There are 4 labels on a zfs-labeled disk, two at the start and two at the end. Have all been overwritten? > Unfortunately I don't have a zpool.cache either. > > Is there a way to reconstruct the labels using the infomration from the 3 > valid disks? The simple answer is: no, without labels those disks are toast. The more complicated answer: the labels contain the root block pointer to the root of the filesystem tree on the given device. Without it you don't know where to start looking for many of the top-level structures needed to begin making sense of the data on the disk. -- Saso _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
