Re: [Gluster-devel] Too many open files

I already looked there, and my file-nr allocated is much lower than file-max. It might be hitting some other limit, perhaps even a limit imposed by the bash that started glusterfsd. Still it really seems like there shouldn't be so many allocated file descriptors lying around (no files should currently be open, and rsync wouldn't have left large numbers open at the same time, I assume), so I think it's a bug where GlusterFS is not closing all the file descriptors it opens or allocates.

Thanks,

Brent

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
