[PATCH 0/3] ocfs2: Switch over to JBD2.
ocfs2 currently uses the Journaled Block Device (JBD) for its
journaling. This is a very stable and tested codebase. However, JBD
is limited by architecture to 32bit block numbers. This means an ocfs2
filesystem is limited to 2^32 blocks. With a 4K blocksize, that's 16TB.
People want larger volumes.
Fortunately, there is now JBD2. JBD2 adds 64bit block number support
and some other

[PATCH 0/3] ocfs2-1.4: Backport inode alloc from mainline.
Hi all,
this patch set are the backport of inode alloc improvement from
mainline to ocfs2-1.4.
the patches are almost the same excpet one thing:
Joel has added JBD2 support to ocfs2, so he has added "max_blocks" to
alloc_context and add a new function
"ocfs2_reserve_clusters_with_limit". We don't have that in ocfs2-1.4. So
there are some great difference in patch 2.

[PATCH 1/3] ocfs2: Optimize inode allocation by remembering last group.
In ocfs2, the inode block search looks for the "emptiest" inode
group to allocate from. So if an inode alloc file has many equally
(or almost equally) empty groups, new inodes will tend to get
spread out amongst them, which in turn can put them all over the
disk. This is undesirable because directory operations on conceptually
"nearby" inodes force a large number of seeks.
So

[PATCH 0/40] ocfs2: Detach ocfs2 metadata I/O from struct inode
The following series of patches attempts to detach metadata I/O from
struct inode. They are currently tied together pretty tightly.
Metadata reads happen via the ocfs2_read_blocks() functions, writes via
both jbd2 and ocfs2_write_blocks().
- Each inode has a cache of associated metadata blocks stored on its
ip_metadata_cache member. The ocfs2_read/write_blocks() functions
take a struct

[git patches] Ocfs2 updates for 2.6.30
Hi,
The following patches comprise the bulk of Ocfs2 updates for the
2.6.30 merge window. Aside from larger, more involved fixes, we're adding
the following features, which I will describe in the order their patches are
mailed.
Sunil's exported some more state to our debugfs files, and
consolidated some other aspects of our debugfs infrastructure. This will
further aid us in debugging

[PATCH 0/3] ocfs2: Inode Allocation Strategy Improvement.v2
Changelog from V1 to V2:
1. Modify some codes according to Mark's advice.
2. Attach some test statistics in the commit log of patch 3 and in
this e-mail also. See below.
Hi all,
In ocfs2, when we create a fresh file system and create inodes in it,
they are contiguous and good for readdir+stat. While if we delete all
the inodes and created again, the new inodes will get spread out and
