455e55efbc339bde24) quincy (stable)
Kernel version Linux kvm-01 5.15.107-2-pve #1 SMP PVE 5.15.107-2 (2023-05-10T09:10Z) x86_64 GNU/Linux

I recently upgraded from 17.2.5 to 17.2.6.
Ever since when I try to create a RBD snapshot this fails with the following error:

# rbd snap create k8s_cephfs_data/csi-vol-8f127c1e-5dc8-4b9a-acc5-7f28eefd1ed0@test123
