Hello, I am not sure if this is the appropriate place to post this, looks like proper section to me.
I am currently using Ubuntu 12.04 precise x64 version. I have two hard drive on my machine, one is for windows (in ntfs system) and the other is for linux (ext4). When I freshly installed 12.04 few months ago, I put around 15GB swap space (2x the size of the RAM).

I usually get an warning at the boot screen saying that /dev/mapper/cryptswap1 is not yet ready or present. Haven't dig through it before, but today, after searching the forum related to this, but then I've found mine is not quite similar case.

So, I ran a few test on the terminal and here are the outputs:
Code:
zobayer@precise:~$ sudo mount -l

proc on /proc type proc (rw,noexec,nosuid,nodev)

Also, this is in my fstab file:
Code:
zobayer@precise:~$ cat /etc/fstab
# /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).

/dev/mapper/cryptswap1 none swap sw 0 0
zobayer@precise:~$
It says swap was allocated during installation, so where has it gone now?

Then I use blkid to see the drives and swap is not loaded there
Code:
zobayer@precise:~$ sudo blkid
/dev/sda1: LABEL="Windows" UUID="387CB19B7CB1547A" TYPE="ntfs" 
/dev/sda5: LABEL="Media" UUID="F2A0E5F2A0E5BCEB" TYPE="ntfs" 
/dev/sda6: LABEL="Games" UUID="2EBCEBAFBCEB702F" TYPE="ntfs" 
/dev/sda7: LABEL="Work" UUID="62F4F8A0F4F8779D" TYPE="ntfs" 
/dev/sda8: LABEL="Music" UUID="E278FE1778FDEA65" TYPE="ntfs" 
/dev/sdb1: UUID="af89c49c-7fec-4730-8402-14de941d1d91" TYPE="ext4" 
/dev/sdb5: UUID="7991773d-c24b-444e-95ef-a763b5c3b665" TYPE="ext4" 
zobayer@precise:~$
Here sda is the drive used by windows system, and sdb is for linux. And swap is not there.

So I checked system monitor, it also shows only the / and /home which are 75GB each. It also says Swap is not available (below the memory usage charts).

Also Disk Utility program shows that 15 GB is of Unknown format, although it tells the type is Linux Swap 0x82.

It is not that the performance is degrading, still I think swap should be needed. How can I get rid of the boot screen warning about cryptswap1 not being loaded and also loading the swap partition, cause 15 GB is quite a lot amount to be left unnoticed.

Should I delete the partition and recreate it? also during re-creation, should I make it as bootable?

Thanks in advance.
