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.
