OCFS2 is a general purpose extent based shared disk cluster file
|
|
|
|
|
system with many similarities to ext3. It supports 64 bit inode
|
|
|
|
|
numbers, and has automatically extending metadata groups which may
|
|
|
|
|
also make it attractive for non-clustered use.
|
|
|
|
|
|
|
|
|
|
You'll want to install the ocfs2-tools package in order to at least
|
|
|
|
|
get "mount.ocfs2".

OCFS2 includes a simple kernelspace clustering package, the OCFS2
|
|
|
|
|
Cluster Base. It only requires a very small userspace component
|
|
|
|
|
to configure it. This comes with the standard ocfs2-tools package.
|
|
|
|
|
O2CB is limited to maintaining a cluster for OCFS2 file systems.
|
|
|
|
|
It cannot manage any other cluster applications.
|
|
|
|
|
|
|
|
|
|
It is always safe to say Y here, as the clustering method is
|
|
|
|
|
run-time selectable.

This option will allow OCFS2 to use userspace clustering services

userspace cluster manager, say Y here.
