Recommended Ocfs2 1.4.1 mount options with DB volumes

(Doc ID 835839.1)

Linux Kernel - Version: 1.4.1 to 1.4.1
Linux x86-64


The "atime" is a new implementation in ocfs2 1.4.1 and onwards which is on by default, any direct IO writes can get locked when a node is dead.
When a node dies, the reads to the database from surviving nodes are frozen
for a longer period than with OCFS2 1.2.
To avoid this it is recommended with all DB volumes you should mount with the "noatime" mount option.
