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