I issued the command swapon /dev/sda3 and it looks like it is a swap file but fstab still shows it as ext4.

r@r:~$ sudo swapon -s
Filename Type Size Used Priority
/dev/sda3 partition 12287996 0 -1
r@r:~$

I am also having problems printing now because of a lack of space in my tmp file.

Why can't I find an fstab file under /etc? I have show hidden files enabled.

Thank you for sticking in there.

All you have to do is change this UUID
To this UUID from blkid
Then either reboot or do swapon

A swap partition doesn't have a file system - such as ext4.
Try:- That last line is to edit the mount of your swap partition, it should be something like:-
The common editing operations such as CTRL+O = save are displayed on the bottom of the window.

Note that the UUID might/will(?) get changed - to discover what it has changed to, useBTW You need root access (or sudo) to edit all files in /etc

To edit fstab

I had problems using nano. Now my laptop boots to a login prompt and tells me No directory logging in with home=/. When I try to edit fstab it tells me that I am read only when I try to save it.

When I issue a command like sudo cat /etc/fstab I get a message
sudo: unable to open /var/lib/sudo/r/tty1: No such file or directory and then it proceeds to give me the results of the command.

How can I edit fstab?

Thank you

Try this http://askubuntu.com/questions/17573...-as-read-write

I was able to recover by booting from a usb, mounting sda1, and editing fstab. When I used nano it did not open full screen and I managed to truncate the permissions off somehow. I think I have the wrong UUID for my swap file. I think it changed in all my rebooting. The blkid command probably gave me the correct UUID.

Then if you have that type of problem run blkid, then edit fstab according to output.

I edited fstab to match blkid but still did not seem to have swap file until issuing swapon command.

Does it maintain swap from reboot?
edit
sda3 in fstab is wrong format, You only needed to replace UUID in fstab not the whole line I marked the UUID in red. That has change though, so put it back in original format & change to new UUID.

With the changes I made I wan't sure just what fstab should look like so I cloned fstab off a different laptop and updated the UUID's. The swap file shows up now.

You don't need on a swap partition.
If it has errors, there is no point in remounting it as read only.

My /var/log file is taking up 15 Gb. 6 Gb of that is my syslog file. Here is a sample of the messages:

Feb 11 20:41:28 r kernel: [556124.707960] mei_me 0000:00:16.0: reset: unexpected enumeration response hbm.

From Googling it I think it is a bug and I am either suppose to blacklist the module mei_me of stop it in the bios.
I will see if I can find out how to blacklist it. I also noticed that the log goes back to the 11th.

How would be the best way to clear the logs?

Thank you

I removed the errors=remount-ro from the swap file and restarted.

Thank you
