What is fencing?
Fencing is the act of forecefully removing a node from a cluster. A node with
OCFS2 mounted will fence itself when it realizes that it doesn't have quorum in
a degraded cluster. It does this so that other nodes won't get stuck trying to
access its resources. Currently OCFS2 will
int dlm_new_lockspace(const char *name, int namelen,
dlm_lockspace_t **lockspace, uint32_t flags, int lvblen);
bu t i can not find where it is implemented when i browse kernel source code.

GFS2 is based on a 64-bit architecture, which can theoretically accommodate an
8 EB file system. However, the current supported maximum size of a GFS2 file
system is 25 TB. If your system requires GFS2 file systems larger than 25 TB,
contact your Red Hat service representative.

1.i need gfs2 or ocfs2 to store xen-disk image file(20G--100G),it is big file.
the underlying storage is fc-san. both of them have cluster sence.so they
fit for me.
if gfs2 is ready for product? anyone use gfs2 in product? stability is the
most important thing.
2.i have try gfs2 and ocfs2
which is better gfs2 and ocfs2?
i want to share fc-san, do you know which is better?
stablility,performmance?

would you give me any suggestion on optimization?

1.if i can deploy gfs2 on fedora12.if it is ok to build from source code ?
2.the max node gfs2 can manger? i use san, if i have 100 machines,if gfs2 can
work over those nodes?
thanks
