Freddie,
=20
Thanks for your great help, now makes so much sense.
I still have a small problem, and I'm not sure if it is because hastd is =
running.
I can't initialize (hastctl create disk2) disk2
=20
This is what I did.
=20
1.. zpool offline tank /dev/dsk/hast/disk2
2. zpool status -x
[root@san /usr/home/jose]# zpool status -x
pool: tank
state: DEGRADED
status: One or more devices has been taken offline by the administrator.
Sufficient replicas exist for the pool to continue functioning =
in a
degraded state.
action: Online the device using 'zpool online' or replace the device =
with
'zpool replace'.
scan: scrub repaired 0 in 12h4m with 0 errors on Sun Sep 23 19:14:19 =
2012
config:

hast/disk9 ONLINE 0 0 0
hast/disk10 ONLINE 0 0 0
=20

=20
3. removed disk / insert a new one.
4. initialize
Hastctl role init disk2
[root@san /usr/home/jose]# hastctl status disk2
disk2:
role: init
provname: disk2
localpath: /dev/mfid2

[root@san /usr/home/jose]#=20
[root@san /usr/home/jose]# hastctl create disk2
[ERROR] [disk2] Unable to write metadata: Input/output error.
=20
=20
=20
I don't want to stop hastd since it will shut down the connection to my =
san.
=20
Do you have any suggestion?
=20
Thanks

=20
Since it's a HAST device, you have to initialise the disk via hastctl. =
Once that is done, the /dev/hast/disk2 GEOM device node will be created.
=20
Then you can 'zpool replace' it.
=20
One step at a time. :) And you've skipped a few.
=20
1. 'zpool offline' the defective disk
2. Physically remove the defective disk
3. Physically insert the new disk
4. Initialise it as a HAST resource via 'hastctl'
5. 'zpool replace' it using the /dev/hast node 6. Wait for the pool (and =
HAST) to resilver it 7. Carry on as per normal On Sep 23, 2012 2:28 PM, =
