 If you don't have that set then this may be then due to an update of EdgeOS or a new device type, please [create an issue](https://github.com/librenms/librenms/issues/new).
 
+#### <a name="faq26"> Why are some of my disks not showing?</a>
+
+If you are monitoring a linux server then net-snmp doesn't always expose all disks via hrStorage (HOST-RESOURCES-MIB). We have additional support which will retrieve disks via dskTable (UCD-SNMP-MIB). 
+To expose these disks you need to add additional config to your snmpd.conf file. For example, to expose `/dev/sda1` which may be mounted as `/storage` you can specify:
+
+`disk /dev/sda1`
+
+Or
+
+`disk /storage`
+
+Restart snmpd and LibreNMS should populate the additional disk after a fresh discovery.

 The easiest way to show you how to do that is to link to an existing pull request that has been merged in on [GitHub](https://github.com/librenms/librenms/pull/352/files)
