Strange crash.
After restarting client, df -h crashes. If ls /mnt/glusterfs is run first, df -h runs fine. Verified on both clients.
Here is the bt from Ubuntu
Program terminated with signal 11, Segmentation fault.

Harris,
both the slowness bug and the segfault you reported have been fixed in the latest TLA patchset. Please update and confirm that the fixes work for you.
thanks,

Amar,
Anything on this bug. If you can tell me the tla command to get specific patch levels I will try to narrow to bug down further.

Hi Harris,
Thanks for cornering the bugs between 309-313 . We are looking into it.

I just tested a full zimbra backup on my mailbox with 308 client and 313 bricks and it completed in normal time with no errors. This is more evidence that the problem is client only and was introduced in 309-313 .

Some more testing:
Patch 308
time tar -cvf /mnt/glusterfs/test/test.tbz 0 1 2 3
real 6m47.947s
user 0m0.180s
sys 0m1.220s
Patch 313
time tar -cvf /mnt/glusterfs/test/test.tbz 0 1 2 3
real 9m21.909s
user 0m0.160s
sys 0m1.470s
Patch 313 also used 50% more memory.
This leads me to suspect the problem is in writebehind or posix-locks

Subject: Slowness and segfault with 313
Last weekend with 299 a full Zimbra backup completed in 27 minutes. This weekend with 313 the backup was only about 1/2 through after 5 hrs. I aborted the backup and the client crashed. The abort would have tried to remove about 4G of files from the /mnt/glusterfs/backups/tmp folder. The following BT was generated from the core:
