Hi.

I'm pleased to announce POHMEL high performance network parallel
distributed filesystem.
POHMELFS stands for Parallel Optimized Host Message Exchange Layered File System.

Development status can be tracked in filesystem section [1].

This is a high performance network filesystem with local coherent cache of data
and metadata. Its main goal is distributed parallel processing of data.

This release brings following features:
 * Read requests (data read, directory listing, lookup requests) balancing
 	between multiple servers.
 * Write requests are sent to multiple servers and completed only
 	when all of them sent an ack.
 * Ability to add and/or remove servers from working set at run-time from
	 userspace (via netlink, so the same command can be processed from
	 real network though, but since server does not support it yet,
	 I dropped network part).
 * Documentation (overall view and protocol commands)!
 * Rename command (oops, forgot it in previous releases :)
 * Several new mount options to control client behaviour instead of
	hardcoded numbers.
 * Bug fixes.

Neat :)  Thanks for protocol documentation, too.  Do you plan to add 
write-pages in addition to write-page?  Also, write-page does not appear 
to be documented.

Is race-across-directories race-free?  That is a sticky area, see 
Documentation/filesystems/directory-locking in particular.

With the exception of encryption, do you think the POHMELFS client is 
mostly complete, at this point?
