I'm trying to eliminate disk read/writes (as much as possible). Winbind is one of the last problems for me. I was hoping that the -n switch would disable caching and thus eliminate the writes to /var/cache/samba/winbindd_cache.tdb. But I haven't had much luck. To debug, I use the command string winbindd -i -d10 -n -s /etc/samba/smb.conf and I get the following output: [ 6796]: list trusted domains secrets_get_trusted_domains: got 0 domains Storing response for pid 6797, len 3240 fork_domain_child: domain PICTURE-FRAME no longer in 'startup' mode. Destroying timed event 82e24d8 "async_request_timeout" Retrieving response for pid 6797 Added timed event "async_request_timeout": 82e24d8 timed_events_timeout: 299/999938 child daemon request 19 process_request: request fn LIST_TRUSTDOM [ 6796]: list trusted domains secrets_get_trusted_domains: got 0 domains Storing response for pid 6797, len 3240 Destroying timed event 82e24d8 "async_request_timeout" Retrieving response for pid 6797 Added timed event "async_request_timeout": 82e24d8 timed_events_timeout: 299/999937 child daemon request 19 process_request: request fn LIST_TRUSTDOM This repeats indefinitely as far as I can tell. Each of these sections corresponds to a write action to the winbindd_cache.tdb file. Should I be able to stop writes to winbindd_cache.tdb? Am I missing something?
