Alternatively, we may run theswapon commandto view the system swap space usage summary (we’ll not get any output). # swapon -s We can resolve this issue, bycreating a swap space in Linux. Note: The content of this file is cleared at system shutdown: new data is stored in it on ...
2. Create Swap Usually, the allocated space for swap is used as a separate partition. Before we create a swap file it is best to check the disk usage: df -h The output should be similar to this: Filesystem Size Used Avail Use% Mounted on ...
I'm using Linux containers on Docker for windows. Because of using gcc inside one of the containers I need to assign more than 4GB swap file to this container. Previously, I used swapon to add more swap files but this stopped working with error: swapon: failed operation not permitted All...
