Re: [zfs-discuss] zpool always thinks it's mounted on another system

Rich Tue, 19 Sep 2006 21:33:54 -0700

Hi all,
Has anyone else had any thoughts on this, or should I just sit patiently and hope the problem is resolved somehow because I'm missing something obvious or file something somewhere that I don't know about?

Thanks,
- Rich

I do the 'zpool import -f moonside', and all is well until I reboot, at which point I must zpool import -f again.

Below is the (lack of) 'zdb -C' output:

action: The pool can be imported using its name or numeric identifier.
        The pool may be active on on another system, but can be imported using
        the '-f' flag.
config:

Can you send the output of 'zdb -l /dev/dsk/c2t0d0s0' ?   So you do the
'zpool import -f' and all is well, but then when you reboot, it doesn't
show up, and you must import it again?  Can you send the output of 'zdb
-C' both before and after you do the import?

Thanks,
