[SOLVED] Swap up to 93% of usage

[Globul]

Hi,

I regularly have the swap at over 93%
However, I have set the sappiness to 15 and the memory of the system is under 70%

It's probably not a problem. How much memory does you system have? How big is your swap space? Are you experiencing actual issues?

The Linux kernel probably though the memory was better used for I/O and moved data that was not used much to swap. Only when the system is reading from swap a lot (thrashing), it indicates that you need more memory.

When the swap is high, some VM are slower i think...

ok, so I assume that this is a normal working?

You can disable swap or set vm.swappiness to 0 (so it will only swap when out of memory), if you think that is better for your VMs.

Your Proxmox is out of support for some time. You should upgrade to Proxmox VE 7.4.

I know... I have to upgrade.
I'm a little afraid that it will go wrong, for now I'm waiting.

Thanks for your answers...
