Comment 6 for bug 1456276

The thing is there could be a lot of possible reasons why this has happened including this bug https://bugzilla.redhat.com/show_bug.cgi?id=956053 (from logs it is only clear that md device was occupied by something, likely by kernel) and currently Fuel Agent has just rudimentary decommission support. If there had been a kind of a complicated case when, for example, md device is a part of lvm or something like this, we 100% couldn't have been able to deal with that. So, what we actually need for addressing this issue and other ones like this, is to implement comprehensive data driven decommission feature. I believe it is deal of a separate story. Let's move this bug to 7.0.
