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!!

For all Proxmox users it looks like the new ZFS kernel module with the patch is included in the opt-in kernel 6.5.11-6-pve for now.

The kernel 6.5 actually became the default in Proxmox 8.1, so a regular dist-upgrade should bring it in. Run "zpool --version" after rebooting and double check you get this:

zfs-2.2.0-pve4 zfs-kmod-2.2.0-pve4

As this versions are patched for bug.
