Brent,
thank you so much for your efforts of sending the output!
from the log it is clear the leak fd's are all for directories. Indeed
there was an issue with releasedir() call reaching all the nodes. The
fix should be committed today to tla.
Thanks!!

I avoided restarting, as this issue would take a while to reproduce.
jupiter01 and jupiter02 are mirrors of each other. All performance
translators are in use, except for writebehind (due to the mtime bug).
jupiter01:
ls -l /proc/26466/fd |wc

See attached for ls -l output.
jupiter02:
ls -l /proc/3651/fd |wc

Note that it looks like all those extra directories listed on jupiter01
were locally rsynched from jupiter01's Lustre filesystems onto the
glusterfs client on jupiter01. A very large rsync from a different
machine to jupiter02 didn't go nuts.
Thanks,

Brent,
I hope the system is still in the same state to dig some info out.
To verify that it is a file descriptor leak, can you please run this
test. On the server, run ps ax and get the PID of glusterfsd. then do
an ls -l on /proc/<pid>/fd/ and please mail the output of that. That
should give a precise idea of what is happening.
If the system has been reset out of the state, please give us the
spec file you are using and the commands you ran (of some major jobs
like heavy rsync) so that we will try to reproduce the error in our
setup.

I put a 2-node GlusterFS mirror into use internally yesterday, as
GlusterFS was looking pretty solid, and I rsynced a whole bunch of stuff
to it. Today, however, an ls on any of the three clients gives me:
ls: /backup: Too many open files
It looks like glusterfsd hit a limit. Is this a bug (glusterfs/glusterfsd
forgetting to close files; essentially, a file descriptor leak), or do I
just need to increase the limit somewhere?
Thanks,
Brent
