If this is the last sector of ad3, it certainly doesn't contain GEOM_STRIPE metadata, for whatever reasons. If this is really the right drive, you might try creating a temporary stripe array (with "gstripe create" instead of "gstripe label" of these two drives) and try running "dumpfs" on the array (or specifically partitions with UFS file systems on the array). If it finds the file system(s), run fsck on them. If it also passes, then delete this array and create it again with "gstripe label" to make it permanent. If dumpfs and/or fsck fail, you have at this point no way to reclaim your data. --------------enig9761C254A702A68E8DDDB4CA Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAknSb0UACgkQldnAQVacBchGjQCfZCZqVK8i1k7+tDE1sEpFSbLh UvUAmQErBrjonNKZKWu17kx/mAKeumen =v4AJ -----END PGP SIGNATURE----- --------------enig9761C254A702A68E8DDDB4CA--
