I'm a new user of ZFS and I have an external USB drive which contains
a ZFS pool with file system. It seems that it does not get auto mounted
when I plug in the drive. I'm running osol-0811.
How can I manually mount this drive? It has a pool named rpool on it.
Is there any diagnostics commands that can be used to investigate the
contents of the pool or repair a damaged file system ?
rmformat shows that the physical name of the USB device is:
/dev/rdsk/c4t0d0p0
If I try '# zpool import" I get:
pool: rpool

state: UNAVAIL
status: The pool was last accessed by another system.
action: The pool cannot be imported due to damaged devices or data.

Did you try this:
zpool import -f rpool someothername
I think there are two reasons it won't import:
1) It was last accessed by another system (or maybe the same
one but it had a different hostid at the time) so you need
to use the -f flag.
2) There is probably another pool called rpool (the one you
are running from), right ?
I think this pool is just too modern for the system you are trying to
import it on as it is UNAVAIL due to newer version.
Here's an example:
r...@jax # mkfile -n 64m version
r...@jax # zpool create version /var/tmp/version
r...@jax # zpool upgrade version
This system is currently running ZFS pool version 10.
Pool 'version' is already formatted using the current version.
r...@jax #
r...@jax # rcp version theorem:/var/tmp
On the other host:
r...@theorem # zpool upgrade
This system is currently running ZFS version 4.
All pools are formatted using this version.
r...@theorem # zpool import -d /var/tmp
pool: version
id: 2589325003567752919
state: FAULTED
status: The pool is formatted using an incompatible version.
action: The pool cannot be imported. Access the pool on a system
running newer
software, or recreate the pool from backup.
see: http://www.sun.com/msg/ZFS-8000-A5
config:
version UNAVAIL newer version
/var/tmp/version ONLINE
r...@theorem #
There's a difference in messages though, but older host in my case is
running Solaris 10 U4, so it may explain it. Anyway, I think pool
version is the real reason here.
