Description John Pittman 2016-07-27 20:15:10 UTC
Description of problem:

When using with the --forceremove option, expectation, taken from the --help of the command, is to "Remove and readd every device". Currently, the devices are removed, but we do not readd. Added additional line to ensure readd attempt.

Version-Release number of selected component (if applicable):


How reproducible:

Run ' --forceremove'
Observe devices are removed and not readded

Actual results:

Devices are removed

Expected results:

Devices should be removed and readded as mentioned in the help

Additional info:

Patch to enable readding:

As a note, I submitted the patch upstream on github but never got response.

Hi John Pittman,

Upstream decideded to change help message instead of change action of
`forceremove`, and I would like to keep that way in RHEL 7.

Is that OK to you?

Comment 6 John Pittman 2017-03-13 12:29:08 UTC
Hi Gris.  Yes, that's fine with me.
