No explanation, but chiming in, as I've seen something similar happen on my single node "cluster" at home, where I'm exposing a cephfs through Samba using vfs_ceph, mostly for time machine backups. Running ceph 14.2.6 on debian buster. I can easily perform debugging operations there, no SLA in place :) Jasper _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
