Well I have a 10TB (5x2TB) in RAIDZ on VirtualBox got it all working on Windows XP and Windows 7. SMB shares back to my PC, great managed the impossible! Copied all my data over form a loads of old external disks, sorted it, all in all 15 days work (my holiday :-)) Used raw disks to the VirtualBox so was quite ok performance.
Then Opensolaris (2009.6) crashes as I tried to close it down, in the end had to power of the VirtualBox. rebooted, I then get this: #zpool status pool: array1 state: FAULTED status: The pool metadata is corrupted and the pool cannot be opened. action: Destroy and re-create the pool from a backup source. see: http://www.sun.com/msg/ZFS-8000-72 scrub: none requested config: NAME STATE READ WRITE CKSUM array1 FAULTED 0 0 1 corrupted data raidz1 ONLINE 0 0 6 c9t0d0s0 ONLINE 0 0 0 c9t1d0s0 ONLINE 0 0 0 c9t2d0s0 ONLINE 0 0 0 c9t3d0s0 ONLINE 0 0 0 c9t4d0s0 ONLINE 0 0 0 pool: rpool state: ONLINE status: The pool is formatted using an older on-disk format.

01:58:18 BST =============================================== Infact July 13 is ok thats when I was last adding files and moving things about so thats not a bad point to return to.... So how do I manage to "roll-back" to txg = 335425 so I can hopefully get my 10TB back? Or is the answer return to doing HW raid under NTFS and windows directly? I heard people at sun may be working on a tool that can roll-back to a txg is it about (yes I understand the issue of you can't roll back as a freeded block may have been re-used) but I'd happ;y loosse one of my 6GB files to get the other 6TB back thanks!! PLEASE PLEASE any help really appreciated.
