Over the weekend, I installed opensolaris 2008.11 onto a removable harddisk on my laptop (having previously removed the zfs bootable snv_103 imaged harddrive). - side note: opensolaris could do with a companion cd as it takes a long long time to install the usefull/essential software from the repository :-( . Having installed opensolaris 2008.11 I thought I might try to mount the zfs bootable snv_103 drive and copy all the data over (i.e. in a similar way to when I moved from ufs to zfs boot, a while back). I struggled to be able to mount the old disk and as I had to do some ''proper work'' removed the opensolaris 2008.11 harddisk and put back the snv_103 harddisk. All worked fine, as before. When I later found some time, I tried to mount the opensolaris 2008.11 harddrive (now in a usb caddy) from the booted snv_103 drive, by entering: zpool import -f rpool It complained about stuff being already mounted but sure enough I could still see the original pool ''rootpool'' of snv_103 and the pool ''rpool'' of opensolaris 2008.11 image got some sort of mention as well, when I did ''zfs list'' and I could still see my familiar snv_103 home directory. A reboot soon changed all of that :-( On booting it comes up with: . . . Reading ZFS config: done Mounting ZFS filesystems: (1/6)cannot mount ''/'' : directory is not enpty (6/6) svc:/system/filesystem/local/:default: WARNING: /usr/sbin/zfs mount -a failed exit status 1 I get a login prompt and can login ok.

''zfs list'' gives: USED AVAIL REFER MOUNTPOINT rootpool 78.6G 191G 37k / rootpool/ROOT 18.7G 191G 18k /ROOT rootpool/ROOT/zfs_103 3.81G 191G 11.3G /.alt.tmp.b-iR.mnt/ rootpool/ROOT/zfs_104 14.9G 191G 9.34G / rootpool/dump 3.25G 191G 3.25G - rootpool/home 50.3G 191G 41.9G /export/home rootpool/swap 3.43G 191G 105M - rootpool/u01 2.84G 191G 2.78G /u01 Also swapping the opensolaris 2008.11 harddisk into the laptop drive bay no longer boots up opensolaris 2008.11 either. How do I get back to a bootable system e.g. what zfs or zpool commands will get me out of this hole - before I dig myself in deeper. Thanks for your time. -- This message posted from opensolaris.org
