--M9NhX3UHpAaciwkO Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hi, I've just had a disk (pretty much) fail on me. I'd been suspect of it for some time now, but finally confirmed it with a reinstall to 5.2.1 when GEOM started removing it for me ;) Some more tests with smartmontools (http://smartmontools.sourceforge.net/) indicate read failures at the same position on the disk. This problem is made worse by the fact that this is a 100GB disk, part of a Vinum RAID-0 array (together with two more 120GB disks). I have managed to get my hands on a 123GB disk for backing up the data to to. I know I am going to have to use dd for this, but this is something I've never done before (short of a quick flirt with floppy images, etc.) Since GEOM has previously removed the volume when it hit the bad area I need to know if I can disable this to recover as much data as possible (some is better than none). If this requires installing 4 then that's how I'll have to do it. Basically I would like to ask -questions if anybody has any advice (other than ``you should have made backups'' -- I was in the process of buying a 3Ware RAID card for this purpose ;) as to how I should go about this. Anything at all... I'm pretty desperate at this point! Thanks very much, -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 |- --M9NhX3UHpAaciwkO Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQFAVKoCItq0KFQv7T8RAsnDAJ94WvWAmGm5uDF3tLtwGvcHX0i1KQCgnVZR lbdQMniJqcw4MQ/NlotFQSk= =Kw3u -----END PGP SIGNATURE----- --M9NhX3UHpAaciwkO--
