Zfs-utils 2.3.1-1 breaks zfs-zed.service

General

EDIT:

It appears the latest CachyOS kernels are compiled with OpenZFS 2.3.0 and that’s probably why zfs-utils 2.3.1 is failing. I’m using linux-cachyos-zfs 6.13.6-2.

ORIGINAL:

After upgrading to zfs-utils 2.3.1-1 the zfs-zed.service fails to start. I ran diff on the the good/bad services and the /etc/default/zfs files they reference and they appear identical so I don’t know what the problem is. So for now I’m just using 2.3.0-1, I hope that’s not dangerous.

Here is the failed service status output:

After downgrading to zfs-utils 2.3.0-1 the service starts correctly. Here is the successful service status output:

zfs 2.3.1 was pushed along with 6.13.7. I’m not sure why the kernels aren’t pushed yet – maybe they’re still building. Sorry for the inconvenience.

Thanks for the response @naim. The new kernels need to be pushed ASAP because running the incorrect zfs-utils, at least the failed zfs-zed service, can endanger data integrity dependent upon what ZFS operations are performed.

Starting now compilation. Should be up int he next hrs.

Thanks @ptr1337. I installed kernel 6.13.7-1 and zfs-zed 2.3.1-1 on my workstation and server and everything is working perfectly. Marking bug as solved.

Nothing to be sorry about @ptr1337. You have a lot on your plate and you’re doing an awesome job! CachyOS is fantastic and I can’t thank you enough for creating it. :slight_smile:
