[Tracker] Cannot retrieve USB storage device UUID using Tracker

[Mihai Stoica <mihai stoica gmail com>]

Hi,

I'm using Tracker 0.9.19 in a customized fedora rootfs and I'm trying to index a removable etx3 USB Mass Storage device.

Because automount is disabled I am doing the mount manually in a folder visible to tracker.

The result is as follows:

(tracker-miner-fs:1418): Tracker-DEBUG: Found 'disk' mounted on path '/root/disk'

(tracker-miner-fs:1418): Tracker-DEBUG:   Using filesystem type:'ext3'

(tracker-miner-fs:1418): Tracker-DEBUG:   No UUID, generated:'0432c965ee57d964ec653dd042c74be7' (based on mount path)

(tracker-miner-fs:1418): Tracker-DEBUG:   Adding mount point with UUID:'0432c965ee57d964ec653dd042c74be7', removable: no, optical: o

Tracker-Message: Mount point added for URN 'urn:nepomuk:datasource:0432c965ee57d964ec653dd042c74be7'

On a Ubuntu 10.04 machine I do a similar test with the only difference that USB is automounted, I unmount it and then mount it back in home folder. In this case the result is:

(tracker-miner-fs:15960): Tracker-DEBUG: Found 'medias' mounted on path '/media/tmp'

(tracker-miner-fs:15960): Tracker-DEBUG:   Adding mount point with UUID:'35788862-be8d-4390-836f-6286bcf1e758', removable: yes, optical: no

Tracker-Message: Mount point added for URN 'urn:nepomuk:datasource:35788862-be8d-4390-836f-6286bcf1e758'

Tracker-Message:   Adding directories in removable/optical media to crawler's queue

Doing some investigation I've noticed that call to "g_mount_get_volume (mount)" from tracker-storage.c is always returning NULL in the customized rootfs, so the UUID is always generated and I would really need it to be correctly identified in order to avoid indexing twice of the same device.

I can't figure out what is the source of this behavior, what is the difference on Ubuntu machine against the customized rootfs. HAL daemon is up and running on both, Tracker configuration is the same. A difference is that customized rootfs is using systemd and has automount disabled.

Also on fedora rootfs glib is version 2.10-1.

Do you have any hint or idea about where to start looking for a solution ?

Thank you for helping.
