Hi,
we upgraded our PVE cluster (very old HP G7 and 3yr old Dell R940) 6.2 to 6.4 and disk utilization in VMs raised from floor.
This problem is same for VMs on:
- nfs ssd storage (raw files), default (no cache)
- local ssd disks (LVM thick), default (no cache)
The change depends on VM type (higher on DBs, lower on system disks etc).
There is no utilization change from hardware view for both disk backends (even PVE system disks no change) so it's change only in VMs.
