    Hi Kaamesh,

    
        Hi Pierre, Im trying to downgrade to 3.6 as suggested by
          you and joe but im having some problems:-
        I have performed the following commands
         

          wget -O - http://download.gluster.org/pub/gluster/glusterfs/3.6/3.6.2/Debian/wheezy/pubkey.gpg
          | sudo apt-key add -

          sudo sh -c "echo 'deb http://download.gluster.org/pub/gluster/glusterfs/3.6/3.6.2/Debian/wheezy/apt
          wheezy main' > /etc/apt/sources.list.d/gluster.list "

           sudo apt-get update 

           sudo apt-get install glusterfs-server=3.6.2-2
        

        The commands run successfully but when i check the version
          of glusterfs using glusterd --version, its still 3.7.6
        Any gluster command i run just prints "Segmentation Fault"
        Any ideas?
        Thanks, 
        Kaamesh

        
    OK, stop me I am wrong, but you have system based on the debian
    track as ubuntu. Here in our Department  we don't support the debian
    track. But, may be you have a sort of artefact of de- installing the
    preceding releases.

    
    I get that sort of problem on my centos6.7

    
    So my answer will be the direct answer for you. But analyse the
    process. When I want to change the glusterfs release I do the
    following actions :

    
      first : yum list | grep gluster. then I get the list of the
        package to erase ;
      So I erase the package with rpm -e --nodeps ; ;
      And redo the : yum list | grep gluster, and discover that
        older package where not erase. Then I erase them with rpm -e
        --nodeps package-release

      
      Then I get a proper and stable package installation ;
      So, now I can install the new release with the following
        script, in the directory containing the good release. :
      
        for i in *.rpm ;do
        rpm -i --nodeps $i
        ;done
      
    
    Have a good attention on the /var/lib/glusterd peers files for
      all of your nodes and the /var/lib/glusterd/gluster.info file.
      that is  the only way to get back yours volume and files. May be
      have a specific attention to the release of glusterfs in all that
      files. For 3.6.6 its 

    
    operating-version=30600

    
    OK You may read that that number release is the the most
      appropriate. But it is the number installed with te 3.6.6 release.
      There are numbers of answer concerning that kind of number.

    
    I hope that these answer will help you. I will be back to my
      office tomorrow . don't hesitate to ask for more information.

    
    Another point. If you mount your glusterfs volume on all your
      node don't use NFS. I get a lot of problems. I think that these
      problems arrived with file locking, but I have no time today to
      search for that. So do a glusterfs fuse mount.

    
    Good luck

    
      Pierre Léonard.
