Hi, I have been successfully running a RAID5 for a long time now. It the last week the computer running the RAID crashed, probably because of too high temperature. The disk configuration is as follows: /dev/hda1 - ext2 - /boot /dev/hda2 - swap /dev/hda3 - reiserfs - / /dev/hdc1 - linux raid auto /dev/hde1 - linux raid auto /dev/hdg1 - linux raid auto The three RAID partitions run as a RAID5 (/dev/md0) with LVM on top (/dev/raid5storage/lvol1) and the ext2 filesystem. After the crash I could not boot linux. After some repairing I got the root partiotion boot (some shared library was damaged). The system booted up, the RAID reconstructed and I could successfully e2fsck /dev/raid5storage/lvol1. The I decided to make a partiotion on the first disk to back some things that are on the RAID up. I did # fdisk /dev/hda :n (new) ... (/dev/hda4, 55GB) :w (write and exit) # The partition did not show up under /dev/hda4 immediatly, so I rebooted the system. After that the RAID started running the reconstruction again and e2fsck told me: /dev/raid5storage/lvol1: UNEXPECTED INCONSISTENCY; run fsck MANUALLY /dev/raid4storage/lvol1: Block bitmap for group 141 is no in group (block 32768) fsck.ext2 /dev/raid5storage/lvol1 failed (status 4)! run it manually! I did that: # e2fsck /dev/raid5storage/lvol1 Group descriptors look bad... trying to backup blocks... e2fsck: Bad magic number in super-block whily trying to open /dev/raid5storage/lvol1 The superblock could not be read or does not describe a correct ext2 file system. ... I have no idea why the superbock is damaged, since I did not repartition any of the disks in the RAID. Can somebody please help me? I need to recover the data. Thanks in advance.
