    Hi,

    have a look in the log files /var/log/glusterfs/*

    Seem you have network problem from primarygluster to
    secondarygluster host or process glusterfsd in ono of the host is
    now correctly running.

    If you make a df -h /export/sdb2/brick2 in the two master I aspect
    1GB for each brick. Is it correct?

    Cheers

    Sergio

        Hello team,
         
        I am using gluster as backend for openstack
          cinder. I have created the distributed volume using glusterfs.
         
        I am trying to attach this volume to
          openstack instance. 
          
         
        #gluster volume create test-volume 
          transport tcp primarygluster:/export/sdb2/brick2
          secondarygluster:/export/sdb2/brick2

        root@primarygluster:/export/sdb2/brick2#
         
        issue is if I create a 2GB distributed
          volume , on one of the nodes brick  its showing only 1.1GB and
          I am able to use only 1.1GB , even though I have created 2GB
          volume.
         
        To test that I wrote file more then 1GB ,
          nut I am able to write only 1.1GB.. why my data is not writing
          on another gluster node? 
          
         
        Please assist me if I have missed any
          configuration.
