It would be better anybody can provide the steps to setup NFS shared datastore. Error on creating vm > > error: Cannot access storage file ‘/var/lib/one//datastores/125/31/disk.1’: Permission denied We mounted the NFS share from opennebula frontend server to all open nebula nodes. I’m not sure how to setup NFS share in open nebula as shared datastore and how VMs can be migrated without any fail. Mounted NFS volume like below, mount -t nfs 192.168.207.20:/var/lib/one/ /var/lib/one/ Once mounted, /var/lib/one/ will be readonly.

Hi @Jinesh_Ks It seems that you don’t have write permissions on `/var/lib/one`. Check your exports (`/etc/exports`) and see if you have rw permissions on that directory. Also, maybe this guide [https://docs.opennebula.org/5.6/deployment/open\_cloud\_storage\_setup/fs\_ds.html](https://docs.opennebula.org/5.6/deployment/open_cloud_storage_setup/fs_ds.html) can help you.
