High load on CPU due to glusterfsd process
Hi Team,
Whenever I am performing the IO operation on gluster volume, the loads is
getting increase on CPU which reaches upto 70-80 sometimes.
when we started debugging, found that the io_worker thread is created to
server the IO request and consume high CPU till that request gets completed.
Could you please let me know why io_worker thread takes this much of CPU.
Is there any way to resole this?

improve use_mm / unuse_mm
Hi all,
this series improves the use_mm / unuse_mm interface by better
documenting the assumptions, and my taking the set_fs manipulations
spread over the callers into the core API.

Unable to load Models which reference plugins?
I''m using a plugin which adds a method to ActiveRecord::Base
http://similetimelinerailshelper.googlecode.com/svn/trunk/simile_timeline/
This adds an "acts_as" type declaration to the Models, via the file in
vendor/plugins/simile_timeline/lib/simile_timeline.rb Rails is working
with these declarations, and they are being used successfully in
