ZFS and disappearing glabels
I've set up a system as described here. http://wiki.freebsd.org/RootOnZFS/ZFSBootPartition Using the 8.0 Release DVD and then csup'ing to RELENG_8 and rebuilding. I set it up with a single drive, the only change that I made was that after creating ad10s1a I glabeled it as disk0, then added /dev/label/disk0 to the pool. That worked great. Then I added a second larger drive, giving it an MBR, a bsd label, and an s1a partition that I glabeled as disk1. I attached that to the pool and it resilvered happily. However, when I rebooted I found that the pool now consists of label/disk0 and ad12s1a. I detached ad12s1a, relabeled it as disk1, and attached disk1 to the pool again. It resilvered fine. Running strings on /boot/zfs/zpool.cache shows /dev/label/disk0 and /dev/label/disk1. But, when I reboot I find I'm back to label/disk0 and ad12s1a. At this point strings on zpool.cache lists /dev/label/disk0 and ad12s1a. I'd like to have the device independence of using labels, and am also worried about problems caused by the different disk sizes (since the glabeled partition is 512 bytes smaller). Any ideas what's going wrong?

Any ideas what's going wrong? Thanks, i ran into the same issues. every reboot i would have to fight to relabel the drive (on 7.2). I upgraded to 8 and used GPT for everything (and ZFS on root) and i have not had any issues. I would recommend going that route. You can still label the drives with labels. This is the docs I followed: http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot/Mirror Works great!

Maybe you accidentally used the manual method on the second disk? Or it could be that the GEOM metadata is overwritten. This metadata is written in the last sector, explaining the size difference you noticed. If the metadat is overwritten, GEOM will not recognize it.

This is the docs I followed: http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot/Mirror Works great! I'm running something like that on another machine, but can't on this one. The gory details include the fact that this is a mac pro. It's EFI firmware only does magic bios emulation if it sees an MBR formatted disk and so setting things up via GPT won't work for me. I did try it using the link that you pointed to above and it wouldn't boot. Tried it via the apple's firmware choose a boot disk by holding down the option key trick and via rEFIt. g. ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org

Maybe you accidentally used the manual method on the second disk? [...] +1 bonus point to Roland, just in time under the New Years wire. I created the first label with 'glabel label', which creates an automatic label, but created the second with 'glabel create' (assuming it was a synonym), which creates a manual label. I did a detach, relabeled, reattached, and away I go.
