when we create nfs in another server and mount in controller node , and change the cinder.conf file and when restart service it will dead or disabled each and every time. plz any one provide a perfect solution for that.

both the server has ntp sync. In details we have controller node and other is nfs server with 50GB free space to mount in /cloud in nfs server.And this /cloud is mount in controller node . I change the packstack answer file these options -CONFIG_CINDER_BACKEND=nfs , CONFIG_CINDER_VOLUMES_SIZE=50G , CONFIG_CINDER_NFS_MOUNTS=10.134.10.216:/cloud and then run the packstack answer file . After successfully completion of this , when we see the cinder-manage service list cinder volume service is dead. the output is here.
