[PVE-User] Proxmox VE 8.1 released!

[Jan Vlach]

Hello Martin,

I'm sorry for stupid question, but I don't quite follow what the OpenZFS  2.2.0 with "the most important bugfixes from 2.2.1" means.

there is issue 15526 (https://github.com/openzfs/zfs/issues/15526 <https://github.com/openzfs/zfs/issues/15526>) in openzfs that enables block cloning feature by default and that on linux "eats" data.

OpenZFS 2.2.1 specifically switches the block cloning on by default to off by default and nothing else. ( https://github.com/openzfs/zfs/commit/479dca51c66a731e637bd2d4f9bba01a05f9ac9f <https://github.com/openzfs/zfs/commit/479dca51c66a731e637bd2d4f9bba01a05f9ac9f>  )

So is the code at 2.2.0 (toxic) eating data by default or at 2.2.1 where block cloning is disabled by default and therefore safe?

Thank you for clarification,
JV

As soon as you run Proxmox VE 8.1, you can upgrade Ceph to Reef. There are a lot of improvements and changes, so please follow exactly the upgrade documentation:
