Subject: [PATCH 242/246] common-ha: explicitly set udpu transport for corosync
|
|
|
3604df |
|
|
|
3604df |
On RHEL7 corosync uses udpu (udp unicast) by default. On RHEL6 the
|
|
|
3604df |
default is (now) udp multi-cast. In network environments that don't
|
|
|
3604df |
support udp multi-cast this causes the ever growing lists of
|
|
|
3604df |
[TOTEM ] Retransmit errors.
|
|
|
3604df |
|
|
|
3604df |
Always specifying --transport udpu is thus a no-op on RHEL7.
|
|
|
3604df |
|
|
|
3604df |
Using the same transport on both RHEL6 and RHEL7 may (or may not
|
|
|
3604df |
give similar behavior and performance--it's hard to say.
|
|
|
3604df |
|
|
|
3604df |
It remains a mystery why things have always worked on RHEL6 prior to
|
|
|
3604df |
now. Further investigation is required to uncover why this is the
|
|
|
3604df |
case.
