RHBA-2015:1789 - corosync bug fix update
Synopsis
corosync bug fix update
Type/Severity
Bug Fix Advisory (none)
Topic
Updated corosync packages that fix two bugs are now available for Red Hat Enterprise Linux 7.
Description
The corosync packages provide the Corosync Cluster Engine and C APIs for Red Hat Enterprise Linux cluster software.
This update fixes the following bugs:
-
In previous versions of Corosync, real time (RT) scheduling priority was not enabled by default. This could increase the possibility of token losses when systems were under heavy CPU load. This change enables RT scheduling for Corosync by default, which reduces the chance of token losses. (BZ#1260002)
-
Prior to this update, in clusters with an odd number of nodes that had the auto_tie_breaker option enabled, when one of the nodes failed, the remaining nodes were split 50:50. Consequently, auto_tie_breaker was not invoked and a random half of the cluster was fenced, rather than the half that did not contain the tie breaker node. With this update, the wait_for_all option is required for clusters with an odd number of nodes. As a result, the cluster half that does not contain the tie breaker node is now fenced in the described scenario. (BZ#1260719)
Users of corosync are advised to upgrade to these updated packages, which fix these bugs.
Solution
