[Gluster-devel] Problem with little write/read files in Gluster 3.0.0

Hi all,

I have a problem here. I am using a gluster file system as a simple
distributed storage (one storage server and multiple clients). I want to
put php sessions inside this partition. 

In GlusterFS 2.0.9, it worked very well. PHP could write and read as
quickly as possible. But in 3.0.0, PHP successfully writes files but can
not read anything and freezes (juste after the writing). However, the
gluster partition remains available et readable. Juste the quick
write/read seems not to work.

As anyone already encountered this problem ?

Thanks for your help !

glusterfsd.vol :
volume posix1
  type storage/posix
  option directory /data

Best regards.
