mrcharles 019ab468bf feat: relocate D3 SSD from tsys4 USB to tsys5 SAS on Friday
Deep-dive on tsys4/5 storage controllers revealed:
- tsys4: 4-port SATA, all occupied; D3 SSD is USB 2.0
- tsys5: LSI SAS1068E (8-port, 5 free) + ICH10 SATA (2 free) + USB 3.0

Decision: move D3 (SK hynix SSD) to a tsys5 SAS port. Eliminates USB
bottleneck and consolidates all fast storage on tsys5: NVMe (local) +
D3 SSD + T5-SSD + 4 HDD exports.

Updated storage architecture, speed tiers, critical VM placement,
failure survival matrix, StorageClass design, and Friday plan.

mrcharles ea2048dc87 fix: correct storage bus types after deep-dive on tsys6/7
Verified via lsblk TRAN column and dmesg that tsys6/7 local-lvm is
backed by WD My Passport portable HDDs on USB 2.0 (~30 MB/s), not
internal SATA/SAS as previously assumed. Both R610 and R620 only have
EHCI controllers -- no USB 3.0/xHCI. tsys7 has 5 empty SATA ports but
no drives installed; tsys6's SAS controller is disabled in BIOS.

Corrected all wnode recommendations: tsys6/7 stay on NFS (faster than
their USB 2.0 local-lvm). Only tsys3/5/9/2 have local storage suitable
for VM boot disks.

Also discovered tsys3 boots from Samsung PM961 NVMe 512GB (previously
documented as HDD). Its 349 GB local-lvm is the fastest existing local
storage in the fleet.

Updated speed tier table, wnode placement tables, storage distribution
matrices, migration plan, and caching strategy across PROJECT.md and
K8S.md.

mrcharles db575080c9 docs: integrate tsys2 hardware findings from Windows inventory
tsys2 validated via PowerShell on Windows: 2 SSDs (Samsung 960 PRO
NVMe 512GB + Samsung 850 EVO SATA 1TB) -- the best local storage in
the fleet. wnode-tsys2 needs no NFS; boot on NVMe, bulk data on SATA
SSD. Both NICs are USB dongles (ASIX + Realtek) -- unavoidable on
this laptop form factor, no PCIe NIC expansion possible.

Updated storage tiers, wnode placement, and k8s labeling to reflect
that tsys2 is the fastest-storage worker node. Marked TODO.md items
as resolved.

mrcharles 11ae08f7e6 docs: add TODO.md with tsys2 Windows inventory commands
Adds the PowerShell and cmd.exe commands the user needs to run on the
Windows host (pfv-tsys2) to gather disk, network, RAM, GPU, and PCIe
details before rebuilding it as Proxmox. Also documents the Friday
maintenance window steps (tsys4 NIC+RAM, tsys5 cable+NVMe) and open
questions for the next session.

mrcharles a791baa085 chore: ignore python bytecode and document git workflow
Add __pycache__/*.pyc to .gitignore and remove the tracked bytecode
file. Add version control instructions to AGENTS.md for future sessions.

mrcharles 422999bf3c chore: initialize repo with full project state
Performance optimization engagement for a 7-host Proxmox R&D cluster.
Captures the accumulated work across host tuning, network analysis,
fleet assessment, and kubernetes architecture planning.

Contents:
- Host-side tunings (scripts/): CPU governor, swappiness, BBR, NFS
  nconnect, tuned profiles -- complete on 5 of 7 hosts
- Validation + benchmarking scripts: iperf matrix, bond/NFS fixes
- Collected host data (returned-logs/): check.sh output from all 7
  hosts + iperf results, including newly-validated pfv-tsys9
- AGENTS.md: operating context for AI agents
- PROJECT.md: board-ready fleet assessment with VM placement and
  storage redundancy analysis (40 VMs across 7 hosts)
- K8S.md: kubernetes architecture deep-dive covering cnode/wnode
  distribution, StorageClass design, and ETL/HPC workload planning
