[Gluster-users] Gluster 3.1 and NFS problem

[Shehjar Tikoo]

Hi

What kind of app/tool was running on the nfs mount point when it hung?

Here are some things we can do to debug further.
Please restart the NFS server daemon using the TRACE log level, remount 
NFS and restart the tests. That way I'll be able to zero-in on the 
operation that results in this bug.

To start the nfs server in TRACE log:

$ ps ax|grep gluster|grep nfs

Kill the process that is listed here.

Then use the same command line as in the ps output, except, change the 
-L and -l arguments so it looks like:

glusterfs -f <volfile> -L TRACE -l /tmp/nfs.log

Next:

$ dmesg -c >/dev/null;
to clear dmesg.

Remount and run your apps, and watch for "not responding" message in 
dmesg. When that happens, please email me /tmp/nfs.log.

Thanks
