Known Issues:

• The following configuration changes are necessary for ‘qemu’ and ‘samba vfs plugin’ integration with libgfapi to work seamlessly:
  
  1. gluster volume set <volname> server.allow-insecure on
  2. restarting the volume is necessary
     

      gluster volume stop <volname>
      gluster volume start <volname>
     

  3. Edit /etc/glusterfs/glusterd.vol to contain this line:
     

      option rpc-auth-allow-insecure on
     

  4. restarting glusterd is necessary
     

      service glusterd restart
     

     More details are also documented in the Gluster Wiki on the Libgfapi with qemu libvirt page.

• For Block Device translator based volumes open-behind translator at the client side needs to be disabled.
  

  gluster volume set <volname> performance.open-behind disabled
  

• libgfapi clients calling glfs_fini before a successfull glfs_init will cause the client to hang as reported here. The workaround is NOT to call glfs_fini for error cases encountered before a successfull glfs_init. This is being tracked in Bug 1134050 for glusterfs-3.5 and Bug 1093594 for mainline.
• If the /var/run/gluster directory does not exist enabling quota will likely fail (Bug 1117888).
