This patch fixes typos in various Documentation txts. The patch addresses some +words starting with the letters 'U-Z'. Looks like I made it through the alphabet...just in time to start over again +too! Maybe I can fit more profound fixes into the next round...? Time will +tell. :) Signed-off-by: Matt LaPlante <kernel1@cyberdogtech.com> Acked-by: Randy Dunlap <rdunlap@xenotime.net> Signed-off-by: Adrian Bunk <bunk@stusta.de>

OCFS2 filesystem
|
|
==================
|
|
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" and "ocfs2_hb_ctl".

Caveats
|
|
=======
|
|
Features which OCFS2 does not support yet:
|
|
- sparse files
|
|
- extended attributes
|
|
- shared writable mmap
|
|
- loopback is supported, but data written will not
|
|
be cluster coherent.
|
|
- quotas
|
|
- cluster aware flock
|
|
- cluster aware lockf
|
|
- Directory change notification (F_NOTIFY)
|
|
- Distributed Caching (F_SETLEASE/F_GETLEASE/break_lease)
|
|
- POSIX ACLs
|
|
- readpages / writepages (not user visible)
|
|

Mount options
|
|
=============
|
|
|
|
OCFS2 supports the following mount options:
|
|
(*) == default
|
|
|
|
barrier=1 This enables/disables barriers. barrier=0 disables it,
|
|
barrier=1 enables it.
|
|
errors=remount-ro(*) Remount the filesystem read-only on an error.
|
|
errors=panic Panic and halt the machine if an error occurs.
|
|

|
|
nointr Do not allow signals to interrupt cluster
