(dovecot v1.2.16)
I've notice the log notices about increasing /proc/sys/fs/inotify/max_user_instances on my servers, and started wondering if inotify works for network/cluster filesystems..
I found this:
http://www.ibm.com/developerworks/forums/thread.jspa?threadID=311194which says that there's no mechanism for one node to tell another node that a directory changed for GPFS.. And I would assume the same applies for NFS and other network filesystems. (Yes I know, we should use director to make users sticky to one host -- but we're not yet ready for that for lmtp).
So, are there any recommendations for what settings one should use for for filesystems where inotify woun't work ? Are there settings for disabling it (without recompiling)?
And does mailbox_idle_check_interval happen in addition to inotify, so that clients will be notified even with a broken inotify ?
