Hi all,
I have a backup server running
FreeBSD d0028.nessops.net 9.0-RELEASE FreeBSD 9.0-RELEASE #0: Tue Jan 3 =
07:46:30 UTC 2012 =
root@farrell.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC amd64
There is a single ZFS pool used for storage, configured as such:
pool: tank
id: 13753647290422885969
state: ONLINE
action: The pool can be imported using its name or numeric identifier.
config:
tank ONLINE
raidz2-0 ONLINE
aacd1p1 ONLINE
aacd2p1 ONLINE
aacd3p1 ONLINE
aacd4p1 ONLINE
aacd5p1 ONLINE
aacd6p1 ONLINE
aacd7p1 ONLINE
aacd8p1 ONLINE
raidz2-1 ONLINE
aacd9p1 ONLINE
aacd10p1 ONLINE
aacd11p1 ONLINE
aacd12p1 ONLINE
aacd13p1 ONLINE
aacd14p1 ONLINE
aacd15p1 ONLINE
aacd16p1 ONLINE
The setup was running just fine for about a month and a half until =
yesterday when the machine hung hard. No problem, reset, comes back =
fine. Few hours later, it crashes again. Now any attempt to import the =
pool spins the disks for about 15-20 minutes and then wedges the =
machine. Before it hangs, "top" reports that the zpool command is =
dancing between active (CPU0), tx->tx, and bio states. Then the machine =
becomes unresponsive (both over the network and at the console) and must =
be reset.
I'm seeing some old diagnostics instructions from =
http://www.mail-archive.com/zfs-discuss@opensolaris.org/msg18818.html =
including running zdb -e -d and zdb -e -b, and they are running right =
now.
But I'm hopeful someone has more concrete advice, as this is a pretty =
important system to me.
Thanks!
Steven
