Hi Alex, thanks a lot for your reply. This sounds interesting. I'm using a prebuilt version deployed via cephadm, it's using some containers pulled from quay.io. Right now, I'm too scared to build his myself for the production system... Thinking about setting up a VM which mounts the cephfs via mount.ceph and exports it via regular NFS as a workaround... (Can't directly use mount.ceph due to old kernel verisons on some clients.)

On the NFS-side, I noticed missing files. There were no errors in the logfiles whatsoever. Solution was to rebuild nfs-ganesha with the most recent libceph-dev at that time. Are you using pre-built ganesha binaries or did you compile it yourself? Best Regards, Alex Walender Am 15.03.23 um 12:02 schrieb Patrick Schlangen:
Hi,
today I saw a strange situation where files which were copied to a cephfs via Ganesha NFS (deployed via cephadm) disappeared from the NFS directory and then did not show up anymore until I restarted the ganesha instance. This could be observed on different NFS client hosts. While the files were not showing, they could still be seen via cephfs-shell, so I assume the issue is somewhere on the NFS side. Interestingly, the folder modification time (shown in ls) matched the time the file was copied to that folder.
Any idea what could be the issue here? Unfortunately there were no interesting logs and I couldn't find a way yet to reproduce this.
The ceph version in use is 17.2.5.
Thanks,
