[SuSE Linux] Missing super block !!!!!
Hello all, First I wanted to thank everyone on this list who helps the newbies like me. (and for not being *too* brutal when we say the occasional uninformed thing, etc.) Now that I have buttered you up, I have a BIG PROBLEM. My system WAS working beautifully. But, in my attempts to install LILO, something has gone very wrong. Everything seemed to go flawlessly, LILO started, but then I got that "Unable to open initial console" error. So I tried out the fixes mentioned in the support database after someone pointed them out to me---they didn't work. I did get it down to a problem with recognizing the boot device (/dev/hda1). So I booted on to a Windoze boot floppy, figuring I would just do a "fdisk /MBR" to return to the original state. But, MY C DRIVE DISAPPEARED!!! I ran FDISK and it just says that the filesystem type for the first partition (C drive) is "unknown". Then from Linux, I ran Yast, which under partition info says the filesystem type for /dev/hda1 is "MS-Dos blah blah" (just like my D-drive which is fine), but when I choose a mount point (/dosc) and exit yast, it tells me that it can't mount /dev/hda1. It just says: RomperRoom:/home/chris # mount /dosc mount: wrong fs type, bad option, bad superblock on /dev/hda1, or too many mounted file systems So then I type: RomperRoom:/home/chris # dumpe2fs /dev/hda1 dumpe2fs 1.10, 24-Apr-97 for EXT2 FS 0.5b, 95/08/09 dumpe2fs: Attempt to read block from filesystem resulted in short read while trying to open /dosc Couldn't find valid filesystem superblock. So, it's seemingly hosed. What happened?

if this happens again you may try alt+f2

yea.. no problem there. when you run fdisk /mbr thats it. just fdisk /mbr you never get into the fdisk program. Win just identifies the area as unknown

You may need to add the filesystem type as in mount -ext2fs /dev/hda1
So then I type:
RomperRoom:/home/chris # dumpe2fs /dev/hda1 dumpe2fs 1.10, 24-Apr-97 for EXT2 FS 0.5b, 95/08/09 dumpe2fs: Attempt to read block from filesystem resulted in short read while trying to open /dosc Couldn't find valid filesystem superblock.

Id guess you just dont have lilo installed properly so maybe try this boot with a floppy-- before lilo kicks in type linux single root =/dev/hda1 initrd= or cahnge hda1 so its your / partition when you login run yast and look at boot configuration there. Set lilo back as it was before you probably could also just run lilo but yast makes it more graphical and you can be relitively sure it went onto the mbr good luck and have fun ;-) rob -- Bookmarks <A HREF="http://www.connix.com/~dizzy73/LBM.htm"><A HREF="http://www.connix.com/~dizzy73/LBM.htm</A">http://www.connix.com/~dizzy73/LBM.htm</A</A>> - To get out of this list, please send email to majordomo@suse.com with this text in its body: unsubscribe suse-linux-e Check out the SuSE-FAQ at <A HREF="http://www.suse.com/Support/Doku/FAQ/"><A HREF="http://www.suse.com/Support/Doku/FAQ/</A">http://www.suse.com/Support/Doku/FAQ/</A</A>> and the archiv at <A HREF="http://www.suse.com/Mailinglists/suse-linux-e/index.html"><A HREF="http://www.suse.com/Mailinglists/suse-linux-e/index.html</A">http://www.suse.com/Mailinglists/suse-linux-e/index.html</A</A>>
read in man lilo or the lilo howto any way your super block is backed up if it was ever replaced by lilo. as /boot/boot.0301 any way a cat /boot/boot.0301 > /dev/hda1 will do but find where I read this first so you understand and make sure you have the corect sector.

You can restore the superblock with "lilo -u" (uninstall LILO). This assumes you did not corrupt the superblock backup saved by LILO as /boot/boot.0301

/dev/hda1 is not an ext2 filesystem I assume. The mount command sometimes has problems autodetecting the correct filesystem type (when module stacks need to be loaded as it is with DOS), so try explicitly given the type: mount -tmsdos /dev/hda1 /dosc - To get out of this list, please send email to majordomo@suse.com with this text in its body: unsubscribe suse-linux-e Check out the SuSE-FAQ at <A HREF="http://www.suse.com/Support/Doku/FAQ/"><A HREF="http://www.suse.com/Support/Doku/FAQ/</A">http://www.suse.com/Support/Doku/FAQ/</A</A>> and the archiv at <A HREF="http://www.suse.com/Mailinglists/suse-linux-e/index.html"><A HREF="http://www.suse.com/Mailinglists/suse-linux-e/index.html</A">http://www.suse.com/Mailinglists/suse-linux-e/index.html</A</A>>

When you installed lilo, you were given the choice of installing it in one of three places, apparently you didn't install it on a floppy, which leaves either in / or the boot partition of the harddrive. Where did you install lilo? If you installed it in the boot partition, that may be the problem? Not really sure on that, I run os2's boot manager and so I installed lilo in /, but I do remember in my first attempt with rh, I made the mistake of installing it in the boot partition and ended up having to reinstall everything, but that was awhle back?

That sounds like the same thing that happened to me under rh. I had to delete the partition and reinstall everything to get it straightened back out:-( -- cya l8r Leon McClatchey leonmcclatchey@homemail.com Linux User 78912 (Win95 Box) - To get out of this list, please send email to majordomo@suse.com with this text in its body: unsubscribe suse-linux-e Check out the SuSE-FAQ at <A HREF="http://www.suse.com/Support/Doku/FAQ/"><A HREF="http://www.suse.com/Support/Doku/FAQ/</A">http://www.suse.com/Support/Doku/FAQ/</A</A>> and the archiv at <A HREF="http://www.suse.com/Mailinglists/suse-linux-e/index.html"><A HREF="http://www.suse.com/Mailinglists/suse-linux-e/index.html</A">http://www.suse.com/Mailinglists/suse-linux-e/index.html</A</A>>
