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)
/cinder/volume 172.29.244.0/22(vrw,insecure,sync,no_subtree_check,no_root_squash)

now what i am seeing is below error

2024-06-24 08:11:42.892 4807 ERROR cinder.volume.drivers.remotefs [None req-85e0d72a-f403-4c8e-8880-1ced0413f760 - - - - - -] Exception during mounting NFS mount failed for share 172.29.244.103:/cinder/volume.

Any clue on this, How to fix it
