Hi All,
Just a note that after catch up with -current my zfs pool kissed good =
bye. I'll omit details about its last days and go strait to the final =
state:
Creating pool from scratch:
#zpool create tank raidz da{1..3}
#zpool status
pool: tank
state: ONLINE
scan: none requested
config:
NAME STATE READ WRITE CKSUM
tank ONLINE 0 0 0
raidz1-0 ONLINE 0 0 0
da1 ONLINE 0 0 0
da2 ONLINE 0 0 0
da3 ONLINE 0 0 0
errors: No known data errors
#zfs list
NAME USED AVAIL REFER MOUNTPOINT
tank 140K 3,56T 40,0K /tank
Let's use some space out of it.
#dd if=3D/dev/zero of=3D/tank/foo
^C250939+0 records in
250938+0 records out
128480256 bytes transferred in 30.402453 secs (4225983 bytes/sec)
Oops...
#zpool status
pool: tank
state: ONLINE
status: One or more devices has experienced an unrecoverable error. An
attempt was made to correct the error. Applications are =
unaffected.
action: Determine if the device needs to be replaced, and clear the =
errors
using 'zpool clear' or replace the device with 'zpool replace'.
see: http://illumos.org/msg/ZFS-8000-9P
scan: scrub repaired 5K in 0h0m with 0 errors on Sat Jan 19 23:11:20 =
2013
config:
NAME STATE READ WRITE CKSUM
tank ONLINE 0 0 0
raidz1-0 ONLINE 0 0 0
da1 ONLINE 0 0 1
da2 ONLINE 0 0 0
da3 ONLINE 0 0 1
At some state (more data copied) it is enough to do another scrub run to =
trigger new cksum errors / unrecoverable file loss.
I do not see any error messages from kernel and smartctl output has zero =
error counters.
Full memtest cycle seems to be all right.
Kernel built with gcc is suffering from same sympthoms.
Tried to create raidz pool out of files and it worked fine (even placed =
one chunk to UFS made out of da0).=20
Any idea what it can be?
Last kernel which did work was back from October 2012.
Thanks,
Alexander.=
