help | ||
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". | ||

config OCFS2_FS_O2CB | ||
tristate "O2CB Kernelspace Clustering" | ||
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 | ||
tristate "OCFS2 Userspace Clustering" | ||
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. | ||
|
||
config OCFS2_FS_STATS | ||
bool "OCFS2 statistics" | ||
depends on OCFS2_FS | ||
default y | ||
help | ||
This option allows some fs statistics to be captured. Enabling | ||
this option may increase the memory consumption. | ||
|
||
config OCFS2_DEBUG_MASKLOG | ||
bool "OCFS2 logging support" | ||
depends on OCFS2_FS | ||
default y | ||
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. | ||
|
||
config OCFS2_DEBUG_FS | ||
bool "OCFS2 expensive checks" | ||
depends on OCFS2_FS | ||
default n | ||
help | ||
This option will enable expensive consistency checks. Enable | ||
this option for debugging only as it is likely to decrease | ||
performance of the filesystem. | ||
|
||
config OCFS2_FS_POSIX_ACL | ||
bool "OCFS2 POSIX Access Control Lists" | ||
depends on OCFS2_FS | ||
select FS_POSIX_ACL | ||
default n | ||
help | ||
Posix Access Control Lists (ACLs) support permissions for users and | ||
groups beyond the owner/group/world scheme. |
