For some reason, my locally installed snmp daemons decided to renumber
the elements in the hrStorageTable, meaning all the attached disks were
being either misreported or just plain dropped from my graphs
(paulbeard.no-ip.org/mrtg/blue/index.html). Not that the new numbering
doesn't make sense but I didn't know this was going to happen.
How to discover and fix it? snmptable is my friend. As shown here, the
memory used by the kernel is listed first, followed by the disks. The
disks were numbered starting at 1 before . . . . .
