fstab wiped out

[run1206]

ok, so while trying to get my printer to work i tried various .deb files while trying to use other drivers. For some reason my fstab file was wiped and the the only thing showing is the usbfs filesystem

my question: Is there any way to "recompile" the original list that i had? Is there any place where i may be able to re-list all the filesystems that were on /etc/fstab?

(I can still restart/shutdown Linux and reboot fine, but i know I need that file with the original list of filesystems i had before.)

any suggestions would be great, thanks in advance.

If you can still boot Ubuntu, then there has to be /etc/fstab or the system won't know where to mount what.

What's the output of this command from a terminal?

ls -la /etc/fstab*

[run1206]

run1206@run1206-laptop:~$ ls -la /etc/fstab*
-rw-r--r-- 1 root root 112 2009-03-15 16:32 /etc/fstab
-rw-r--r-- 1 root root  71 2009-03-15 16:31 /etc/fstab~
-rw-r--r-- 1 root root  43 2009-03-15 15:31 /etc/fstab.lexmark-z600.bak

is there any way that i might use mtab to fill in the missing filesystems?
i see most of them are there...

cat /etc/fstab

Nevermind - taurus has it covered. If fstab is empty, take a look at the contents of fstab~ and you might be able to recover that file.

[run1206]

run1206@run1206-laptop:~$ cat /etc/fstab
# 	<file system> 		<mount point> 		<type> 		<options> 	<dump> 		<pass>
	proc 			/proc 			proc 		defaults 	0 		0
run1206@run1206-laptop:~$

and fstab~...

run1206@run1206-laptop:~$ cat /etc/fstab~
# 	<file system> 		<mount point> 		<type> 		<options> 	<dump> 		<pass>
run1206@run1206-laptop:~$

[taurus]

cat /etc/fstab~
cat /etc/fstab.lexmark-z600.bak

[run1206]

run1206@run1206-laptop:~$ cat /etc/fstab~
# 	<file system> 		<mount point> 		<type> 		<options> 	<dump> 		<pass>
run1206@run1206-laptop:~$ cat /etc/fstab.lexmark-z600.bak 
usbfs			/proc/bus/usb		usbfs	devgid=14 0 0
run1206@run1206-laptop:~$

the only one showing is the usbfs...

anyway how i can manually put the filesystem back into fstab?

You need to know the UUID's for all the partitions.

sudo fdisk -l
sudo blkid

Then, your /etc/fstab would look something like

proc            /proc           proc    defaults        0       0

UUID=qwer1234asdf5678zxcv  /  ext3  relatime,errors=remount-ro  0  1
UUID=1234qwer5678asdf90  none   swap  sw  0  0

/dev/scd0       /media/cdrom0   udf,iso9660 user,noauto,exec,utf8 0       0

[run1206]

thanks for the blkid command...
here's what i get.

run1206@run1206-laptop:~$ sudo blkid
/dev/sda1: UUID="2A08D775E49BED2A" LABEL="PQSERVICE" TYPE="ntfs" 
/dev/sda2: UUID="3C9051F19051B25E" LABEL="ACER" TYPE="ntfs" 
/dev/sda3: UUID="E460B8DC60B8B720" LABEL="DATA" TYPE="ntfs" 
/dev/sda5: UUID="c6853b2c-6e0b-40b2-ba6a-92ed9b86c6d5" TYPE="ext3" 
/dev/sda6: TYPE="swap" UUID="5b5cd6e0-e2c0-4f79-96ce-912d82e5ce7f" 
/dev/sdb1: LABEL="My GS Drive" UUID="780E-9E13" TYPE="vfat" 
run1206@run1206-laptop:~$

my fstab thus far is the attached file..
