[Linux-cluster] GFS 6 hang during file copy..



Title: GFS 6 hang during file copy..

I've got a 3 node cluster consisting of DL380's running RHAS3 update 3 with RHGFS 6.0.0-15.
The locking is being done on the cluster nodes themselves and are not external. I set up nfs to
export one of the gfs mount points and this was working fine.

I then tried to populate the gfs mount point with about 24GB if files from another system using scp
to do some testing. During that copy, gfs froze. That is to say I can still interact
with the nodes unless I do anything that might query the gfs mount (is ls -l /gfs1)  this hangs the
machine.

After a reboot things were fine. I did a gfs_tool df /gfs1 and there were ~79000 inodes being used,
and right around 20 GB (just under actually) used. The filesystem itself is 300+GB.

My question, if it's the right one, is did I hit a limit in inodes? As I recall, GFS maps inodes from the
host somehow. Is there a way to increas the numbe so that I can actually use the space I have or
must I reduce the size of the filesystem?

Of course I could be completely off base and if so, please let me know…

Thanks


Corey
