I burned through about 3 disks before I figured it out. Nothing in the
logs made me think this but the eventual failure of the disks alerted me
that something hardwarish was happening.

Well, might be the reason. 8 drivers is certainly limit too much for a

How did you figure out the reason for errors on your system?

Careful... are you overtaxing your power supply? My 148 system was
behaving like that when I put too many drives in an ultra 20.

Hi,
I have SunOS 5.11 oi_148 installed on my storage server with 8 disks
in raidz2 pool.
It hangs about once in a week and I had to restart it.
Can you help me troubleshoot it?
It has some zfs volumes shared over nfs and afpd. (afpd is
unfortunately a development version to satisfy OSX Lion).
roks@data:~$ afpd -V
afpd 2.2.0 - Apple Filing Protocol (AFP) daemon of Netatalk
afpd has been compiled with support for these features:
AFP3.x support: Yes
TCP/IP Support: Yes
DDP(AppleTalk) Support: No
CNID backends: dbd last tdb
SLP support: No
Zeroconf support: Yes
TCP wrappers support: Yes
Quota support: Yes
Admin group support: Yes
Valid shell checks: Yes
cracklib support: No
Dropbox kludge: No
Force volume uid/gid: No
ACL support: Yes
EA support: ad | sys
LDAP support: Yes
It also has time-slider enabled, which is pretty buggy peace of hmmm
software, but it shouldn't cause server to crash or hang.
So the problems start with nfs and/or afpd timeouts on clients, but
I still can ssh to the server. Can't read any files or logs though.
Then network service disappears in a minute or few minutes, console
becomes frozen and I have to do hard restart at that point.
Where should I look to understand what causing this?
Since I can't reproduce the problem, I'd like to get prepared when
it happens next time.
I couldn't find anything unusual in the logs after restart.
time-slider complains for some reason about space on rpool

Aug 31 19:41:36 data time-sliderd: [ID 702911 daemon.warning] rpool

Where does it see 80%?
