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.

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.

ZFS zRAID is pretty good for this I think. You hook up the drives from one "pool" to a new machine, and ZFS can detect them and see that they constitute a pool and import them.
I think it still stores some internal references to which drives are in the pool, but if you add the drives from the by-ID directory when making the pool it ought to be using stable IDs at least across Linux machines.
There's also always Git Annex for managing redundancy at the file level instead of inside the filesystem.
Thanks, reading up on ZFS now on Ars https://arstechnica.com/information-technology/2020/05/zfs-101-understanding-zfs-storage-and-performance/
Sounds like I could dedicate a server machine to run a zRAID 1,2 or 3 with ZFS drives running on Linux or TrueNAS? Or were you thinking something a bit different for a setup?
That could work fine, probably? Or you could use it on the same machine as other stuff.
