I don't have an answer to your question exactly because i'm a noob and i'm not using mac but i can say that on FreeBSD which i'm using atm there is a method to name devices ahead of time so if the drive letters change you avoid this exact problem. I'm sure opensolaris and mac have something similar.
As far as your issue goes i THINK you can just export/import the pool.....i'm sure someone in this list who knows more than me will speak up on offical stuff =) 2009/7/28 Avérous Julien-Pierre <no-re...@opensolaris.org> > Hi ! > > I'm a Mac User, but I think that I will get more response here about this > question than on a Mac forum. > And first, sorry for my approximative English. > > I have a ZFS Pool named "MyPool" with two device (two external USB drive), > configured as mirror : > > NAME STATE READ WRITE CKSUM > MyPool ONLINE 0 0 0 > mirror ONLINE 0 0 0 > /dev/disk2s2 ONLINE 0 0 0 > /dev/disk3s2 ONLINE 0 0 0 > > > The drive disk3 is unexpectedly unplugged for some reason (power failure, > etc), but the drive is perfectely functional. > > I have plugged an other driver before replugging the unplugged drive.
