Corrupt fstab

pooky2483 · October 21, 2013, 5:32pm

I have tried to edit the fstab of my original Ubuntu12.04 but somehow it got corrupted!
[spoiler]s# /etc/fstab: static file system information.

Use ‘blkid’ to print the universally unique identifier for a

device; this may be used with UUID= as a more robust way to name devices

that works even if disks are added and removed. See fstab(5).

Now, it looks like when I edit it in Kubuntu and then try to save it, it duplicates itself???

Why is it doing this and how can I fix it?

Now, it looks like when I edit it in Kubuntu and then try to save it, it duplicates itself???

That could be because you do not have the right to edit that file. Hence it goes into a 'Save As' mode. Try to be root when you open the file.

pooky2483 · October 21, 2013, 8:14pm

While in Dolphin, I press [F4] which brings up a small terminal window at the bottom of Dolphin with the current path to the folder I’m in where the fstab for Ubuntu12.04 (original install) is, but it just brings up a blank file.
I try and edit it with

gksudo kate fstab

So, I have to just open it by clicking on it and telling it to open in Kate.
After editing it, Kate comes up with;

pooky2483 · October 21, 2013, 8:31pm

When I said it duplicates itsef, I meant inside itself,not a backup.

Mark_Greaves_PCNetSp · October 21, 2013, 8:47pm

Try editing it from an Ubuntu LiveCD … to rule in/out an issue with kate.

Anything called “kate” was bound to get uppity every now and again

pooky2483 · October 21, 2013, 10:20pm

Tried but no joy!
I tried editing the lines out at first but the problem was still there so I decided to remove the lines completely but that still didn’t solve the problem, one of which was the 3TbHd’s. So I tried switching off the Hd’s then booting back up but there is still a problem as it still boots to the recovery screen (the colourful one with the menu).

pooky2483 · October 21, 2013, 10:32pm

Don’t know if this is anything but I just opened fstab again and at the top it said ‘The file was not closed appropriately. Do you want to recover the data?’

Why is it saying that when I edited it OK and then saved it no problem while using a ‘Live CD/DVD’?

Mark_Greaves_PCNetSp · October 21, 2013, 10:37pm

Dunno … what did you open it with when it gave that warning ? … kate ?

pooky2483 · October 21, 2013, 10:38pm

Yes, Kate

Mark_Greaves_PCNetSp · October 21, 2013, 10:41pm

If it’s working … tell kate NO

pooky2483 · October 21, 2013, 10:48pm

Just booted into the other Ubuntu12.04 I installed when I created the multi-boot and used gedit to look at the fstab and I didn’t get the error warning.
So I still can’t understand why it won’t boot properly?

Mark_Greaves_PCNetSp · October 21, 2013, 11:53pm

What makes you think it was fstab in the first place ?

Have you run fsck on the broken system/partition ?

pooky2483 · October 22, 2013, 12:31am

I was messing with fstab, adding the 3TbHd’s to it.
How do I run ‘fsck’?

chemicalfan · October 22, 2013, 8:44am

So, what actually happens when you try to boot each OS now?

pooky2483 · October 22, 2013, 11:36am

Not run fstab on the original 12.04 drive as not sure how.
Other OS’es fine. When I select the original OS loads of info flies up the screen, too fast to copy, then it shows the screen as mentioned above.
I can’ boot into the OS as it keeps doing that.

Any idea if it keeps a boot up log that I can copy the info from?

Mark_Greaves_PCNetSp · October 22, 2013, 11:47am

too fast to copy, then it shows the screen as mentioned above.

What screen mentioned above ?

Are you saying when you select “Ubuntu 12.04” at the GRUB menu, it actually boots (Ubuntu 12.04 (recovery mode)) instead ?

pooky2483 · October 22, 2013, 12:39pm

Yes, some kind of recovery mode, one where there’s a colourful menu, GUI style.

In the OS that controls GRUB … what’s the contents of:

What is listed and in what order at the GRUB menu ?
What is the output from:

sudo blkid

Which partition is the broken Ubuntu on ?
