# NAS 

* clean install newest FreeBSD 14.2
	* move OS /home into /data/home zpool/home
	* mount ISO over IPMI
* Manage old zpool:
	* (old OS) zpool export zpool
	* (new OS) zpool import -N zpool
	* zpool status
	* zpool upgrade
	* zpool upgrade zpool
	* https://docs.freebsd.org/en/books/handbook/zfs/#zfs-zpool-upgrade
* Syncthing shares on separated ZFS subvolumes
	* zfs autosnapshot retetion policies
* pyrotechnics & private data zfs copies=2?
* Applications in VMs
	* Photoprism
	* Homeassistant? or in jail?
* Applications in seperate freebsd jails
	* Syncthing
	* Transmission
	* (existing -> upgrade) Gitea
	* Template FreeBSD 14.2
	* Samba
	* VTVBB sync + go tooling
	* Cache: pkg + freebsd update (for jails)
* Data partitioning
	* zroot (ssd OS only)
	* zpool (14TB hdd mirror)
		* /data/home

Host OS services:
 * SSH + sshguard

Improvements & things to not forget:
* backup settings from /etc and /usr/local/etc before SSD OS disk wipe
* private keychains daily snapshots (separate Syncthing share + copies=2?)
* Syncthing
	* per-share zfs subvolume
	* per-share needs .zfs ignore or else snapshots are propagated
* crontab(s) backup
* samba config
* gitea backup
* sshguard
* jails settings backup
* vanilla jails management with templates
* Migrate from zfstools auto-snapshot and prune to Python zfs-autobackup?
	* See blog https://it-notes.dragas.net/2024/08/21/automating-zfs-snapshots-for-peace-of-mind/
* URLs for (web)services with nanodash for homelab + quick access
* Upgrade gitea and migrate sqlite to postgres

* Migrate all automations Hue -> Home Assistant
* Samba network share
	* AVAHI/Bonjour autodiscovery
* Automount network shares on macOS
* ZFS zpool scrub monthly cron
* Homeassistant in FreeBSD jail rc.d service file for auto-start on boot

# Syncthing share enrol on ZFS subvolume

1. Create zfs subvolume: `zfs create ...`
2. Set zfs-auto-snapshot property (for zfstools) : `zfs set ..`
3. Create share in Syncthing web GUI
4. Ignore .zfs folder (to not propagate to connected peers): filter `.zfs`

# ZFS dataset datablock copies

For extra redundancy amount of datablock copies can be set and tested:

```
# zfs create data/test-dataset/dataset-1
# zfs list
# zfs set copies=2 data/test-dataset/dataset-1
# zfs get copies data/test-dataset/dataset-1
root@mango:/data/test-dataset/dataset-1 # dd if=/dev/random of=testfile bs=64K count=1024
1024+0 records in
1024+0 records out
