The system paniced with a message very similar to the one reported in http://unix.derkeiler.com/Mailing-Lists/FreeBSD/current/2009-05/msg00181.html . Seems, that the on-disk structure is damaged, since the identical panic happens even when I try to import into a fresh -CURRENT with its newer ZFS code. Is there any chance to recover my data? I have copies of some critical information, but no easily restorable complete backups and thus I´m very interested in getting (most of) this pool working again ... Any ideas or help? Thanks in advance! STefan
