The vendor wanted to come in and replace an HDD in the 2nd X4500, as it
was "constantly busy", and since our x4500 has always died miserably in
the past when a HDD dies, they wanted to replace it before the HDD
actually died.
The usual was done, HDD replaced, resilvering started and ran for about
50 minutes. Then the system hung, same as always, all ZFS related
commands would just hang and do nothing. System is otherwise fine and
completely idle.
The vendor for some reason decided to fsck root-fs, not sure why as it
is mounted with "logging", and also decided it would be best to do so
from a CDRom boot.
Anyway, that was 12 hours ago and the x4500 is still down. I think they
have it at single-user prompt resilvering again. (I also noticed they'd
decided to break the mirror of the root disks for some very strange
reason). It still shows:
raidz1 DEGRADED 0 0 0
c0t1d0 ONLINE 0 0 0
replacing UNAVAIL 0 0 0 insufficient replicas
c1t1d0s0/o OFFLINE 0 0 0
c1t1d0 UNAVAIL 0 0 0 cannot open
So I am pretty sure it'll hang again sometime soon. What is interesting
though is that this is on x4500-02, and all our previous troubles mailed
to the list was regarding our first x4500. The hardware is all
different, but identical. Solaris 10 5/08.
Anyway, I think they want to boot CDrom to fsck root again for some
reason, but since customers have been without their mail for 12 hours,
they can go a little longer, I guess.
What I was really wondering, has there been any progress or patches
regarding the system always hanging whenever a HDD dies (or is replaced
it seems). It really is rather frustrating.
