I've followed the advice and installed FreeBSD-8.0BETA3-amd64 on that server. OS resides on dedicated SATA HD, so all other hard drives left untouched. Now I cannot see zfs pool online. I've enabled ZFS in /etc/rc.conf, reboot the server, but I cannot see my zpool. zen# zpool list no pools available zen# I remember ZFS relies on hostid, and I've checked my current hostid is identical to the one that I had when I ran 7.2. What do I do now to see my zpool again? Thanks, Mikhail.
