Hello everyone,
I recently stumbled accross a strange behaviour of my PVE:
My storage uses ZFS as a filesystem and due to that my RAM is mostly full (total 128 GB).
All my allocated RAM for VMs is < 60 GB.

Strange fact: Instead of freeing RAM space by ZFS my VMs starts to swapping.

Swappiness is currently set to 2.


I mitigated this behaviour by disabling swap and commenting out the corresponding entry at /etc/fstab


Anyone else having this issue?
