Bug#597994: gnome-panel: "system monitor" does not show disk I/O when using LVM?

[Miles Bader]

Package: gnome-panel
Version: 2.30.2-2
Severity: normal



I use the gnome-panel "system monitor" widget, showing bar charts of
CPU/disk/network/etc activity.

Generally all of these seem to work -- but on my home computer, the
"disk I/O" chart always shows zero activity, even when there's
clearly lots of disk I/O going on.  However, on my work computer, the
disk-I/O chart seems to work correctly.

The only obvious difference between these two systems that may be
relevant is that my home system has most of its filesystems in LVM
(so the "df" command shows "/dev/mapper/..." for the disk devices).

I'm wondering if the gnome-panel system-monitor has a bug where it
fails to work with LVM...

Thanks,

-Miles
