[solved] Swap not activating

I've tried hibernating but I have found that there is no swap.
I have swap partitions on my system and it is apparently in my fstab:

# 
# /etc/fstab: static file system information
#
# <file system>        <dir>         <type>    <options>          <dump> <pass>
none                   /dev/pts      devpts    defaults            0      0
none                   /dev/shm      tmpfs     defaults            0      0


/dev/dvd /media/dvd   auto    ro,user,noauto,unhide   0      0
/dev/sr0 /media/cdrom auto rm,user,auto 0 0 #The new entry.
UUID=41f53992-ef11-49eb-91e8-a5a3bf6b66c0 / ext3 defaults 0 1
UUID=50a545bc-5348-4c23-a8d9-933640b62a5a swap swap defaults 0 0

I have searched on these forums and have found that the common problem is duplicate entries in fstab, but that is the not true for my case.

I've tried swapon and mkswap but they appear to have no effect!

Re: [solved] Swap not activating

If you've run mkswap, you probably changed the UUID of the partition. You may also want to check into the possibility that your hibernation/suspend scripts are running mkswap behind the scenes and changing the UUID on you.

You can get a listing of swap partitions that are enabled from /proc/swaps.

I agree with neotuli. There is a possibility that the UUID in your fstab is incorrect. There is a topic about changing your swap UUID to the correct one. You can find it here.

Aha! Thank you elmer_42 for that link. It did the trick!
I'm going to reboot and see if the swap mounts.

Re: [solved] Swap not activating

ok I rebooted and everything is fine.
How would I go about marking this thread as solved?

Generally you should edit your first post, and you can just change the title. But I've done it for you this time

@OutOfReach

You can edit the first post to change the thread title.

Too slow...
