Passed 2/5 RHCA: EX436 Clustering and Storage Management

EX436 is easier than EX442(System Monitoring and Performance Tuning), because testing subjects are less and the method of testing is just straight forward setup and configuration, unlike EX442, which requires extensive analysis and calculation.
I didn't pay attention to RHEL release during exam, But,RHEL 5.4,is showed in my exam result. Although GFS2 is default starting from RHEL 5.3, GFS is the subject to be tested. I think it won't  be changed until RHEL 6 courseware comes out.

My blog post for EX436 study notes

GFS(Global File System) quickstart

RHCS(Red Hat Cluster Suite) quorum disk

RHCS(Red Hat Cluster Suite) I/O fencing using SNMP IFMIB

Do we really need to set partition type to fd(Linux auto raid) for Linux software RAID?
