This comment has only to do with booting an old drive on a different computer--a bit of a tangent to this discussion: I've also used this to migrate to a new computer with larger disks. The only caveat I've run into is you need to move from SATA/AHCI to the same, or SATA/IDE to the same. They c

Richard already addressed this process, but I do this basic concept all the time (moving to a larger disk or new computer). I simply create the partition on the new disk with format, then "zpool attach -f" the larger drive. Once done mirroring, use installgrub as normal. Remove the smaller dr

I did notice the findroot command, but I don't know what I'm doing when it comes to Grub. The video is up http://www.youtube.com/watch?v=tpzsSptzmyA - just me droning on for ten minutes and it is aimed at people following me, so I do a lot of explaining the basics. I have to agree with a previ

Another question ... I did this as a test because I am aware that zpools don't like drives switching controlers without being exported first. The question was, what would a rpool boot drive do if it was put on a different controller and then booted? I shut down, took away c7 and hooked c19 up t

Hi Cindy, Won't I have a problem putting the grub in slice 0 when it is also allocated to the zpool? Or do the two co-exist? I've been trying to shift the boot partition from slice 8 to slice 0, and then make slice 1 the hog, but I just can't get to grips with the partition command in order to

Hi Michelle, Your previous mail about the disk label reverting to EFI makes me wonder whether you used the format -e option to relabel the disk, but your disk label below looks fine. This also might be a known bug (6419310), whose workaround is to use the -f option to zpool attach. An interim
