Fixing the Swap Partition

Overview

In versions 3.3.0 - 3.4.3 of SFTP Gateway, the swap partition exists upon creation of your VM. However, after stopping or restarting the VM, the swap partition will be missing.

This is due to /var/lib/cloud/scripts/per-boot/create_swapfile.sh missing the line #!/bin/sh at the top of the file.

Loss of swap partition can be an issue if your memory is being highly uitilized, although it isn't a major issue.

This issue will be resolved in version 3.4.4 of SFTP Gateway.

Solution

To manually fix the issue, SSH into your VM on port 2222 & elevate your privileges:

sudo su

Change directories & edit the swapfile:

cd /var/lib/cloud/scripts/per-boot/
nano create_swapfile.sh

Add this line at the top of the swapfile:

#!/bin/sh

Save the changes to the swapfile, then restart the instance so it will have the swap partition on boot.
