My old desktop (with SCSI disks) died, and I'd been limping along on a loaner until the new one (with SATA disks) arrived, which happened yesterday. The steps needed to migrate the data from one to the other turned out to be remarkably simple, so I thought I would share them in case anyone else ever runs into this. The old box had a single pool:
NAME SIZE USED AVAIL CAP HEALTH ALTROOT space 68G 16.6G 51.4G 24% ONLINE - with two file-systems therein: NAME USED AVAIL REFER MOUNTPOINT space 16.6G 50.3G 99K /export/home space/jbeck 12.2G 50.3G 12.2G /export/home/jbeck space/local 4.25G 50.3G 4.25G /usr/local First, on the new box, I ran: % zpool create space mirror c2d0 c3d0 Then I temporarily tweaked /etc/ssh/sshd_config and /.ssh/authorized_keys to allow root from the old box to ssh to the new without being prompted for a password (not sure if this step was needed or not), then on the old box I ran: % zfs snapshot -r [EMAIL PROTECTED] % zfs send space/[EMAIL PROTECTED] | ssh newbox zfs recv -d space % zfs send space/[EMAIL PROTECTED] | ssh newbox zfs recv -d space The two send/recv runs took roughly 30 and 10 minutes respectively, much less than the almost two hours that the back-to-back tar method used to take to do this. Finally, on the new box, I ran: % zfs set mountpoint=/export/home space % zfs set mountpoint=/usr/local space/local % zfs set sharenfs=on space/jbeck space/local And that was it!
