Yesterday I ran into a problem in a SWAP partition on an Astaro Command Center, so I decided to restart with an Ubuntu CD, and my first attempt to repair the system was with the fsck command, but when trying to use it I got the message fsck.swap: command not found
So I check with the badblocks command that the partition had no bad blocks.
sudo badblocks -v /dev/sda2 |
The above command did not return any error, then searching the Internet I found this simple way to rebuild a damaged swap partition.
sudo swapoff /dev/sda2 sudo mke2fs -c /dev/sda2 |
If the above commands do not report any problems and complete successfully, then continue with the following:
sudo mkswap /dev/sda2 sudo swapon /dev/sda2 |
Ready, reboot and test, although this process is run in Astaro, applies to any Linux with a similar problem.

easier, faster, simpler to delete the faulty partition, recreate, and then swapon?
gparted is your friend… but is it not on the Ubuntu CD?
I agree that the process of “check-delete-recreate” does not really fix the error as such. Neither it shows how to fix the disk error(s) if there are any.
