Description Manuel Amador (Rudd-O) 2011-03-24 11:41:15 UTC

Version:           unspecified
OS:                Linux

As per the debugging info here:

udi = '/org/freedesktop/UPower/devices/line_power_ADP0'
udi = '/org/freedesktop/UPower/devices/battery_BAT0'

the NFS volume is nowhere to be found.  This makes amarok think that the music is directly on the root volume.

In addition to that, the root file system is on a ZFS dataset, and, of course, solid is unaware of it.  Therefore, this makes Amarok think that there are no volumes.

End result is that Amarok does not register any devices, the music is stored in the database with a fake ID -1 for a device, and the removable / network collection feature just does not work.

I am sure other applications that use solid to determine the availability of volumes and identification of files per volume will be afflicted with the same malady.

Reproducible: Didn't try



Expected Results:  
Have solid tell client applications of both ZFS file systems and NFS network file systems known to the system / mounted on the system.

What is going on with this bug?

Comment 2 Manuel Amador (Rudd-O) 2011-07-11 12:42:55 UTC

What is going on?

Comment 3 Manuel Amador (Rudd-O) 2011-07-28 06:48:04 UTC

Hello?

If it helps, the systemsettings service manager shows Hardware Detection on-demand service shows as Not Running.

Help?

Bug CONTINUES:


~@karen.dragonfear α:
solid-hardware query 'IS StorageAccess'
udi = '/org/freedesktop/UDisks/devices/sda1'

Comment 5 Manuel Amador (Rudd-O) 2011-08-28 00:08:21 UTC

Same problem, 4.7.0

Comment 6 Manuel Amador (Rudd-O) 2011-11-07 20:56:31 UTC

For comparison, on Ubuntu (Kubuntu kde packages, latest release):

------------------------------


~@arianna.company α:
solid-hardware query 'IS StorageAccess'
udi = '/org/freedesktop/UDisks/devices/sda4'
udi = '/org/freedesktop/UDisks/devices/dm_2d2'
udi = '/org/freedesktop/UDisks/devices/sda1'
udi = '/org/freedesktop/UDisks/devices/sda2'
udi = '/org/freedesktop/UDisks/devices/sda3'
udi = '/org/kde/fstab///10.254.102.1/shared'
udi = '/org/kde/fstab///172.16.1.185/sdcard' <-!!!! SEE?

What is going on with fedora then?
