X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 16 Mar 2004 02:00:14 -0000 --EVF5PPMfhYS0aIcm Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hi, I had a failed disk in my RAID-0 Vinum array. This was a physical disk problem and in an attempt to recover as much data as possible I dd'ed it to another disk (dd if=3Dad3 of=3Dad1 bs=3D8192 conv=3Dnoerror). This has mostly gone fine (bar the I/O errors that were to be expected) and I can actually start vinum and mount the RAID-0 array with no trouble (Vinum reports no errors I can see). I don't really know how I can test the integrity of files from the replaced disk... I attempted to fsck the volume before I mounted it but I first had to restore the superblock for the volume (tunefs -A /dev/vinum/data), which worked fine. However (and this is my real problem), fsck_ufs /dev/vinum/data gives the following message: ** /dev/vinum/data cannot alloc 4316869296 bytes for inphead ***** FILE SYSTEM STILL DIRTY ***** Searching about doesn't reveal much of any use -- Google Groups has a few of these errors for Solaris, so I assume it to be a fairly ``generic'' UFS error (?) Any suggestions what I can do now? I am expecting corruption on my array but I thought some corruption was better than nothing at all. Am I way off thinking that I can do this? I've not included many specific details here because I don't know if they are relevant. Just ask if I've missed anything and I'll provide it right away. Thanks a lot, -lewiz. --=20 I was so much older then, I'm younger than that now. --Bob Dylan, 1964. ------------------------------------------------------------------------ -| msn:purple@lewiz.net | jabber:lewiz@jabber.org | url:www.lewiz.org |- --EVF5PPMfhYS0aIcm Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQFAVl+gItq0KFQv7T8RAryLAJwJp8NbzZJvZnbYWel4IyGL/dJ7swCeKwuu 1ZGczCzvipmSwhJx66CfC4Q= =y2k5 -----END PGP SIGNATURE----- --EVF5PPMfhYS0aIcm--
