Hi all! On my server both parity drives have simultaneously failed. Though it's possible it's hardware and both drives happened to fail at the same time, that seems unlikely to me, especially since they're the newest drives in the server... but it's always possible the server was physically jostled or something.
I've tried removing them both from the array and re-adding them both individually and together, and swapping parity 1 and 2, but it always fails in the parity rebuild. It then does a read check, which passes.
Both drives pass SMART tests, though honestly I don't know how meaningful that is.
The rebuild seems to fail at a different point as well, sometimes getting several million writes on the parity drives, sometimes only a few thousand.
Any clues as to how to diagnose this, or confirm the drives have actually failed would be appreciated.
Thanks
