Why Proxmox Shows Disk 100% Full When the VM Has Free Space (The Broken Discard Chain)

September 1, 2026August 29, 2026 by Daniel Hayes
Proxmox virtual storage architecture diagram of the six-link discard chain, from SATA/IDE TRIM dropped at the bus to VirtIO SCSI with discard=on, beside a 28 August 2026 benchmark reclaiming 228 GB and dropping pool utilisation from 84.2% to 48.6%.

Why thin-provisioned Proxmox storage stays 100% full when VMs show free space: the broken 6-link discard chain, fstrim limits, and the VirtIO SCSI fix.

Broadcom VMware 2026 licensing core count matrix showing the 16-core socket floor penalty, with per-node owned-versus-paid core counts and the Proxmox migration breakeven.

Broadcom retired per-socket vSphere licensing for a 16-core minimum per CPU. Real cost buildup for 2-to-5 host SMB clusters and when staying is cheaper than migrating.

September 1, 2026August 29, 2026 by Daniel Hayes
Infrastructure post-mortem diagram of a VMware vSphere to Proxmox VE cutover, listing three audited failures — 0x7B INACCESSIBLE_BOOT_DEVICE, snapshot delta stall at 0% free, and dracut missing kernel ramdisk — beside the bcdedit and pnputil remediation sequence.

Five recurring causes of VMware-to-Proxmox migration failure — VirtIO controller, snapshots, dracut, thick provisioning, mounted ISOs — and the fix for each.
