Facing issue while downloading image on NFS mounted Image datastore

We have successfully created Image datastore in opennebula by mounting “opennebula/image” folder from tintri on OpenNebula frontend server with below configuration.
“nfsserver:/opennebula/image /var/lib/one/datastores/160 nfs defaults,soft,intr,rsize=32768,wsize=32768 0 0”

However, we are facing issue while downloading image on datastore, getting below error.

Fri May 3 11:06:24 2024 : Error copying image in the datastore: INFO: cp: Downloading image https://marketplace.opennebula.io/appliance/ca0a75e0-7ae5-013b-d6ed-7875a4a4f528/download/0 to the image repository qemu-img: Could not open ‘/var/lib/one//datastores/160/69fd4f7e9d796ea83877f0d930c60168’: Failed to lock byte 201: No locks available ERROR: cp: Unknown image format src=https://marketplace.opennebula.io/appliance/ca0a75e0-7ae5-013b-d6ed-7875a4a4f528/download/0
