GNOME Bugzilla – Bug 667517
device-mapper devices shown with the wrong dev name
Last modified: 2012-11-15 17:47:54 UTC
device-mapper devices are listed as having a dev name of /dev/dm-0, etc, rather than their canonical name, /dev/mapper/foo. This affects both LVM and dmraid.
As of gnome-disk-utility 3.4 everything was rewritten to use udisks2 and GDBus. FWIW, in the current version, we're using "nicer" names for device-mapper devices. This problem has been fixed in our software repository. The fix will go into the next software release. Thank you for your bug report.
