[Read more]Percona Server’s “crash-resistant replication” feature is useful in versions 5.1 through 5.5. However, in Percona Server 5.6 it’s replaced with Oracle MySQL 5.6′s “crash safe replication” feature, which has it’s own implementation (you can read more about it here).

[Read more]One very interesting feature, “Compact Backup,” is introduced in Percona XtraBackup 2.1. You can run “compact backups” with the –compact option, which is very useful for those who have limited disk space to keep the database backup. Now let’s first understand how it works. When we are using –compact option with Innobackupex, it will omit the secondary index pages.

You can also follow the official documentation here.
The version of Pacemaker (always considered as Technology Preview by RedHat) provided with 6.4 is 1.1.8-x which is not 100% compatible with 1.1.7-x see this report.
