After each node change by the linstor controller, the following error appears:
SocketException: Unsupported address type
What could be happening? How can I fix it?
What is a node change?
And where does the error appear?
Hi, thank you for your response.
Every time the controller changes nodes (I have a 3-node cluster), with the drbd-reactor service, the error mentioned appears in the table shown with “linstor error-reports list”
AFIAK this message comes, when the controller tries to bind on the ipv6 socket, but that doesn’t work because ipv6 isn’t configured. then it will fallback to ipv4.
but you would need to share the error-report, to be 100% sure, if thats the case you should be able to directly bind to the ipv4 port and the controller wouldn’t try ipv6

END OF ERROR REPORT
yes, this comes from our HTTP server trying to bind on ::
I guess you can get rid of the error if you add
[http]
listen_addr = "0.0.0.0"
to your /etc/linstor/linstor.toml
Thank you so much for your help.
This change get rid of the error.
