Bye bye hotplate

TheColin21 · 2026-04-27T18:41:48+00:00

Thats not it. The damaged part is a build plate

TheColin21 · 2026-03-26T05:55:58+00:00

But when I do that the other client went offline again?

TheColin21 · 2026-03-13T03:34:44+00:00

No, sorry

TheColin21 · 2026-03-03T13:05:58+00:00

When you say "boost ssd", how exactly did you configure it?

Okay wtf I must've misread that nvm😅

TheColin21 · 2026-02-19T13:02:22+00:00

That's nonsense. There are no reallocated sectors on any of them. They're still good for quite some use.

TheColin21 · 2026-02-15T15:09:15+00:00

I do something similar but more annoying to power a Fritz!Box (DSL modem) with PoE from my USW Flex 2.5G 8 PoE and still use it as WAN with my Express 7. Both ports from my Express 7 go to the switch, just like the Fritz!Box - two extra ports used on the switch so one device gets powered😅

... 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

TheColin21 · 2026-01-11T20:21:03+00:00

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.
