I have an existing ZFS RAID-Z pool I created in 7.0-RELEASE. I am having problems with a certain port after doing a portsnap update. I want to try a fresh install of 8.1-RELEASE. I do not want to try and go through a build world.
I will have my existing pool data backed up to be safe, but would like to avoid having to copy it all back. How can I mount an existing, older version ZFS RAID-Z array on a fresh install? I do not really need to have the newer version file system for the updated features of ZFS at this time. The stability fixes will be enough for me. This is only a data storage array, it is not what the system boots from.
Sorry for being a noob, I have read about ZFS upgrades being fine after building world, but I did not see anything specific on a fresh install.
Reading the Manpages for zpool, it seems like I need to export the ZFS pool first on the old system, then import it once the new system is installed. Is that all there is to it? I do not need to backup any exported pool configuration data, or specify the drives that make up the pool again?
Thanks for looking, hope it's as easy as it sounds.
