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.

Unless you are missed the news. Bug found in OpenZFS causing data corruption, FreeBSD, Linux and illumos are all affected.

Good description of the bug

Some good news from bug tracker on OpenZFS

OpenZFS 2.2.2 and 2.1.14 released with fix in place. If you don't get your OpenZFS direct from here, point your vendor at it.

Patch your systems!!

TrueNAS iX Systems statement with interim mitigation steps.

The statement is very informative. The bug happens under increased read/write operations to the same file causing a race condition.

I also found interesting:

Despite the bug being present in OpenZFS for many years, this issue has not been found to impact any TrueNAS systems. The bug fix is scheduled to be included in OpenZFS 2.2.2 within the next week
