Reason: GPU multi-tenancy (frigate + ytdlp-highlights + llama-swap + immich-ml) was hitting 94% memory-request saturation on the old size. The benchmark on 2026-05-10 surfaced this when llama-swap stayed Pending despite GPU time-slicing being on (nvidia.com/gpu replicas=100) - the actual constraint was node1 RAM, not GPU. Procedure: drained node1, qm shutdown 201, qm set 201 --memory 49152, qm start 201, kubelet picked up new capacity (47 GiB / 45.5 GiB allocatable), uncordon, restored llama-swap + immich-ml. Out-of-band qm set is the path here (not Terraform) because VMID 201 is intentionally not managed by TF yet - the telmate/proxmox provider trips on iSCSI-disked VMs (see infra/stacks/infra/main.tf line 442). Adopt this VM into TF once we migrate to bpg/proxmox. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> |
