To a certain degree, yeah. > I am asking because I had problems with hal detecting > my dm-raid devices. See here: > > http://lists.freedesktop.org/archives/hal/2009-June/013403.html Currently DeviceKit-disks will properly detect the devices and things will look just fine in Nautilus / GTK+ file chooser or anything else using GVfs, see https://bugzilla.redhat.com/show_bug.cgi?id=495152 for the bug where this (and other things) was fixed. Still, things will look pretty non-sensical in Palimpsest, e.g. this screenshot https://bugzilla.redhat.com/attachment.cgi?id=339015 but that's pretty much just because fakeraid currently is implemented in a way that completely screws over the rest of the system - e.g. using device-mapper in "interesting ways" and conveniently removing real partitions for physical disks. Now, ideally things would look like what we do for md-raid http://people.freedesktop.org/~david/gdu-raid5.png and maybe with the switch from dm-raid -> md-raid this can be done. I don't know. Anyway, to support the whole range of multi-disk solutions on Linux we'd need to support - md-raid (95% done, only the "create RAID array is missing, see http://people.freedesktop.org/~david/gdu-create-raid-1.png and http://people.freedesktop.org/~david/gdu-create-raid-2.png for some work in progress) - LVM2 (not done, am planning to work on it soon) - btrfs (not done, am planning to work on it soon) - dm-raid (not done, no plans to work on it yet) - multipath (not done, no plans to work on it yet) but of course this list is not complete as device-mapper conveniently lets you configure your system in very interesting ways that completely doesn't map to any sane UI (LVM2 is the exception). (Personally I never understood why one would want to use fakeraid on Linux - it's not like it is any faster than using native software raid and it locks you into on-disk formats and makes it harder to manipulate the arrays outside the BIOS. I bet it probably has something to do with people dual-booting Windows. I don't know) Anyway, hope this helps.
