I am going to attempt to get the kernel output by running my tests in a vm (so I can get a dump of the console) and seeing if I get the same results.

What kernel version are you using on your client?

Hello,

I've been working to deploy ceph recently and have been conducting some performance tests and have ran into some problems. I've created an rbd image, mapped it on a client and put a file system on it. I've tried with both ext4 and xfs to which the same results occur. After a while the system running bonnie will lock up leaving some kernel messages on the console and requires a hard reset. This has occurred on two different machines, one was
a monitor and the other was a plain client.


My setup: 5 osds and 3 monitors (2 monitors are on osd machines). Replica is set to 3 on the pool that my image is stored and the cluster was healthy at
the start. I am using the 0.56 packages for ubuntu.

Any ideas on what is causing the system to lockup/panic?

Thanks,

-Trevor Adams
