zfs-zed.service errors in logs

[MightySlaytanic]

Hi,
I'm running a PBS LXC privileged container and I've noticed the attached errors in the logs.

root@ProxmoxBackupServer:~# proxmox-backup-manager versions                                                                                                                                                 
proxmox-backup-server 2.3.2-1 running version: 2.3.2

The service is running now but it seems to be continuously shutdown/restarted and sometimes gives errors,
since I'm not using ZFS can I simply disable the service via sysctl or is it triggered by something else?

Hello,

If you are not using ZFS in the PBS LXC, you can safely disable the service via systemd.

I had the same problem and I disabled the service in question with the following command:

systemctl disable zfs-zed.service

This stopped systemd from polluting the syslog.

I guess zfs-zed runs on PVE host anyway so it's safe to disable it in PBS container.
