I just recognized our proxmox system isn't using the full ammount of RAM anymore...
Unfortunately i can't tell since when this problem is persistent (how often do you check if you have "lost" RAM?...), i just recognized our Windows machine (MSSQL server) being utterly slow and having really poor RAM performance, while checking for the reason (was mainly a stuck process) i also recognized the missing RAM...
The Machine has 32GB RAM (4x8GB):
root@proxmox:~# lshw -c memory
But it's only seeing/using 24GB of it:
root@proxmox:~# cat /proc/meminfo
Any ideas?
BIOS hasn't been touched since setup 10 months ago, also the RAM size hasn't changed since (upgrade was planned for the next 2 months).
I haven't seen such behaviour yet, so i have no idea where to start... Thanks for any help!
