Hi!
I'm new to this list... and I have a problem (or rather, It's my friend's problem). The background: I installed Fedora core 3 for him on an via epia machine. I wasn't really paying attention when I did the install for him and let the install program handle the partitioning which led to fedora being installed with lvm "partitions" (id: 0x8e). The day after when he had started using his new 'puter it froze (hard) so he had to push the "button" (there's no reset - only poweroff on the box). When trying to boot into FC3 again it boots the kernel (so apparently the boot partition is ok) but when it tries to launch init (on root partition) it panics saying:
ext3_underscore_descriptors: block bitmap for group 128 not in group (block 0)!
Group descriptors corrupted.
So booting with the FC3 install cd rescue mode and doing a fsck does not help, since it (fsck) complains about superblock corruption. From what I and my friend understands lvm is a sort of linked list of physical volumes (harddrives) containing the ext3 filesystem (i.e. it encapsulates the filesystem). Could it be that the ext2 tools supplied on the disc is not lvm-aware so that it doesn't recognise the filesystem? Or is it possible to "extract" the ext3 data (or remove the lvm data on the partition thus converting it to a "clean" ext3 or ext2 filesystem) somehow? What we're really interested in is rescuing some data on the drive since he (without thinking) moved some data from another computer to this epia 'puter (i.e. he erased his only backup). This is a situation where H.Simpson would say "doh"! Another possibility would be to re-create the superblock information in the ext3 but I don't know how to access it. Any help would be very much appreciated... TIA!
Best regards
Peter K
