The solution is quite simple anyways; to permanently disable swap you must:

1. swapoff -a.
2. edit /etc/fstab and comment any swap entries if present (you might be able to skip this step 2, and step 3 without step 2 may work for you).
3. run: sudo systemctl mask "dev-sdXX. swap" (where XX is the swap partition.

No it is not safe. The reason is that when the system runs out of RAM and will be unable to swap any of it, it might freeze with no chance for recovery other than a hard reset. It's not just about being able to suspend or not.

How do I know if swap is disabled Linux?

Check swap usage size and utilization in Linux

1. Open a terminal application.
2. To see swap size in Linux, type the command: swapon -s .
3. You can also refer to the /proc/swaps file to see swap areas in use on Linux.
4. Type free -m to see both your ram and your swap space usage in Linux.

How do I clear swap memory in Linux?

To clear the swap memory on your system, you simply need to cycle off the swap. This moves all data from swap memory back into RAM. It also means that you need to be sure you have the RAM to support this operation. An easy way to do this is to run 'free -m' to see what is being used in swap and in RAM.

How do I disable swap for Kubernetes?

Run the following command to update fstab so that swap remains disabled after a reboot. The aforementioned command comments out all swap entries in the /etc/fstab file. Note: Automated deployment of Platform9 Managed Kubernetes to Amazon Web Services does not have swap enabled on nodes, by default.

Should I disable swap Linux?

So, one might ask, since I have more than enough memory available, wouldn't it better to delete swap space? The short answer is, No. There are performance benefits when swap space is enabled, even when you have more than enough ram. Update, also see Part 2: Linux Performance: Almost Always Add Swap (ZRAM).

Why did Kubernetes disable swap?

The Kubernetes scheduler determines the best available node on which to deploy newly created pods. If memory swapping is allowed to occur on a host system, this can lead to performance and stability issues within Kubernetes. For this reason, Kubernetes requires that you disable swap in the host system.

Where is the swap file in Linux?

The swap file is a special file in the filesystem that resides amongst your system and data files. Each line lists a separate swap space being used by the system. Here, the 'Type' field indicates that this swap space is a partition rather than a file, and from 'Filename' we see that it is on the disk sda5.

Is using swap memory bad?

Answer: A: Swap memory is not detrimental. It may mean a bit slower performance with Safari. As long as the memory graph stays in the green there's nothing to worry about.

Does 16gb RAM need swap space?

If you have a large amount of RAM — 16 GB or so — and you don't need hibernate but do need disk space, you could probably get away with a small 2 GB swap partition. Again, it really depends on how much memory your computer will actually use. But it's a good idea to have some swap space just in case.

Should you disable pagefile?

If programs start to use up all your available memory, they'll start crashing instead of being swapped out of the RAM into your page file. ... In summary, there's no good reason to disable the page file — you'll get some hard drive space back, but the potential system instability won't be worth it.
