Hello All,

I have created a cluster of 5 Proxmox VEs together. When I am trying to mount an NFS from another server for live migration between the cluster. It shows not online in the storage. Please help me with this?

I have the exact problem. i tried changing nfs version from 3 to 4, that worked on the master node but not the newly added node. After looking around on the forums i tried what others have such as upgrading the packages, rebooting, all without success. Some assistance with this will be greatly appreciated.
