 |
|
Hi
I was going to shrink my root partition (hda1) to create an home one. I started knoppix and played with resize2fs and fdisk. I managed to get 20Go, deleted the swap partition (old hda2) and created a new ext2 one (new hda2). i omited to swapoff -a before deleting the old swap - this is maybe my error. But i managed to mount my hda2 after that and styarted to backup my home directory. The partition was quickly full, i restarted to shrink my root partition and filesystem; then enlarged my hda2 partition, but when i would resize the filesystem, i got this error :
| Code: |
root@ttyp1[mnt]# resize2fs -p /dev/hda2
resize2fs 1.35 (28-Feb-2004)
resize2fs: Bad magic number in super-block while trying to open /dev/hda2
Couldn't find valid filesystem superblock.
|
I tried to e2fsck with an equivalent error. And i couldnt mount it anymore.
I dont know what i did to make that happen.
Ask me whatever, my consoles are still open, i can send you all commands i typed.
thx

If I had to guess, I'd say that the MBR hasn't been updated. In otherwords, it doesn't know you've resized the partition. Might have been caused by deleting the swap partition. I would have left that alone. You might just have hosed those partitions completely at this point. I hope you at least backed up your home directory before you resized. I don't imagine it would make any difference, but have you tried booting up to the Gentoo live CD?
You'll probably have to start from scratch. Good luck.

Im currently using knoppix, so the live cd wont be different, i guess. I didnt backup anythingthing and thats the problem. I need at least my docs and mails. My datas are still written on some part of the disk and not damaged. It should be a way to get them back. The worse thing is that I couldnt mount the partition again whithoiut having done anything on it 
But your right, if i dont manage to get them tonight, ill have to restart from scratch tomorrow

Pehraps you can try recreating only the superblock and group descriptors: | Code: | | # mke2fs -S /dev/hda2 |
Then perhaps you would want to fsck it to be safe:Hth!

I didnt know this options.
It was the best thing to do i gues, thx for your reply.
Anyway, from the output of e2fsck, i think my data are really lost.
Ill restart everything from scratch with a stage 1 install. Hopefully, there some data on my root partition i cant backup 
thx
