Hi Dick,
Yes, you can use zfs send|recv to recreate the root pool snapshots on
the other disk in addition to the other steps that are needed for full
root pool recovery is my assessment. See the link below, following the
steps for storing the root pool snapshots as snapshots rather than
files. I should attempt a similar migration to see how it goes since
I've only tested this recovery going from a local-->remote system and
back, but not having two potential root pools on the same system. (?)
Maybe someone else can advise better but to me your choices are to
recreate the root pool on the second disk or reinstall. Or, if
possible, connect another larger disk and attach it to the original root
disk or even replace the smaller root pool disk with the larger disk.
Thanks,
Cindy

Yes, I know, but in this case the second disk indeed is smaller ;-(
So I wonder, should I reinstall the whole thing on this smaller disk and
thren let the bigger second attach? That would mean opening up the case
and all that, because I don't have a DVD player built in.
So I thought I'd go the zfs send|recv way. What are yout thoughts about this?
Another thought is that a recent improvement was that you can attach a
disk that is an equivalent size, but not exactly the same geometry.
Which OpenSolaris release is this?
b131
And this only works if the difference is realy (REALLY) small. :)
