Dear Vijay, Craig I installed glusterfs's latest version in 2 VMs and tried Alfresco with it, the VMs where configured as replication. The result is that it worked as smoothly as it should be. It seems the lock problem was due to the old version. I didn't try it with distribution and replication as my working environment is, but I think it should work normally. I'll do this test early today and post my results. Note: I've attached the vol files and alfresco log. In Alfresco log you may find many errors, but they're not related to GlusterFS, they're due to bad Alfresco's configuration (no time to tweak :) ). The errors related to it (IO, NIO, lock) aren't there any more :) Thank you again both of you and any one who helped.
