Red Hat Bugzilla – Bug 498090
Add to documentation on cluster setup
Last modified: 2012-09-21 08:57:56 EDT
Description of problem:
A couple clarifications on the documentation in section 7.1 (Messaging Clusters), "Starting the AIS service":
* at the end of number 3., the line reads "The subnet is the bitwise AND of the mask and the local address, 192.168.1.255". The mask is 255.255.255.0 and the local address is 192.168.1.103, so the bitwise AND should be 192.168.1.0, not 192.168.1.255.
* from the example in number 2., the mcastport setting (in this case 5405) requires that your firewall is set up to allow port 5405/udp. Otherwise the ais service won't start correctly.
Version-Release number of selected component (if applicable):
1.1 Messaging User Guide
This now says the following:
The bindnetaddr entry should be set to the subnet you will use for cluster multicast. Use the same subnet for for all hosts in the cluster. You can find the subnet with /sbin/ifconfig. For example:
# /sbin/ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:1E:37:88:72:8A
inet addr:192.168.1.103 Bcast:192.168.1.255 Mask:255.255.255.0
In this case the local address is 192.168.1.103 and the subnet mask is 255.255.255.0. The bindnetaddr should be set to the bitwise AND of the mask and the local address. For this example, it is 192.168.1.0.
Closed as fix already implemented
Also closed due to bug being against unsupported book version and to clear off docs bug radar. If still applicable against current version (2.0), feel free reopen bug.
