Folks, I'm deploying new OpenAFS 1.6.0 DAFS file servers on fully update RHEL 6.1 servers and I've stumbled across a data corruption problem. My ext4 filesystem on the vice mounts are not getting corrupted, just the AFS volume data.
Our /vicep[ab] mounts are provided by an EMC Clariion SAN array using the PowerPath driver. Each of the two vice mounts have 4 paths and are not partitioned. I've directly formatted the /dev/emcpower[ab] block device as ext4. Of course, the /dev/emcpowerX device is mounted on /vicepX. Every hour our OCS Inventory agent runs which eventually runs "fdisk -l" to get statistics for the storage on the server. When I was moving test volumes to the new server and the agent ran fdisk -l the kernel would print: Nov 28 13:01:39 xxx kernel: sdc: unknown partition table Nov 28 13:01:39 xxx kernel: sde: unknown partition table Nov 28 13:01:49 xxx kernel: sdc: unknown partition table Nov 28 13:01:49 xxx kernel: sde: unknown partition table and the volume being moved at that exact time would be corrupt. Usually the server would soon detect this and salvage the volume, but the level of corruptions has varied. The above messages and corruption only seem to happen when volume moves are in progress. Running fdisk -l on an idle server produces no messages. Other things cause the above messages to be re-printed, such as running fsck -yf /dev/emcpowera. They occur during the early hours of the morning as well from something that appears to be related to a cron job I've not tracked down yet. I need some help in figuring out what is causing the corruption and, more importantly, how to fix things.
