swap file?

[apfaffman]

hi, everyone. i have a vm.swappiness question.

i've got a host with 96GB RAM and 16GB usb flash as proxmox os storage. an nfs share provides vm disk, backup and iso storage.

18 non-balloon guests utilizing about half of available RAM.

swap partition is 1.7 GB in size, fully maxed out. it's not immediately clear to me that this is a problem, but i thought i'd ask. i've considered disabling swap entirely, given how much RAM there is available on the system. would anyone tell me if i'm driving off a cliff or not?

Elimination swap completely is recommended (1.7 GB does not count compared with 96GB RAM, but may slow down the system when start swapping unexpectedly). Whenever possible I define "no swap" already during installation.
