Windows guests running stable VirtIO drivers incorrectly identify disc images as being thinly provisioned. This results in automated weekly defrag operations not consolidating days and instead attempting to pass through discards.
Performance of SQL VMs on single Proxmox nodes (no Ceph) has subsequently degraded over the last couple of months until we login and run "defrag c: /d" manually.
Does anyone know how to tell Windows that a disc is not backed by flash storage?
Running LVM2 (not thin) by striping data over software RAID1 members.
