Okay - thanks for your reply..sorry about top posting..i am in
gmail..and it does what it wants.
So let me answer your questions:
>why do you think this? What evidence tells you this? have you looked
> at /proc/mdstat?
i looked into /proc/mdstat -- it has inactive raids.
I have tried to re-correct the problem by removing and adding to the raid.
it has not helped. I get : Block bitmap for group 1664 not in group
(block2195960)!
EXT3-fs: group descriptors corrupted!
Mounting /dev/mapper/vg_main-lv_root on /root failed: Invalid arguement.
then..there is a whole mess of failed scripts.
the system boots..it just goes into Busybox.
It never mounts any of the filesystems. the /boot filesystem seems to
be okay..because i create a directory and mount it there.
and i am able to see all the other kernels and grub directory too.
the issue comes when i try to mount my /dev/md1 which has / and /home
and all the other filesystems.
that has the lvm2 volume groups.
I think i need to get the error "Group descriptor corrupted" error fixed, yes?
how do i get past that?
i am able to boot into rescue mode and execute commands.
Please be more specific iwth the commands you want me to execute.
thanks
mjh
