Hi all,

Does anyone know an easy way on how to free up my swap? I can see that there’s enough RAM available:

# free -m
              total        used        free      shared  buff/cache   available
Mem:            983         316          88           9         578         470
Swap:          1023         266         757

I would usually use the following command:

swapoff -a && swapon -a &

The & sign at the end would start the process in the background, then I would run the following to watch how the data is being copied from the SWAP to RAM:

watch free -m

It is important to have enough RAM available before running this.

Hope that this helps!
