Hi Nigel, thanks for taking the time, I appreciate it. Yes I have posted my question/problem to zfs-discuss and various other forums, but haven't received a lot as yet.
Now here is the output of zpool status in english (I should have thought about it before to just change the language setting :) zpool status -xv pool: usbDisk state: FAULTED status: One or more devices could not be used because the the label is missing or invalid. There are insufficient replicas for the pool to continue functioning. action: Destroy and re-create the pool from a backup source. see: http://www.sun.com/msg/ZFS-8000-5E scrub: none requested config: NAME STATE READ WRITE CKSUM usbDisk FAULTED 0 0 0 corrupted data c5t0d0s0 FAULTED 0 0 0 corrupted data The labels 'usbDisk' are from my original pool on Solaris 10/Ultra25 the labels 'WD' are from my attempt to access the disk on Solaris 10/PC. So far I haven't done anything to the disk (I think) in terms of recovery because I'm very vary to destroy/corrupt even more. What I tried was to access the disk on a Nevada/PC system which at least was able to get the labels ('WD') but couldn't get the zfs in the pool. Now the disk is back at my Solaris 10/Ultra25, so the output I sent is taken from Solaris 10. For the time being I don't have access to Nevada since I'm doing an 'undelete' on my PC in the hope to recover the original data, in case the zpool/zfs recovery is not possible.
