 I've just built a new system for a client, using five new 1.5 TB Seagate
 drives for storage (with a separate boot drive), using Mythbuntu Karmic.

 If each storage drive is partitioned identically, MythTV assigns the
 identical partitions of all the drives to a single MythTV drive, instead
 of each to their own MythTV drive. It does not matter if the drives have a
 single partition or two partitions as long as the drives are partitioned
 identically.

 It does not matter if the identical partitions are in the same storage
 group or in their own individual storage groups, they are  concatenated to
 a single directory (as reported on the MythWeb status page, see attached
 screenshot snapshot1.png).

 Instead of having the entire 7.5 TB available, only 1.5 TB is made
 available, i.e. the size of only one drive, not all five installed and
 configured.

 This seems to be file system independent; I tried both xfs and ext4 (but a
 mixture of file systems wasn't tested as I've only just thought of it.)

 I worked around this problem by making the partition sizes slightly
 different on each drive, which yielded proper behaviour.
