           Summary: digikam does not get UUID for disk devices inside LVM
           Product: digikam
           Version: 1.9.0
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: kde at pupat-ghestem.net


Version:           1.9.0 (using KDE 4.6.2) 
OS:                Linux

When adding an album on devices inside a LVM, digikam complains that it is not
able to identify the storage medium of the path. The album is then identify
only by its path which poses other problems if the device is LUKS and one
starts digikam without unlocking the LUKS device (see #271591 for more
details).

Reproducible: Always

Steps to Reproduce:
Add an album on a device inside an LVM

Actual Results:  
digikam is unable to identify the storage medium of the path

Expected Results:  
digikam should be able to identify the storage medium of the path

I understand that digikam relies on solid-hardware to find out the storage
devices.

Below is the solid-hardware output for one of a LUKS disks stored in a LVM for
which digikam fails:

udi = '/org/freedesktop/UDisks/devices/dm_2d7'
  parent = '/org/freedesktop/UDisks/devices/dm_2d2'  (string)
  vendor = ''  (string)
  product = 'luks'  (string)
  description = 'luks'  (string)
  Block.major = 253  (0xfd)  (int)
  Block.minor = 7  (0x7)  (int)
  Block.device = '/dev/dm-7'  (string)
  StorageAccess.accessible = true  (bool)
  StorageAccess.filePath = '/home/luks'  (string)
  StorageAccess.ignored = true  (bool)
  StorageVolume.ignored = true  (bool)
  StorageVolume.usage = 'FileSystem'  (0x2)  (enum)
  StorageVolume.fsType = 'ext4'  (string)
  StorageVolume.label = 'luks'  (string)
  StorageVolume.uuid = '13ea945a-ef5b-4db7-9fc6-34e1bd00df96'  (string)
  StorageVolume.size = 450102292480  (0x68cc2ff000)  (qulonglong)


Below is the solid-hardware output for one of a non-encrypted disks stored in a
LVM for which digikam fails:

udi = '/org/freedesktop/UDisks/devices/dm_2d1'
  parent = '/org/freedesktop/UDisks'  (string)
  vendor = ''  (string)
  product = 'homes'  (string)
  description = 'homes'  (string)
  Block.major = 253  (0xfd)  (int)
  Block.minor = 1  (0x1)  (int)
  Block.device = '/dev/dm-1'  (string)
  StorageAccess.accessible = true  (bool)
  StorageAccess.filePath = '/home'  (string)
  StorageAccess.ignored = true  (bool)
  StorageVolume.ignored = true  (bool)
  StorageVolume.usage = 'FileSystem'  (0x2)  (enum)
  StorageVolume.fsType = 'ext4'  (string)
  StorageVolume.label = 'homes'  (string)
  StorageVolume.uuid = '92903620-f0f3-4f5a-bce2-7fb6de0650f7'  (string)
  StorageVolume.size = 93415538688  (0x15c0000000)  (qulonglong)
