# PFV NFS tuning sysctl overrides
#
# Applied AFTER tuned via pfv-nfs-tuning.service (systemd oneshot).
# These override tuned's network-throughput/virtual-host 16MB TCP buffer
# caps with 128MB for high-BDP NFS over 1-4 GbE LACP links.
#
# Install on ALL Proxmox hosts:
#   cp 99-pfv-nfs.conf /etc/sysctl.d/99-pfv-nfs.conf
#   cp pfv-nfs-tuning.service /etc/systemd/system/pfv-nfs-tuning.service
#   systemctl daemon-reload && systemctl enable --now pfv-nfs-tuning.service
#
# Created: 2026-07-31
# Deployed: tsys1, tsys3, tsys4, tsys5, tsys6, tsys7, tsys9
