When I tried to bring it back online the softraid volume would not
come back.
What did you do? Rebooted?
The host was down at ddb, after collecting the above information I
reset the host.
And no mention of reasons anywhere? What doas 'bioctl -i softraid0'
say?
no mention of anything anywhere. bioctl returns with nothing
# bioctl -i softraid0
#
# bioctl -i -v softraid0
#
And sd9 got assigned, I suppose.
Correct.
For rebuilding parity when a drive failed, yes. But it does not look
like one of your chunks (drives) failed, does it?
As far as I can tell no drive failed, the box just panicked.
Is your sd1 still the same physical drive? Do you have indications it
is
the chunk that failed? Why are you rebuilding parity with that chunk?
My tests back then succeeded in rebuilding parity of a volume with a
new
chunk like that.
Drives have not changed, I was uncertain what chunk referred to, so
perhaps
this was just the wrong command, from reading the man page and
discussing
with a few others on irc this seemed like something valid to try.
And these show the expected output?
I think so ...
