I've a FreeBSD 7-CURRENT (as of 2007-10-09) running in a VirtualBox virtual machine and with all filesystems except /boot on ZFS. Now that we switched to 7.0-PRERELEASE and 8-CURRENT I today created another virtual machine and just cloned the disks (with "vboxmanage clonevdi", but it doesn't matter here). When I then booted the new virtual machine with the cloned disks, the root filesystem couldn't be mounted during boot via "zfs:zp1/root" as the ZFS pool "zp1" is no longer available. So I booted into the Fixit environment from "7.0-CURRENT-200709-i386-disc1.iso" and tried "zpool import". It was able to detect the pool on device ad0s1f. The problem just is that the hostid has changed (which is correct), so I thought I just have to re-import the ZFS pool with "zfs import -R /zp1 -f zp1". This still worked just fine: all filesystem were available under temporary /zp1 now (I had to use this alternative root or the Fixit environment is immediately dead). But once I then reboot into the system, the ZFS pool is again not found via "zfs:zp1/root"! In tried multiple times with various ways in the Fixit environment: "zfs import zp1" is denied because the hostid is different, "zfs import -f zp1" does the trick (although breaks the Fixit environent) but after reboot the ZFS pool again gone, "zfs import -R /zp1 -f zp1" does also the trick but here again the ZFS pool is gone after reboot. So, the silly question is: what is the correct way to reanimate a ZFS pool after the host has changed, so that one can again directly boot from from one of its filesystems (here "zp1/root")? -- rse_at_FreeBSD.org Ralf S.
