Hi Alain, It seems to be related to this kernel bug: https://bugzilla.kernel.org/show_bug.cgi?id=220807 Upgrading your kernel should be a solution on Debian 13 (kernel 6.12.73-1 is OK) Arnaud Le 17/03/2026 23:07, « Alain Bertrand via ceph-users » <ceph-users@ceph.io <mailto:ceph-users@ceph.io>> a écrit : Hi. I'm new here. I have been playing with ceph for a few years (nothing dramatic, just using it in my proxmox cluster to store VM images and host a cephfs with a lot of shared files). I think I found a bug in the cephfs client in the Linux kernel. Listing snapshots (ls .snap) in a lot of directories quickly causes a kernel panic. I tried to create an account on the bug tracker at tracker.ceph.com a week ago, but still can't log in there. Do I put details here, or report somewhere else? What's the next step I should take?
