Re: glusterfs crash with mainline-2.5 patch 260 with dbench

Harris,

I only ran 'dbench -t 10 10' without the -c. When not using the -c it uses all the test cases. Checking out 261 on this box and trying again. Ran 261 on another box with 3 parallel rsync's but the mount froze a few times and made rsync fail but mount became responsive after the timeout.

Dale,

I have never used dbench before but I did the following:

/mnt/glusterfs $ sudo dbench -t 10 10 -c /usr/share/dbench/client_oplocks.txt 10 clients started
   0     62477  6.35 MB/secc
Throughput 6.35386 MB/sec 10 procs

This was with patch 261. How does this compare to want you did? I was trying to reproduce your crash.
