You ran "zdb -l /dev/dsk/c7t5d0s2" which is not the same as "zdb -l /dev/dsk/c7t5d0p0" because of the default partitioning. In Solaris c*t*d*p* are fdisk partitions and c*t*d*s* are SMI or EFI slices. This why label 2&3 could not be found and can be part of the problem to start. Everything in /dev/dsk and /dev/rdsk is a symlink or directory, so you can fake them out with a temporary directory and clever use of the "zpool import -d" command. Examples are in the archives. -- richard > > if anyone could help me use zdb or mdb to recover my pool > I would very much appreciate it. > > I believe the metadata is corrupt on my zpool > > > -- > > Sam Fourman Jr. > Fourman Networks > http://www.fourmannetworks.com > _______________________________________________ > zfs-discuss mailing list > zfs-discuss@opensolaris.org > http://mail.opensolaris.org/mailman/listinfo/zfs-discuss -- Richard Elling rich...@nexenta.com +1-760-896-4422 ZFS and NexentaStor training, Rotterdam, July 13-15, 2010 http://nexenta-rotterdam.eventbrite.com/ _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
