Hi Greg,

You are running into this bug:

Currently, building a pool from files is not fully supported.

Thanks,

Cindy

Hello all,
I am using Opensolaris 2009.06 snv_129
I have a quick question. I have created a zpool on a sparse file, for instance:

zpool create stage c10d0s0
mount it to /media/stage
mkfile -n 500GB /media/stage/disks/disk.img
zpool create zfsStage /media/stage/disks/disk.img
I want to be able to take this file and back it up to tape. However, that is fine but if I reboot I see:

pool: zfsStage
 state: UNAVAIL
status: One or more devices could not be opened.  There are insufficient
        replicas for the pool to continue functioning.
action: Attach the missing device and online it using 'zpool online'.
   see: http://www.sun.com/msg/ZFS-8000-3C
 scrub: none requested
config:

        NAME                               STATE     READ WRITE CKSUM
zfsStage UNAVAIL 0 0 0 insufficient replicas /media/zfsStage/disks/disk1.img UNAVAIL 0 0 0 cannot open

I then tried:
$zpool online zfsStage /media/zfsStage/disks
     cannot open 'zfsStage': pool is unavailable
$ zpool online zfsStage /media/zfsStage/disks/disk1.img
     cannot open 'zfsStage': pool is unavailable

Am I doing something wrong? When I restore from tape how would I mount this if this sort of thing is coming up? Hopefully someone can help me out.

Thanks,
Greg
