Confused about some hdd stuff.

Hi again, this is beginning to quite a routine. New week and a new "need help post" from me.

Well, this time im referring to my problems with booting debian without any problems. And to sort this problem I need to fix some stuff with my disks.

One way of fixing this is really to comment out a line in my /etc/fstab and live it like that. But that makes my system 170gb smaller and that is really not a option.

The problems is that I have my /dev/hda divided into 2 partitions one /dev/hda1 and one /dev/hda5 (used to be /dev/hda2). Now, how can I make use of the /dev/hda5? And I want a ext3 system, like my /dev/hda1.

In before some comments about searching google and stuff I really gave it a go and tried some stuff of but without any success.
This is one of them:


debian:/home/andreas# tune2fs -j /dev/hda5
tune2fs 1.39 (29-May-2006)
tune2fs: Bad magic number in super-block while trying to open /dev/hda5
Couldn't find valid filesystem superblock.

Some infomation from my system:


debian:/home/andreas# df -a    
Filesystem           1K-blocks      Used Available Use% Mounted on

#/dev/hda2       /mnt/opt1       ext2    defaults        0       2
/dev/hdb5       /mnt/opt2       ext3    defaults,errors=remount-ro      0       1
/dev/hde        /mnt/opt3       ext3    defaults,errors=remount-ro      0       1
/dev/hdf        /mnt/opt4       ext3    defaults,errors=remount-ro      0       1
#/dev/hdc        /media/cdrom0   iso9660 ro,user,noauto  0       0

To sum it all up, I want to make use of /dev/hda5 (old /dev/hda2)

What about pasting the output of

# sfdisk -l /dev/hda

With that info we could help you.

Thanks a lot for that reply, maybe I might get this fixed tonight:)

Disk /dev/hda: 24321 cylinders, 255 heads, 63 sectors/track
Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0

   Device Boot Start     End   #cyls    #blocks   Id  System

If you are completely sure that /dev/hda5 is empty or you don't need the data anymore, just create a filesystem with

# mkfs.ext3 /dev/hda5

So then you can edit your fstab, changing /dev/hda2 for /dev/hda5 and uncommenting the line.

hehe, this is very weird. I did exactly this on some of the other disks on my system but i could not for the life of me remember the syntax and google gave me tune2fs -j /dev/hdX. So what is the difference?

Anyway, the syntax you provided did the trick and it got to work. Thanks a lot.

(feels a bit stupid)

tune2fs -j creates a journal in an ext2 filesystem, converting it to ext3.

But it has to be an ext2 filesystem first and your /dev/hda5 had no filesystem yet.

Everything is working like a charm. Uploading my backup to the disks and no troubles. Reboot works great as well. Although ssh login takes forever.

Although ssh login takes forever.

Probably unrelated. It might just be that your SSH server is trying to lookup the IP address of the connecting host - and that fails, after waiting for a while to timeout.

(When servers are slow to connect I always suspect DNS!)

Try adding host + IP address of your client to /etc/hosts on the server - and if that fixes it you'll know that was the cause.
