+ZFS comes with an event daemon `ZED`, which monitors events generated by the ZFS
+kernel module. The daemon can also send emails on ZFS events like pool errors.
+Newer ZFS packages ship the daemon in a separate `zfs-zed` package, which should
+already be installed by default in {pve}.
-To activate the daemon it is necessary to edit `/etc/zfs/zed.d/zed.rc` with your
-favorite editor, and uncomment the `ZED_EMAIL_ADDR` setting:
+You can configure the daemon via the file `/etc/zfs/zed.d/zed.rc` with your
+favorite editor. The required setting for email notification is
+`ZED_EMAIL_ADDR`, which is set to `root` by default.
--------
ZED_EMAIL_ADDR="root"
Please note {pve} forwards mails to `root` to the email address
configured for the root user.
-IMPORTANT: The only setting that is required is `ZED_EMAIL_ADDR`. All
-other settings are optional.
