I can confirm this bug still exists on Ubuntu Jaunty, 9.04. Here are some filtered results from "mount":

~$: mount
/dev/sdc6 on /home type ext3 (rw,relatime,errors=remount-ro,acl)
/dev/mapper/isw_dihagdeiig_RAID03 on / type ext3 (rw,relatime,errors=remount-ro)
/dev/mapper/isw_dihagdeiig_RAID07 on /mnt/storage type ext3 (rw,relatime,errors=remount-ro,acl)
/dev/mapper/isw_dihagdeiig_RAID01 on /mnt/windows_vista type fuseblk (rw,nosuid,nodev,allow_other,default_permission,blksize=4096)

Basically the gnome-system-monitor applet can monitor hard disk activity. It monitors /dev/hd#, /dev/sd# (IDE & SATA drives, USB Sticks, etc.) just fine. However, devices which exist in /dev/mapper (from the dmraid configuration) are not monitored for disk I/O activity, and they should be.

In my particular example, the only disk which shows disk I/O in the applet is activity against my /home drive. The root filesystem resides on /dev/mapper/isw_dihagdeiig_RAID03, and it never shows I/O.

If you require any additional information, I'd be more than pleased to provide.
