Hey, This is not really a recommended solution, but I have had some success in the past with manually re-creating lvm partitions and reiserfs fs with the exact specs of the original directly over the messed up disk and used reiserfs recovery tools. Some file names and directories are remembered and others aren't I'm not sure of the rhyme or reason to it, but it worked when I hosed my overly complicated raid5/lvm/reiser setup and I didn't lose too much. If you have a spare disk, take a disk image before you start messing with it. cheers, Owen. p.s. By overly complicated I mean I was fiddling with various ways of using md, lvm, hardware raid, etc and the hodge-podge result (4 disks in 4 single disk jbod arrays through a raid card, 11 md raid5 arrays using ~40GB slices, then lvm over the top of it all) inadvertently became filled to a point where I couldn't wipe and make it simple again. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
