Subject: [GIT PULL] Ceph distributed file system client for 2.6.33
Hi Linus,
Please pull from 'master' branch of
git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client.git master
to receive the Ceph distributed file system client. The fs has made a
half dozen rounds on linux-fsdevel, and has been in linux-next for the
last month or so. Although review has been sparse, Andrew said the code
looks reasonable for 2.6.33.
The git tree includes the full patchset posted in October and incremental
changes since then. I've tried to cram in all the anticipated protocol
changes, but the file system is still strictly EXPERIMENTAL and is marked
as such. Merging now will attract new eyes and make it easier to test and
evaluate the system (both the client and server side).
Basic features include:
* High availability and reliability. No single points of failure.
* Strong data and metadata consistency between clients
* N-way replication of all data across storage nodes
* Seamless scaling from 1 to potentially many thousands of nodes
* Fast recovery from node failures
* Automatic rebalancing of data on node addition/removal
* Easy deployment: most FS components are userspace daemons

Thanks-
