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".

depends on OCFS2_FS

default y
|
help
|
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.

config OCFS2_FS_USERSPACE_CLUSTER

depends on OCFS2_FS && DLM
|
default y
|
help
|
This option will allow OCFS2 to use userspace clustering services
|
in conjunction with the DLM in fs/dlm. If you are using a
|
userspace cluster manager, say Y here.
|
|
It is safe to say Y, as the clustering method is run-time
|
selectable.

This option allows some fs statistics to be captured. Enabling

this option may increase the memory consumption.

|
help
|
The ocfs2 filesystem has an extensive logging system. The system
|
allows selection of events to log via files in /sys/o2cb/logmask/.
|
This option will enlarge your kernel, but it allows debugging of
|
ocfs2 filesystem issues.

help
|
This option will enable expensive consistency checks. Enable
|
this option for debugging only as it is likely to decrease
|
performance of the filesystem.
