Haha, I’m having fun with ZFS but am stuck and cannot find any proper references that shows the way out.
I decided to unmirror a mirror so it can be wiped and put back with a fresh format.
zpool split tank1 tank2
Which does not appear the be the way to go, digging a deeper hole I imported tank2 to tank1 which caused the ZFS lib to be lost. With an unstable system I rebooted with ada0 removed.
zpool now shows tank2 (exported) online and I can’t get anywhere.
tank2 has the previous suspect ada0, which is now ada3 with ada3p2.
The Disk Manager shows it dimmed as exported and online.
Once off line I would destroy the old ada0 (now ada3) and use gpart to backup and restore from ada1 (the known working boot drive).
But I need a pointer to how to solve this if someone wants to help…
OK, I booted off the DVD and sorted it out in a terminal which was much easier.
I got further than I’ve ever gone with ZFS and had a lot of fun especially with not loosing data while accidentally striping and then remirroring. (Gotta pay attention when using the GUI tool, I thought the one drive was a mirror but I had split it which made it not be part of a mirror anymore.)
I really appreciate the Installer’s options which makes it easy to work offline with the drives. (It’s hard to modify drives/pools that are in use.)
Having mirrors certainly saved the day, ZFS on mirror is a great combination. (And of course that is no replacement for backup as many of us have seen more than one drive die at the same time.) Love to have the time to really play with the abilities of ZFS.
Having had some odd behavior on my O/S mirror since I originally installed a year ago I decided to reinstall and lo and behold I now got things such as autoloading of USB devices which never worked earlier. That alone made the whole extra time to reinstall all appl worth while.
Though with the nvidia driver (latest from DVD) I still cannot leave X and have legible terminals (just some thick vertical colored lines instead of text).
[I can see why nobody responded to what looked like a big mess.]
