<div dir="ltr">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:

<div>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!).<br>
<div><br>
</div>
<div>Also, I've had many improper shutdowns of the hosts and
VMs, and this was the first time I've seen a ZFS
corruption. </div>

</div>
<div>I know I'm repeating myself, but my question is still:</div>
<div>- 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? <br>

I rember that post, but as I do not use Veem, I didn't had anything
to contribute. From my understanding though, your issue could only
be caused by a write-error, since why should you get a PSOD
otherwise? The issues I had were caused by "read-erorrs", at least
that was reported by the Linux kernel. In both cases the LUN-depth
could be an issue and I will check with my initiator, if I should
lower the queue depth.<br>
<br>
As far as your question goes, I'd say: as long as a scrub doesn't
reveal any issue and the zpool's state is clean, I'd use it.<br>

Hi,<br>
<br>
the PSOD you got can cause the problems on your
exchange database.<br>
<br>
Can you check the ESXi logs for the root cause
of the PSOD?<br>
<br>
I never got a PSOD on such a "corruption". I
still think this is<br>
a "cosmetic" bug, but this should be verified by
one of the ZFS<br>
developers ...<br>
