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? Thanks, g.
