Bug 273369

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:
