I just started my Proxmox journey so forgive me for asking stupid questions. I created a cluster from scratch with 3 nodes and played around with the ESXi migration wizard. I have maybe 8 VMs running, doing not at lot at the moment. Two PVE nodes have 4 TB RAM, 1 node has 2 TB RAM. On the nodes with 4 TB, I noticed 50% RAM usage, which surprised me, because it doesn't run (almost) anything. On the node with 2 TB, no shared memory is assigned. Upon investigating where this 50% consumption is coming from, I saw 2 TB is used as 'Shared'. Is this normal behavior?
See htop output, there's no VM nothing running on this 4 TB node:
