Description Jan Synacek 2014-04-02 07:47:22 UTC 
Description of problem:
Consider the following python code:
import blivet
b = blivet.Blivet()
b.reset()
[d.name for d in b.devices]
[d.name for d in b.thinpools]
[d.name for d in b.thinlvs]

On my rawhide machine (updated Apr 1 2014), this code prints:
['sda', 'sda1', 'sda2', 'sr0', 'vda', <lot of vda/vdb/vdc devices>]
[]
[]

However, I do have thin pools and thin lvs on my system:

On my RHEL7 testing machine, the code prints:

['rhel', 'rhel-root', 'rhel-swap', 'sr0', 'vda', 'vda1', 'vda2', 'vdb', 'vdb1', 'vgtest', 'vgtest-testlv', 'vgtest-testpool']
['vgtest-testpool']
['vgtest-testlv']

Version-Release number of selected component (if applicable):
python-blivet-0.46-1.fc21.noarch (Rawhide)
python-blivet-0.18.32-1.el7.noarch (RHEL7)


Actual results:
blivet.devices doesn't contain all devices and blivet.thinpools/blivet.thinlvs doesn't work.


Expected results:
blivet.devices contains all devices and blivet.thinpools/blivet.thinlvs list thin pools and lvs correctly.

I just tried this on master and it worked as expected, ie: I could not reproduce this. 

>>> import blivet
>>> print blivet.__version__
0.62
>>> b = blivet.Blivet()
>>> b.reset()
>>> [d.name for d in b.devices]
['btrfs.85', 'fedora', 'fedora-data', 'fedora-home', 'fedora-root', 'fedora-swap', u'sda', u'sda1', u'sda2', u'sda3', u'sdf', u'sdf1', u'sdf2', u'sr0', 'testvg', 'testvg-pool1', 'testvg-thin1']
>>> [d.name for d in b.thinpools]
['testvg-pool1']
>>> [d.name for d in b.thinlvs]
['testvg-thin1']


Does it work for you now as well?
Comment 2 Jan Synacek 2014-09-01 07:28:49 UTC 
Yes, version 0.62 works. Thanks!
