I bought a 1 TB external USB disk from Western Digital (1) and put it in my
2008.11 machine.The machine discovered the disk directly and I did a 'zpool
create xpool c11t0d0´ command
# zpool list
NAME SIZE USED AVAIL CAP HEALTH ALTROOT
[...]
xpool 928G 81K 928G 0% ONLINE -
# zpool status
[...]
pool: xpool
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
xpool ONLINE 0 0 0
c11t0d0 ONLINE 0 0 0
errors: No known data errors
So fa, so good. Then I tried to create a ZFS filesystem and copy some data like
this
# zfs create -o casesensitivity=mixed xpool/data
# rsync -a /data/ /xpool/data
After that all commands involving disk access just hanged. zfs, zpool, df can´t
even end them with ctrl-c
Then I pulled the disk USB cable and inserted it again. Then the commands
worked again but I got errors like this. (Just for this disk)
# zpool status -v xpool
pool: xpool
state: UNAVAIL
status: One or more devices are faulted in response to IO failures.
action: Make sure the affected devices are connected, then run 'zpool clear'.

scrub: resilver completed after 0h0m with 0 errors on Sat Aug 15 00:23:35 2009
config:
NAME STATE READ WRITE CKSUM
xpool UNAVAIL 0 18 0 insufficient replicas
c11t0d0 UNAVAIL 12 27 0 experienced I/O failures
errors: Permanent errors have been detected in the following files:
<metadata>:<0x0>
<metadata>:<0x11>
<metadata>:<0x15>
<metadata>:<0x16>
<metadata>:<0x2a>
Trying to scrub makes all commands hang again...
# zpool scrub xpool (no output for 3 hours...)
So, is my disk dead or can I just try to create a new pool on it? Ideas???
