If you don't mind loosing everthing on the physical disk(s)... "DBAN" Darik's Boot and Nuke. http://sourceforge.net/projects/dban/ Unlike Gpart (and GParted) this will truly errase the disk. What you end up with a truly clean, and able to be used for whatever you want afterwards, with no odd problems. I found GParted in particular, though it destroys the partition tables OK, it does not remove the data on disk that was in the partition. As a result, I had terrible troubles a while ago, getting FBSD 9.2 to reload, after I seriously screwed something up. GParted didn't do the job, I kept getting strange lib errors during the reinstall (from CD.) DBAN did the job, but it does take time, as it writes random noise to the entire physical disk, sector by sector. The re-install after that, just worked, no errors. The price is right, but take care, once let loose, that's it, there is no turning back. > Hi, > > While experimenting ZFS, I've ended up with a zpool that can't be imported: > > 8:41pm# zpool import > pool: lake > id: 10528535549827216272 > state: UNAVAIL > status: One or more devices are missing from the system. > action: The pool cannot be imported.
