Everything That Cost Us a Day Returned Success: Nine Versions of esx_ready.sh on a Live Fleet

Noah Farshad / October 23, 2026

One day, three fires, nine versions of esx_ready.sh on a live VCF 9.1.1 fleet, and nothing crashed: an upgrade that reported success and moved nothing, a cluster leave that released no disks, a depot staged onto the vSAN cache disk, a retried SDDC Manager task reading stale inventory. The build gate VCF 9.1.1 enforces, the chain of vSAN disk ownership, the feature that had to be deleted, and the stub harness that turned every failure into a test before its fix shipped.

The Certificates Expired a Year After a Date Nobody Was Watching: Five TKG Clusters Back From the Supervisor

Noah Farshad / October 23, 2026

Five VKS guest clusters on VCF 9.1.1, every API server down, every control plane certificate expired on the anniversary of a node rollout nobody remembered. Where TKG certificates actually live, why kubeadm’s renewal can hand you a certificate no client accepts, why the nodes have to be done in series when there is no quorum, and the script that took three production clusters from connection refused to READY in an afternoon.

Four imported clusters showed Prepared, Success and green hosts, and TEP IP Address: Not Set on every one. What a VCF import leaves behind, the five places an overlay breaks without an error, and a tool that copies the cluster that works.

Importing ESXi 8 Into VCF 9.1 When ESX 9 Won’t Run on the Hardware

Noah Farshad / October 16, 2026

ESX 9 won’t run on Broadwell and VCF 9.1.1 won’t commission ESXi 8, so the clusters are built on vSphere 8 and imported. The vCenter upgrade that removed an NSX collision, the fourteen steps a cluster has to pass before VCF will take it, and the rules the tooling lives by.

Noah Farshad / October 16, 2026

Avi 32.1.3 on VCF 9.1.1 with NSX Federation: controllers deployed through VCF Operations, a licence pool that was empty, a GM: prefix that stopped the first VIP, and KB 428430’s answer. One controller cluster per site, local objects only.

Bridging Blue to Green: Moving Live Workloads to a New NSX Federation, One Subnet at a Time

Noah Farshad / October 16, 2026

Production VMs moved from a two-site NSX 4.2 Federation to a new VCF 9.1 Federation and kept their addresses: a Layer 2 bridge per subnet, waves of vMotions, a per-subnet gateway flip, and a tested way back from every step. The tooling is public.
