Configure Debian to use lost SWAP Partition

hi

During the second OS (CentOS) setup, the shared SWAP partition was formated and now I get the following under Debian:

Code:

# free
             total       used       free     shared    buffers     cached
Mem:        507524     251436     256088          0      11488      78332
-/+ buffers/cache:     161616     345908
Swap:            0          0          0

Howto configure Squeeze to use again this SWAP partition?

I hope someone corrects me if I'm wrong here, but I believe you're looking for the swapon (and mkswap, if needed) commands.
Make sure your /etc/fstab looks alright, in respect to your swap partition. If you have the partition identified by UUID, confirm that the UUID is still what it's supposed to be (blkid).

You probably have to modify the UUID in the line for your swap partition on your /etc/fstab file. To know the UUID, type:

Code:

ls -l /dev/disk/by-uuid

and see which UUID points to your swap partition (then change the old UUID for the new one, on your /etc/fstab file, reboot and your done).

Thx a lot, I've done and now it works well.

BTW blkid command shows UUID as well.

Yeah, blkid returns the UUID of all the partitions in the system (I "discovered" it recently for another post here in the forum)
