Yes.<br>
<br>
It is not well-tested yet, but that is the intention behind it. The<br>
details are a bit more complex (e.g., the controller can select the<br>
network interface that it uses for communication with the satellite, and<br>
that can be a different one than those used for connecting DRBD<br>
resources, etc...).<br>
<br>
I have used this command in the past to change resource configurations<br>
from Ethernet to Infiniband, from IPv4 to IPv6, etc., so that's all<br>
supposed to work.<br>

<br>
Yes<br>
