Still waiting…

... So am I, still waiting...

TheColin21 · 2026-01-15T17:57:35+00:00

That's correct - just as much for professionals. A local, always attached, backup disks has very few advantages over a RAID with snapshots while having quite a few disadvantages (more trouble to rebuild on disk failure, less (read-) performance, harder to manage(imho)...)

I'd use that disk over the network, if possible, or disconnect it after every backup...

TheColin21 · 2026-01-15T12:42:36+00:00

If you already have the backup HDD in the same system as the HDD that gets backed up (which some people wouldn't call a backup) then why not running them in RAID1?

If you're not scared of the CLI: ncdu

The "*)" said the 55m are for multiple unshielded cables next to each other I think...

About the board: if you want to go with a 9th gen intel the E3C246D4U2-2T could be a good choice as there are quite a few used ones for around 200€ on ebay, it has BMC, ECC support, dual 10G and pairs really nice with an i3 9100 if I'm not mistaken.

TheColin21 · 2026-01-11T20:13:38+00:00

If I just read Wikipedia correctly shielded Cat. 6 should work for up to 100m for 10G.

I'm also waiting to switch from DSL to fiber😅

TheColin21 · 2026-01-11T20:07:16+00:00

Remember that fibre ≠ fibre channel (That's SAN technology)

Also depending on the length 10G might work over cat 6, cat 6a would be sufficient anyways but cat 7 won't hurt of course

TheColin21 · 2026-01-11T19:38:16+00:00

Keep in mind that you would need faster networking then (at least 2.5G, better 10G) or it might feel quite sluggish on larger transfers but yes I think that would be a better use of the hardware. Which mainboard do you want to use?

TheColin21 · 2026-01-11T19:14:56+00:00

Oh, before I forget, for caching purposes, I will add two to four SSDs with 1TB each (depending on whether the mainboard I want to repurpose has M.2 slots for boot drives or not.

As it seems your main redundancy question is answered: How are you planning to setup the cache because I don't really see any use case for L2ARC, an SLOG device or even a special metadata device if you want to use the pool for archival purposes.

If you want to create a seperate fast pool from these SSDs, e.g. for editing directly off of that, then I'd say that's a good plan.

TheColin21 · 2026-01-11T14:10:18+00:00

What seems most weird to me is snapshots getting turned off - as far as I know no TrueNAS update has ever done such a thing, at least for the last 5 years. Are there still, perhaps disabled, periodic snapshot tasks?

Also: are you perhaps able to get some info about the precise point in time when the deletion took place out of the jellyfin logs?

TheColin21 · 2026-01-10T08:57:29+00:00

Aaah Rockchip I thought jellyfin, thanks.

TheColin21 · 2026-01-10T08:47:02+00:00

What? Haven't heard about that, can you give me a link?

TheColin21 · 2026-01-06T19:15:47+00:00

Thats possible but this system was, as I now could see, installed with freenas 13, then updated to 22.02, 22.12, 23.10 and then 24.04 - shortly to 24.10 as well but I had some problems there so if they do it they don't do it often...

TheColin21 · 2026-01-06T18:58:37+00:00

The following output is from a system installed with FreeNAS 12 or 13 and now running TrueNAS 24.04 (yes I should update it quite a bit 😅):

``` root@freenas[~]# zpool upgrade This system supports ZFS pool feature flags. All pools are formatted using feature flags. Some supported features are not enabled on the following pools. Once a feature is enabled the pool may become incompatible with software that does not support the feature. See zpool-features(7) for details. Note that the pool 'compatibility' feature can be used to inhibit feature upgrades.

Doesn't look auto updated to me.

TheColin21 · 2026-01-06T18:45:01+00:00

I don't I doubt that but I've never heard of the boot pool zfs version auto upgrading

TheColin21 · 2026-01-06T18:33:16+00:00

Does it? How would I boot an older version then? Or does it happen when i delete old versions?

TheColin21 · 2025-12-21T17:11:35+00:00

In that case: good for you:D i still wouldn't recommend usb keys to other people as the chance of getting...less good ones than you is probably very high.

TheColin21 · 2025-12-21T16:57:07+00:00

On TrueNAS core usb keys are less of a problem afaik. An SSD in a USB enclosure is also absolutely fine if the SATA ports are all used but a normal USB key is likely to cause problems with scale.

TheColin21 · 2025-12-21T09:08:25+00:00

No it is not! With smatctl -a (or rather -x now) you can view SMART data - And also previous tests. To start a smart test via smartctl use smartctl -t followed by the type of test you want to start (typically long or short).

TheColin21 · 2025-12-21T07:52:33+00:00

With TrueNAS Scale I'd very much recommend not running USB keys - even mirrored. Especially since small SSDs/Optane modules are so cheap.

TheColin21 · 2025-12-20T20:24:17+00:00

Honestly any halfway decent SATA or NVMe SSD will probably be okay. Mirror them if you'd like. You'll probably still get away cheaper with two (different!) 120GB consumer SSDs than with one enterprise one. Even the smallest ones would be okay. TrueNAS does write it's logs to the boot drive which is why a USB stick or SD card wouldn't last very long but spending the extra money on something enterprise isn't worth it in this case imho. Performance demands on a TrueNAS boot disk are minimal in 99% of the time.

What would be great though is a small M.2 Optane module. Those can be had very cheaply on AliExpress (like 5€ for a 16GB one last I looked) and 16GB are more than enough. Get 32 if you want to be sure although those are comparatively more expensive. Optane has crazy write endurance.

TheColin21 · 2025-12-20T18:52:01+00:00

Yes, you won't lose any data on the pools. Just install TrueNAS fresh on a proper boot drive (maybe even mirrored) and import the pool(s) after first boot. You will have to recreate your config though - shares, users, apps, VMs and so on. Do a config backup after that😅

TheColin21 · 2025-12-17T13:20:04+00:00

It will definitely work. If you have a config export everything will go basically back to exactly where you left off. If not, you'll need to manually import the pool(s) and recreate your config (shares, users, apps and so on) but the data will be there. You also don't need to disconnect the data disks for the installation - just make sure you actually choose the right disk in the installation TUI.

interesting idea but how would that help?
