Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.
-
No low-effort posts. This is subjective and will largely be determined by the community member reports.

ZFS seems pretty RAM hungry and I don’t believe you can add new drives to an existing volume.
This is a common misunderstanding.
Short version; ZFS isn't RAM hungry, it's RAM aware. If your system has unused memory lying around, ZFS will use it to improve read performance. But it will give up that memory the moment anything else needs it.
No longer true
Oh hell yeah, I didn't know about the raidz extension. That's amazing!
It's in the latest TrueNAS versions. https://www.truenas.com/blog/electric-eel-openzfs-23/
It does take time to free ram. If you need the ram for other things it is best practice to limit the arc cache
Only when you have to write out to swap. In the case of something like ZFS, it stores data in RAM, looks for it there, then looks on the disk. So freeing up the RAM is effectively instantaneous; you just mark the space as free, then the other process writes into it.
Does TruNAS support this feature?
Related, will TruNAS work on a mini PC with an attached DAS?
How is the DAS connected?
Don’t own one yet. But I guess USB?
Don't use USB to connect hdds to a nas, it isn't reliable enough and will causes problems, it's just a matter of time.
So no mini PC then? I'd have to build a tower I suppose.
TrueNAS doesn't support external connectors like USB
It's part of ZFS 2.3.0, so it just depends what version TrueNAS is shipping with.
