The Technology pop-up menu is unclear which option it applies to, I'm guessing just mirroring and striping. A thin black line separating would make this more clear. Or drop the option entirely (honestly in a GUI I don't see the advantage of LVM or MD over btrfs integrated RAID, compared to the cluttering of the UI that results from providing the choice.) I have removed the "Technology" combobox for the time being. As of now, there is no way to create new container devices (lvm vg, btrfs vol, md) whose member/component devices are anything other than partitions. This functionality will get in at some point, but it will have to wait a bit. > > 5. Error detection (parity). Is this the metadata profile? If so, I think it being unchecked by default is confusing, because there isn't a -m none option. I'd even suggest the UI could be eliminated by making some reasonable choices for the user based on the first two options: > > Single disk, use metadata default of duplicated on that single disk. > Multiple disk where -d raid0 or raid1, use -m raid1 because it's safer. > Multiple disk where -d raid10, use -m raid10 We're not allowing explicit selection of metadata profile. We'll probably do something similar to what you have above. As of now, we're not passing any -m option to mkfs.btrfs. > > 6. Compression lacks an LZO option, and defaults to ZLIB. I've also removed the compression checkbutton since compression can be enabled post-install.
