Folkses, I'm in an absolute state of panic because I lost about 160GB of data which were on an external USB disk. Here is what happened: 1. I added a 500GB USB disk to my Ultra25/Solaris 10 2. I created a zpool and a zfs for the whole disk 3. I copied lots of data on to the disk 4. I 'zfs umount'ed the disk, unplugged the USB cable 5. I attached the disk to a PC/Solaris 10 and tried to get the data 6. but I couldn't find it (didn't know about 'zfs import' then) 7. re-attached the disk to the Ultra25/Solaris 10 and now 'zpool status' tells me that the pool is FAULTED and the data is corrupted. SUN support tells me that I have lost all data. They also suggested to try this disk on a Nevada system which I did. There the zpool showed up correctly but the zfs file system didn't.
If I do a hex dump of the physical device I can see all the data but I can't get to it... aaarrrggghhh Has anybody successfully patched/tweaked/whatever a zpool or zfs to recover from this? I would be most and for ever greatful I somebody could give me a hint. Thanx, Thomas -- This message posted from opensolaris.org
