I am pleased to announce the second testing (Alpha 2) release of
Corosync 3.0 (codename Camelback) available immediately from our website at
http://build.clusterlabs.org/corosync/releases/ as corosync-2.99.1.
Corosync is now using kronosnet CI, so you can download RPMs for various
distributions from https://kronosnet.org/builds/.
There are two big changes compared to Alpha 1:
1.) With Knet transport, it's now possible to remove ring0_addr from
corosync.conf and as long as there is other ring (ring1_addr),
everything should work as expected.
This small feature required HUGE amount of work (thank you Chrissie)
mostly in totem subsystem. As a result, Totem no longer addresses nodes
by ring0_addr IP, but only by node id. This makes packet smaller
(especially for bigger clusters).
Ability to remove ring0_addr also brings another problem: how to find
local node in corosync.conf. We've decided to compare hostname with
nodelist.node.name cmap keys. Using hostname is now preferred, but old
style can still be used if ring0_addr exists.
One of the drawbacks is that we need to change on-wire protocol so Alpha
2 is wire incompatible with Alpha 1 (and any other version).
For more details and information about configuration please see updated
2.) Because on-wire was already incompatible we've decided replace
endian_detector with magic number and version. This allows Needle (with
already included patch) to detect that other side is Corosync 3 and
display informative message (now finally also with IP of sender).
