XFS corruptions

[Sandeep Patel]

Yes, they only thing we changed from default is the isize.

We are running the latest version on the firmware. We previously upgraded the firmware on these thinking it would solve the problem.

The problems seem to occur at random. The load to these units are quite minimal at the moment and we are still having issues. 

Thanks
Sandeep

Looks plain defaults... you didn't apply any customization, did you?

Hum, strange, are you running the latest RAID firmware on the controllers?

Does this happen more often when the array is rebuilding, or verifying, or when the system is under heavy IO? Or does it happen just completely at random?

If you're not afraid of running binaries from unknown source, here's a
4.2.0 version I've built recently:
