Subject: [Ocfs2-devel] [PATCH 0/15] ocfs2: Support for discontiguous block group.
Date: Thu, 01 Apr 2010 10:53:40 +0800 [thread overview]
Message-ID: <4BB40AB4.8040205@oracle.com> (raw)
Hi all,
This patch set try to implement discontiguous block group in ocfs2. We
have meet with many ENOSPC problems because of file system fragmentation
and among them a big part is that we can't allocate contiguouse 4M bytes
to allocate a new inode/extent block group. So this patch set is going
to resolve this by supporting discontiguous block group.
01-11 are the original patches from Joel Becker, I didn't touch them so
that Joel could skip them for review. ;)
12 is a patch fixing some tiny problems in 01-11. I separate it out so
that it can be reviewed by Joel easily and it will be integrated into
the previous 01-11 when it get acked.
13-15 are the following patches.

For the design doc, please see

The patches for ocfs2-tools support will be sent to ocfs2-tools-devel.
Regards,
Tao
