When I used raw disk or GPT partitions, if disk order was changed the
pool would come up in 'DEGRADED' or UNAVAILABLE state. Even then all
that had to be done is export/import the pool. After the pool has
been re-imported it was back to ONLINE.
Hmm OK, I thought it supposedly DTRT for raw disks but apparently not.
Now I'm using GPT labels (gpart -l) specifically because that avoids
issues with disk order or driver change. The pool I've built from GPT
labels has survived several migrations between different
controllers/drivers adX (ata) -> daX (SATA disks on mpt) -> adaX
(ahci) and multiple drive permutations without any manual
intervention at all. All that was done on 8-RC1/amd64.
I have also successfully imported the pool on OpenSolaris and back
again on FreeBSD.
Damn, if I'd realised I'd have done that :)
Do you know if it's possible to change?
Check the archives for stable@ and f...@. I believe that there was a
thread not that long ago detailing exactly how to do that. IIRC,
while it took a bit of work, it wasn't difficult.
