[SOLVED] Cannot "mount swap"

Hi

I cannot mount my swap partition! It stopped working some time ago (I don't know when exactly, I just saw this now).
When I try to mount it manually, I receive this error message: "Unknown filesystem type 'swap'".

Here is my fstab (I'm synchronized with the stable repo):

# <file system>        <dir>         <type>    <options>          <dump> <pass>
none                   /dev/pts      devpts    defaults            0      0
none                   /dev/shm      tmpfs     defaults            0      0


/dev/cdrom /media/cdrom   auto    ro,user,noauto,unhide   0      0
/dev/dvd /media/dvd   auto    ro,user,noauto,unhide   0      0
UUID=1137358e-63f7-4d63-a98a-34d03ac5be0b /boot ext2 defaults,noatime 0 1
UUID=1ce2a0be-3cb7-45f1-aef9-83214ceb3d6a swap swap defaults
UUID=8e33d82d-b7bb-4ea4-aa58-99806a705328 /home reiserfs defaults,noatime 0 1
UUID=954fcd95-c5cc-452d-bd1c-efb8b76aeb22 / reiserfs defaults,noatime 0 1

Thanks in advance.

Re: [SOLVED] Cannot "mount swap"

Linux does not permit mounting swap...only filesystems are mounted with the mount command.

Re: [SOLVED] Cannot "mount swap"

What does the output of `free -m` show you in the "Swap" row?

You 'mount' swap by using the `swapon` command. Have a look at the man page to find out more

man swapon

Re: [SOLVED] Cannot "mount swap"

Actually, I still can't solve it. The problem is that the swap partition isn't activated by default, ie, swapon -a doesn't work.

I've tried editing my fstab, without success (man fstab doesn't gives much inf about this).

Re: [SOLVED] Cannot "mount swap"

My swap broke after I unsuccessfuly tried to hibernate so I run mkswap /dev/sdaX for x being my swap partition. And then swapon -a and it works. However I don't know whether the disk UID changes after making a new swap file system.(I got rid of BY-UID things in my configs since /dev/sdaX is so much easier to read.)

Re: [SOLVED] Cannot "mount swap"

You are using the UUID to mount the partition, have you tried using the /dev/sd? entry to mount the drive instead?

My fstab entry for swap reads the following:

/dev/sdc3 swap swap defaults

Re: [SOLVED] Cannot "mount swap"

Thanks for the suggestion, it worked.
I was strange, because it was working before!

Re: [SOLVED] Cannot "mount swap"

Wow even I accidentally disabled swap somehow and I tried everything, but it would not work ( http://bbs.archlinux.org/viewtopic.php?id=52252 ) . But, changing the line in fstab worked like a charm. Thanks!  

(Maybe this is some sort of a bug? )
