 ## Overview
 
+**Gitea links**: Use `git.familie-schoen.com` (not IP) in chat. See `references/gitea-api-and-skills-versioning-2026-07.md`.
 This umbrella skill consolidates all Proxmox VE administration tasks:
 - **API/Auth** — SSH key `~/.ssh/id_ed25519_proxmox`, no BatchMode. RBD LXC: see `references/lxc-creation-rbd-clone-2026-07.md`
 - **Avahi Reflector** — CT 127 dual-VLAN, unidirectional. See `references/avahi-reflector-setup.md`
 - **LXC GPU** — privileged CT, device pass-through, ROCm/CUDA/Intel Arc drivers
-- **PVE-Native Volume Ops** — `pct move-volume`, `pct create --storage`, `pvesm alloc` + `mke2fs`, unprivileged CT permission mapping, Samba TimeMachine CT setup. See `references/pve-native-volume-ops-2026-07.md`
-- **Avahi mDNS Reflector** — cross-VLAN Bonjour/TimeMachine discovery via dual-interface CT. See `references/avahi-reflector-setup.md`
-- **Storage** — iSCSI/ZFS/RBD, Ceph pool redundancy, EC clone caveats, PG management, pool-full recovery, EC reweight trap, backfillfull flag, recovery tuning. See `references/lxc-creation-rbd-clone-2026-07.md`, `references/ceph-pg-management-2026-07.md`, and `references/ceph-recovery-ec-reweight-2026-07.md`
+- **PVE-Native Volume Ops** — iSCSI/ZFS/RBD, Ceph PG management, pool-full recovery, EC reweight trap, recovery tuning, OSD hot-plug, EC mixed-size optimization. See `references/ceph-osd-create-hotplug-2026-07.md`, `references/ceph-pg-management-2026-07.md`, `references/ceph-recovery-ec-reweight-2026-07.md`, `references/ceph-ec-mixed-size-optimization-2026-07.md`
 - **VLAN Bridge Setup** — correct interface creation order (VLAN first, bridge second), CT networking
 - **Infrastructure Monitoring** — Prometheus + Grafana + Alertmanager + Hermes webhook (auto RCA to Telegram). PVE exporter tuning, dashboard datasource fixes, alerting rules, Ceph/Galera/Blackbox coverage. See `references/alertmanager-webhook-setup.md` and `templates/alerting_rules.yml`.
