First time user of Solaris and ZFS .... I have Solaris 10 installed on the primary IDE drive of my motherboard. I also have a 4 disc RAIDZ setup on my sata connections. I setup up a successful 1.5TB ZFS server with all discs operational. Well ... I was trying out something new and I borked my Solaris install HDD; the main problem is that I also had my RAIDZ zpool operational. I don''t think I can salvage my Solaris install (just not experienced enough), though if I reformat and install Solaris back on the IDE HDD, will I be able to save all the data on my RAIDZ after install? I didnt take any snapshots of my existing ZFS. Will I be able to save my data on the RAIDZ and remount the ZFS after reinstall, or am I screwed? Please help ...

"Zpool import" is your friend.. Yes you still have your pool!

''zpool import'' will locate the pool on a fresh install. If possible, you should perform a ''zpool export'' on the current system before reinstalling Solaris, because ZFS will refuse to import a pool that wasn''t exported if it is marked as being in use by a different system (in this case the previous install). If exporting is not possible, ''zpool import -f'' will ignore that warning and allow importing anyway. -Albert
