Disc/partittion problem after upgrading from 13.0 to 13.1


I have two harddrives in the computer and both are the old P-ATAs.

When upgrading to the new Slackware 13.1, I had no problems with the first hardrive, but I get some problems with the second one.


This is my fdisk -l
Code:
root@Muspellsheim:~# fdisk -l

........

and ls /dev/sdb* give me this
Code:
root@Muspellsheim:~# ls /dev/sdb*
/dev/sdb  /dev/sdb1
mounting /dev/sdb1 gives me an error
Code:
root@Muspellsheim:~# mount /dev/sdb1 /mnt/filmer/
mount: /dev/sdb1: can't read superblock
I haven't had any problems with the harddrive until upgrading to 13.1, so my guesses there's some driver problem with the new kernel. There are three partitions on the harddrive (sdb1), I can see all three on fdisk -l, but one partition only when trying to list the partitions with ls /dev/sdb*

Do you guys have any tips for helping me out with this problem?

"Can't read the superblock" is usually a sign of filesystem damage. You might want to see what xfs_check tells you about /dev/sdb1

Also read the xfs_check man-page as it gives you some detail on how to recover from damage.


One thing I do notice is that your /dev/sdb1 has the boot ('*') flag set. What concerns me about this is that if I remember rightly, xfs filesystems start from block 0, and if you install a bootloader to an xfs partition, it'll overwrite the first few blocks of the filesystem. I hope that's not what's happened here. You can check whether that's the case with:
Code:
dd if=/dev/sdb1 bs=512 count=1 | hexdump -C
If you see the string 'LILO' on the first line of the output, then that's probably what's happened.

I'm happy there's no LILO on the first line, but the other lines doesn't look too promising either.

Just to decide wether it's a Slackware 13.1 problem or a filesystem failure, I booted the old Slackware 13.0 installation CD. I was able to mount all three partiotions, list the directories and files with no errors what so ever. This makes me pretty sure there's no filesystem failure, but rather a driver problem in Slackware 13.1.

When upgrading to 13.1 there were some new changes, where I had to rename my harddrives from hda and hdb to sda and sdb. I also had to delete /etc/udev/rules.d/70-persistent-cd.rules according to CHANGES_AND_HINTS.TXT, but this is related to cdrom-devices and not harddrives...

Well I'm glad it's not the lilo issue. And as you say going back to 13.0 the filesystem is still there so it's clearly still intact.

If you're sure that sdb is indeed the correct device name for the drive after the hd-->sd renaming then I don't have any other ideas. Does running "blkid" from your 13.1 system show anything that might suggest a naming mismatch?

blkid lists only one partiton on sdb, and that's the sdb1
/dev/sdb1: UUID="a81ab032-35cf-4375-939b-65e5a9304e9c" TYPE="xfs"

It says XFS which is correct.

Can you post the output(in full) of the following please

cat /proc/partitions

ls -l /dev/sd*

Looks like fdisk is the only tool being able to see sdb2 and sdb3

Yes, that's most definitely 'weird'. I was curious to see whether the major/minor numbers were ok, but that all looks right. Even if udev was getting it wrong, I'd have expected your missing partitions to show up in /proc/partitions.

The only time I've seen anything like this was on a very large disk where the partitions were going past the 2TB partition size limit, but from the sizes on your fdisk, that doesn't look to be the case here either.

Anything unusual show up in your 'dmesg'? I'm pretty much out of ideas at this stage.

afterthought:
If you're still using the 'huge' kernel, it might be worth trying to swap to 'generic' + initrd and see if that helps.

I had the same problem: http://www.linuxquestions.org/questi...13-1-a-812293/ and finally got it: My harddisk was jumpered as a slave and i just removed the jumper.

You are right, GazL. The disc is probably 300GB and each partition about 100GB.

I'm trying to post the interesting parts from dmesg

Especially the Ğattempt to access beyond end of deviceğ caught my eye. But perhaps nothing new, when fdisk thought the disc was no larger than 38GB.

Thanks for sharing your solution syvy. sdb is my secondary disc though (slackware installed on sda), but I'll surely check my bumpers. Strange this issue didn't affect the older versions of Slackware.

I think the new libata subsystem is handling those things different.

Code:

Well, there's the cause. For some reason the kernel on slackware 13.1 thinks your disk is only 32ish GiB so it disables the partitions it thinks go beyond that. I've never seen that before. I have no idea why it's happening.

You are absolutely right. Removing the jumper from sdb solved the problem.

Thanks, syvy and GazL.
