And I don't see why would the admin socket get recreated each day. The mirror daemon does not do anything special with the admin sockets apart from registering some asok hooks (commands). Can you enable asok debugging with "debug asok = 20" and provide mirror daemon logs? Let the mirror daemon run for a day or two until you see the asok path change. Also run the mirror daemon with `--debug-cephfs_mirror = 20`. Update after discussing with Hemanth: logrotate seems to be backing up the log file and around the same time a new asok file is generated which is very weird. logrotate sends a SIGHUP to ceph daemons, however, the mirror daemon is not included in the daemon list (we probably need to add that). Hmeanth will check with the respective devs and update (Thanks, Hemanth!).
