Swift seems like providing virtual block pool similar to ZFS.

So it may be able to be worked on any existing filesystems such as ext3 and
XFS.

I think that it is not a kind of CFS(Cluster File System), so the
filesystem with Swift is just local filesystem.

The local filesystem won’t share any blocks(or objects) with any
filesystems made by other users as far as Swift does not use CFS like GFS
or GlusterFS.

In the low level of block or object, Swift will be good to provide
availability, replication, and something like that across racks in
datacenter.

But in the high level such as filesystem, I think that CFS-like filesystem
is needed to leverage Swift’s advantages.

Is there any idea?
