ZFS is a combined file system and logical volume manager designed by
Sun Microsystems. Starting with {pve} 3.4, the native Linux
ZFS comes with an event daemon, which monitors events generated by the
ZFS kernel module. The daemon can also send emails on ZFS events like
-pool errors.
+pool errors. Newer ZFS packages ships the daemon in a sparate package,
+and you can install it using `apt-get`:
+
+----
+# apt-get install zfs-zed
+----
To activate the daemon it is necessary to edit `/etc/zfs/zed.d/zed.rc` with your
favourite editor, and uncomment the `ZED_EMAIL_ADDR` setting:
+--------
ZED_EMAIL_ADDR="root"
+--------
Please note {pve} forwards mails to `root` to the email address
configured for the root user.
To make the swappiness persistent, open `/etc/sysctl.conf` with
an editor of your choice and add the following line:
- vm.swappiness = 10

+vm.swappiness = 10
