How to fstab

[XStatic64]

Hi all,

I have ubuntu installed on a 120GB IDE HDD, with 2x 200GB Sata drives spare that i wish to mount.

I've gone ahead and created/formatted the partitions as you can see below:

Disk /dev/sdb: 200.0 GB, 200049647616 bytes
255 heads, 63 sectors/track, 24321 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1       24321   195358401   83  Linux

Disk /dev/sdc: 200.0 GB, 200049647616 bytes
255 heads, 63 sectors/track, 24321 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000

   Device Boot      Start         End      Blocks   Id  System
/dev/sdc1               1       24321   195358401   83  Linux

And I've tried to mount the drive(s) via:

mount -t ext3 /dev/sdb1 /mnt/files

Which returns:

mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

I've also tried adding the entry in fstab but of course that doesn't work if the drives wont manually mount..

Any suggestions?

Please forgive me if I'm a moron, new to linux .

I do not see any obvious problem.

If you do not have an entry in fstab, you need to mount with sudo.

Make a mount point first.

Are your partitions formatted ?

sudo mkdir /mnt/files
sudo mount /dev/sdb1 /mnt/files

Also, right after attempting to mount, what is the output of this command :

dmesg | tail

Thanks for this post, I'm gonna bookmark it. I'm pretty sure it'll come in handy

I want to change the default label for my mounts as they are being displayed as 10.7gb media, and I would like more meaningful names. Tried using tune2fs and e2label but I get a "Couldn't find valid filesystem superblock" error.
Seeing as they are already mounted, could I just edit fstab and add some labels?

EDIT: Okay got the ext3 partition sorted, now ntfslabel can't access my windows partition as it 's already mounted. I sudo nautilus unmounted it, but then ntfslabel is denied access to it. Anyway to change an unmounted NTFS partition's label?

EDIT 2: No matter, managed to unmount it from terminal, and then used PYSDM to create a label for it. Job done.

Could you tell me how you did it?
Because I have similar problems:

Pretty sure it was simply:

sudo e2label /dev/sdax label

where sdax refers to your partition. and label is what you want to call it. If you run it without sudo then you get the previously mentioned error. You'll need a reboot to see the changes take effect, and I don't think you need to edit fstab as your partitions are already mounted.

If it's still giving you problems after entering the command and rebooting, then try installing PYSDM, a nice little app which allows you to to mount and label drives/partitions. It basically edits fstab on your behalf, and it seems to work for me.

Get it from synaptic, or type:

sudo aptitude install pysdm

Thanks A$h X, but I guess my problem is different.
I just wanted my ext3 partition mounted as a unremovable drive (without the desktop icon).

Hi, this post is great, thanks a lot!

I'm a bit stuck on one thing though. I have a FAT32 partition I've managed to get automounting, however it's not letting me write data to it because the owner is root. This is the fstab entry for it:

#/dev/sda2
UUID=4812-2CE3 /media/SHARED vfat auto,users,rw 0 0

What should I change to allow read/write access to anyone logged in? I'm on Hardy if that's of any relevance...

Thanks a bunch

Try this entry :

                              #/dev/sda2
UUID=4812-2CE3  /media/SHARED  vfat  auto,users,uid=1000,gid=100,dmask=007,fmask=137  0 0

@bodhi.zazen - thanks a lot! That seems to have fixed it (after I rebooted).
