Tonight I was manually running a scrub on my ZFS pool for the first
time. After a few minutes of operation, sound began repeating and the
computer spontaneously rebooted.
All I have in the logs is:
*Jun 20 22:31:46 nexus root: ZFS: checksum mismatch, zpool=mypool

I'm not sure if it was a coincidence or not, but it crashed while I was
doing a zpool iostat 1.
Any ideas about the ZFS error shown above ?
