[OmniOS-discuss] ZFS data corruption

[wuffers]

Oh, the PSOD is not caused by the corruption in ZFS - I suspect it was the
other way around (VMware host PSOD -> ZFS corruption). I've experienced the
PSOD before, it may be related to IO issues which I outlined in another
post here:
http://lists.omniti.com/pipermail/omnios-discuss/2015-June/005222.html

Nobody chimed in, but it's an ongoing issue. I need to dedicate more time
to troubleshoot but other projects are taking my attention right now
(coupled with a personal house move time is at a premium!).

Also, I've had many improper shutdowns of the hosts and VMs, and this was
the first time I've seen a ZFS corruption.

I know I'm repeating myself, but my question is still:
- Can I safely use this block device again now that it reports no errors?
Again, I've moved all data off of it.. and there are no other signs of
hardware issues. Recreate it?
