Rackd not starting because of IPv6


I have installed MAAS 2.9 on CentOS 7 and have created rack init.

The rackd is not starting and I can see in logs error:

OSError: [Errno 97] Address family not supported by protocol

IPv6 is disabled on the server.

How can I fix this?

Many thanks in advance.


I’m pretty sure you are going to need to enable IPv6 on the server. You won’t need to assign any IPv6 addresses to anything, but IPv6 will need to be enabled in the kernel.

MAAS wants to know what IP addresses are on the server’s interfaces and by disabling IPv6, the kernel doesn’t even know enough to be able to tell MAAS that the server has no IPv6 addresses.

Yes, I had to re-enable IPv6. That solve the problem.
