Thanks. This is the relevant line:
[pid 6448] mount("ceph-fuse", "/var/log/pve/tasks", 0x557e68f75cb0,
MS_MGC_VAL|MS_REMOUNT|MS_NOATIME, "nonempty") = 0
It's "mount -o remount -o unknownoption" that is broken. Fix is a
little complex, because we want the old behavior on the old mount(2)
api, but the new behavior on the fsconfig(2) api. Will post a patch
tomorrow.
Thanks,
Miklos
