</span>engine-cleanup only cleans up the engine. It does nothing to the hosts.<br>
I am not aware of a similar "vdsm-cleanup" tool.<br>
In principle, you could have moved your hosts to maintenance and removed them<br>
from the engine. No idea what this would tell vdsm to do wrt to your question.<br>
It definitely would not undo ifcfg-* changes.<br>

See also [1], which is for a hosted-engine host, not exactly your case<br>
but similar. You are welcome to comment there, and/or open another RFE<br>
bz for general hosts (not hosted-engine ones).<br>
<br>
I might be wrong, though - perhaps there is something to undo ifcfg*<br>
changes that I am unaware of.
