CONFIG_OCFS2_FS_O2CB: O2CB Kernelspace Clustering

General informations

The Linux kernel configuration item CONFIG_OCFS2_FS_O2CB has multiple definitions:

O2CB Kernelspace Clustering found in fs/Kconfig

The configuration item CONFIG_OCFS2_FS_O2CB:

• prompt: O2CB Kernelspace Clustering
• type: tristate
• depends on: CONFIG_OCFS2_FS
• defined in fs/Kconfig
• found in Linux kernels: 2.6.26–2.6.28
• modules built: ocfs2_dlm, ocfs2_dlm, ocfs2_dlmfs, ocfs2_dlmfs

Help text

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.
