Hi Adivya,
not an nfs expert but I'd say vers=4 and nfsvers=4 options are redundant.

Hi Team,
I am trying to configure the Cinder Volume service with NFS server as a backend and this is my user_variables File
cinder_backends: default: volume_backend_name: nfs volume_driver: cinder.volume.drivers.nfs.NfsDriver nfs_shares_config: /etc/cinder/nfs_shares nfs_qcow2_volumes: true nfs_mount_options: vers=4,nfsvers=4,noatime,rw,bg,intr,async,timeo=60 nfs_snapshot_support: true shares: - ip: 172.29.244.103 share: /cinder/volume
My NFS server Configuration is Like this
/img/glance 172.29.244.0/22(rw,insecure,sync,no_subtree_check,no_root_squash) http://172.29.244.0/22(rw,insecure,sync,no_subtree_check,no_root_squash) /cinder/volume 172.29.244.0/22(vrw,insecure,sync,no_subtree_check,no_root_squash) http://172.29.244.0/22(vrw,insecure,sync,no_subtree_check,no_root_squash)
now what i am seeing is below error
