I guess, this should work ... but make sure, that you do the copy operation on another system, otherwise the LVM stuff could/will be irritated by two diffent disks with the same signature (after copying over) > The other option I can think of is remove that drive from the volume and then > remount it, but that would mean a loss of everything that is one the failing > drive, plus I am not sure how reiserfs works with large chunks of its file > system removed like that. I wouldn't do that, neither with reiserfs nor with any other unix filesystem ... only as last escape if you disk is completely unreadable ... anyway, if possible make a copy of ALL disks involved before you do any fscking so you can go back and try any other approach ... best, Herbert > thanks > > bjz > > _______________________________________________ > linux-lvm mailing list > linux-lvm@sistina.com > http://lists.sistina.com/mailman/listinfo/linux-lvm > read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/ _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
