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:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. 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.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

  7. No low-effort posts. This is subjective and will largely be determined by the community member reports.

I have two DELL T110 servers: master server has a 4TB WD Gold pool, the other slave server has a 2.5TB of mixed WD red drives pool. Slave is switched on once a week to get some automated plication tasks over from master. Only critical dataset are replicated e.g. immich with 20 years of photos. Both servers run Truenas Scale ElectricEel-24.10.2.4. Its occurred to me that ElectricEel-24.10.2.4 does not use the ix-applications folder anymore to store installed docker images. That means that although I'm replicating the Immich dataset, I'm not replicating the docker images so if master server fails, I can't just turn on slave server. Is it possible to replicate the old ix-applications folder which btw is where?

OK, so maybe I didn't explain myself. What I meant was that I would like resilience so that if one server goes down, I've got the other to quickly fireup. Only problem is that slave sever has a smaller pool, so I can't replicate the whole pool of master server.
