The subject says it all. I just created a 3 drive RAID5 array using software raid and mdadm. Everything is working fine, and hobbit even displays the raid disk space stats, but doesn't seem to graph it.
As far as I can tell, Hobbit does track your /mnt/raid5 disk in the graph.
hobbit also graphs a drive mount that is no longer there.
If you have filesystems that no longer exist, then the graphs on the "disk" status can get mixed up for a while. Basically, the "disk" status counts the number of lines of filesystems reported, so when your disk status contains
Filesystem 1024-blocks Used Available Capacity Mounted on /dev/sda3 72873600 12139768 57032056 18% / /dev/md/0 480726864 52734128 403573148 12% /mnt/raid5
then Hobbit assumes there should be two disk graphs, and it will pick the first two disk*.rrd files and graph those. If one of those two happen to be the filesystem that no longer exists, it will show up on the graph, and you'll be missing the other filesystem that should be there.
After some time - 24 hours, I believe - the graph on the "disk" status display will ignore the non-existing filesystem because the RRD file is no longer being updated, and the disk graph will show up with the correct display. This seems to be what is happening now.
