# pfi-pve: PVE 8.4 → 9 upgrade, the package half (Prime go 2026-10-04). Does NOT reboot.
#   scripts/elway infra-ops@10.250.250.31 --playbook playbooks/pfi-pve-pve9-upgrade.yaml
# Prereq: playbooks/pfi-pve-pve9-prep.yaml, then the PVE 8 reboot test (it validates the new GRUB, NIC pins and kernel
# before trixie lands; see docs/runbooks/pfi-pve-pve9-upgrade-plan.md). Template: playbooks/esh-nas-pve-pve9-upgrade.yaml.
# The dist-upgrade runs DETACHED (systemd-run → /root/pve9-upgrade.log), so a dropped ssh cannot kill it mid-dpkg.
# Poll: sudo tail /root/pve9-upgrade.log ; systemctl status pve9-dist-upgrade
# Then: playbooks/pfi-pve-pve9-prereboot.yaml, then the reboot.
# Rollback: `lvconvert --merge pve/root-pre-pve9` and reboot (the merge runs at the next activation of pve/root);
# from a rescue boot if 9 does not boot. The snapshot covers / and /boot (one LV), not the ESP or guest storage.
