Another problem is that you can write multiple addr's to that file sequentially when using SCTP, so which do you get when you read it? > 3.

I suggest this. If you want a way to read them, I'd add a new readonly file addr_list, # cat /config/dlm/<cluster>/comms/<comm>/addr_list AF_INET 192.168.151.1 AF_INET 192.168.151.2 Dave -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
