Hi, I'm rather new to FreeBSD and I'm having trouble with ZFS and gmirror. I've used this guide to install FreeBSD 7 on ZFS: http://www.ish.com.au/solutions/articles/freebsdzfs This goes flawless, however, the /bootdir is still just /dev/ad01sa (in my case), so if that disk breaks, I still can't boot from ad1. So I thought I could just make a gmirror containing /dev/ad0s1a and ad1s1a and use that for /bootdir. This however does not work. What I did is: - gmirror load - gmirror label -v -b round-robin gm0 /dev/ad1s1a - newfs /dev/mirror/gm0 - mount /dev/mirror/gm0 /mnt/tmp - dump -L -0 -f- /bootdir | (cd /mnt/tmp && restore -r -v -f-) - edit /etc/fstab and /mnt/root/etc/fstab: change all references to ad0s1a by /dev/mirror/gm0 - echo 'geom_mirror_load="YES"' >> /boot/loader.conf - echo 'geom_mirror_load="YES"' >> /mnt/tmp/boot/loader.conf - reboot However: I can see the bootprocess starting first ZFS followed by a message saying it's waiting for GEOM gmirror to start, which it does after a little while and then I get a prompt where I can manually tell the system where the root filesystem is. And if I tell it zfs:system/ root it does not work (my zpool is named system). Anyone know what I'm doing wrong and what's the best way to do this? Thanks in advance!
