Hello,
one drive of my mirror failed today, but 'zpool staus' shows it "online".=
Every process using a ZFS mount hangs. Also 'zpool offline /dev/ad1'=20
hangs infinitely.
Here's the dmesg of the failing (and correctly detached) device:
ad1: TIMEOUT - FLUSHCACHE48 retrying (1 retry left)
ata3: port is not ready (timeout 10000ms) tfd =3D 00000080
ata3: hardware reset timeout
ad1: FAILURE - device detached
But:
zpool status
pool: URUBAmirrorP1
state: ONLINE
status: One or more devices are faulted in response to IO failures.
action: Make sure the affected devices are connected, then run 'zpool=20
clear'.
see: http://www.sun.com/msg/ZFS-8000-JQ
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
URUBAmirrorP1 ONLINE 0 7K 0
ad1 ONLINE 3 14,9K 0
ad2 ONLINE 0 0 0
Reboot doesn't work, somebody had to reset the machine.
How should such a error event be handled??? Isn't a mirror useless if=20
there's no way to continue with one remaining good drive?
If the OS was on the same pool the complete machine is unaccessable with =
a failing drive..?!?
Thanks,
-Harry
