Mounting a partition

1veedo · 12-19-2004, 04:58 PM

So I'm trying to mount a (I assume ext3) partition.

Code:

[root@localhost azevedo]# mount -t ext3 /dev/hda4 /mnt/hda4
mount: wrong fs type, bad option, bad superblock on /dev/hda4,
       or too many mounted file systems

I dobot I have too many because the only 'other' partition is hdb1 which is an ntfs filling system. Ironically I got that one mounted but cannot get a Linux filling system recognized.

Code:

Disk /dev/hda: 40.0 GB, 40020664320 bytes
255 heads, 63 sectors/track, 4865 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hda1   *           1        1657    13309821   83  Linux
/dev/hda2            1658        2549     7164990   83  Linux
/dev/hda3            2550        2676     1020127+  82  Linux swap
/dev/hda4            2677        4865    17583142+  83  Linux

Disk /dev/hdb: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hdb1   *           1        9729    78148161    7  HPFS/NTFS

It's there. Another question though: Can I add hda2 onto hda1? That was going to be for windows but I reformated it to Linux.

do you have ext3 support in the kernel? (you probably do)
is the partition defined in /etc/fstab.

Most importantly, since you don't seem sure on whether it's ext3 or not, just issue

Code:

mount /dev/hda4 /mnt/hda4

and make sure the mount point exists

Besides qtparted that might do the trick for you, I'm sure there are command line tools to resize partitions. You'll probably have to erase hda2 and then resize hda1 to occupy the empty space... Someone else can probably give you more info on this one.

When I installed Linux I put it on ext3 so I assume so. fstab gave me "bash: /etc/fstab: Permission denied" and I'm in root. However, the partition does show up with /sbin/fdisk -l.

My version, I guess, requires that I specify a filling system with the mount command. I have tried it with ext2 though:

Code:

mount -t ext dev/hda4 /mnt/hda4
mount: fs type ext not supported by kernel

I think it is ext3 sense hda1 is and fdisk -l says Linux for both partitions. Is there any other way I can find out what the partition is?

edit:
ext2 gives the same error

you could try cfdisk /dev/hda, it shows what filesystems you have. But be careful not to accidently delete a partition (it's curses-fdisk). You might have a reiserfs-partition.

/etc/fstab is a config file. Issue the following command to edit it:

Code:

nano -w /etc/fstab

You should have something like this there

Code:

/dev/hda4               /mnt/hda4     ext3        noatime,users,exec      0 0

enter that line and then you should be able to mount the partition by simply entering:

Code:

mount /mnt/hda4

Code:

# This file is edited by fstab-sync - see 'man fstab-sync' for details
LABEL=/                 /                       ext3    defaults        1 1
none                    /dev/pts                devpts  gid=5,mode=620  0 0
none                    /dev/shm                tmpfs   defaults        0 0
none                    /proc                   proc    defaults        0 0
none                    /sys                    sysfs   defaults        0 0
LABEL=SWAP-hda3         swap                    swap    defaults        0 0
/dev/hdd                /media/cdrecorder       auto    pamconsole,fscontext=sy$
/dev/hdc                /media/cdrom            auto    pamconsole,fscontext=sy$
/dev/fd0                /media/floppy           auto    pamconsole,fscontext=sy$

I dont think that looks very good. How do I use cfdisk? I've tried several things and it just goesto the next line doing nothing.

Code:

[root@localhost azevedo]# #cfdisk P /dev/hda4
[root@localhost azevedo]#

just add the fstab entry I supplied to your fstab-file. I don't think there's anything really wrong with what you have there now. Just leave the rest as it is.

just write:

Code:

cfdisk /dev/hda

that should get you to a page where you can see all the partitions on hda.

And, um...I really dont know how to do that. I found this:
http://www.humbug.org.au/talks/fstab/fstab_options.html
...but none of it is actually making any sense to me.

code:

cfdisk /dev/hda

I tried that but:

Code:

[root@localhost azevedo]# cfdisk /dev/hda
bash: cfdisk: command not found

I think if I can add the fstab entry I'd be fine though.
