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:
which 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
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 ?
