Expected: Raid arrays have appropriate icons in launcher/disk utility etc. Used to be there in Precise
Actual: Icons are missing. Raid array has generic drive icon.
Compare the first screenshot, taken before upgrading from Precise to Quantal, and the second, taken afterwards.
There is a RAID1 array, created using the disk utility, which shows up with an appropriate icon on the launcher and matching emblem in nautilus, as well as showing up properly in gnome-disk-utility itself.
In the second screenshot, the raid array now has a generic drive icon in the launcher, just a folder icon in nautilus, and gnome-disk-utility itself seems to have no understanding at all that it has a raid device on its hands, nor any options any more to create new ones.
It kind of looks like a deliberate decision was made to have no desktop support for raid any more, but I haven't found any discussion of this, so at worst, some kind of explanation?
I don't even really care if gnome-disk-utility can be used to *manage* raid arrays; what launched me on this quest was simply wanting to have the raid *icon* in the launcher for the mounted filesystem. It used to be there in precise; on upgrade, it vanishes.
Actually encountered on a proper machine which I upgraded from precise to raring with barely a pause in quantal on the way through. Repeated in simpler form in vmware to check whether the loss happened from precise->quantal or quantal->raring. Seems to be the former, hence reporting it here.
(Simply restoring the gdu_ icons for raid to a raring system doesn't make it, or nautilus, use them. I confess I don't really know how this works. Setting the mount point directory's icon in nautilus doesn't affect the launcher icon, which is the one I actually want fixed.)
