Description of problem:
[root@morph-01 root]# cman_tool join
can't open cluster socket: Address family not supported by protocol
[root@morph-01 root]# echo $?
In this case it could even say something about needing to load the module.
Hopefully expunged all error cases that don't return non-zero.
Please let me know if you find any more...I'm sure you will :)
Checking in join.c;
/cvs/cluster/cluster/cman/cman_tool/join.c,v <-- join.c
new revision: 1.9; previous revision: 1.8
Updating version to the right level in the defects. Sorry for the storm.
