I have an HP DL360 with a pair of 1TB seagate disks that's been running -STABLE with a ZFS root partition set up using the tools available here: http://yds.coolrat.org/zfsboot.shtml It's been working great. As part of trying to understand what's going on, I csup'ed to -RELENG earlier today and rebuilt/installed the kernel and world whilst running on the DL360, so everything should be current. I tried to move the disks into an HP DL320 G4 and it fails to boot because it can't find /dev/mirror/boot (which it wants to mount onto /strap and then parts get nullfs'ed onto /boot and /rescue). It gives me the opportunity to start a shell, and from that shell I can do a zfs mount -a and get all of the zfs filesystems mounted, but there's nothing in /dev/mirror. No gmirror status and list are silent. I can move the disks back into the older machine and they work fine. I've run fdisk -s ad4 and bsdlabel -A /dev/ad4s1a and diffed the output from the two machines and they're identical. I've booted with kern.geom.mirror.debug=2 and the DL320G4 tastes /dev/ad4s1a (along with everything else) but doesn't do anything with it. Any ideas? g.
