Unable to mount nfs datastore

[captain118]

I have two nfs datastores one mounts the other one does not.

I am using the IP address not the host name to mount.

I can mount the nfs share using the linux mount command line.

I can add it using the gui but it never goes active.

The rpcinfo command works and returns:

showmount -e 10.9.0.240
Export list for 10.9.0.240:
/mnt/Vol0/NFSDataStore 10.9.0.0

Any help would be greatly appreciated! I really need to get these VMs back up.

Sometimes the showmount command times out:
showmount -e 10.9.0.240
rpc mount export: RPC: Timed out

all the other commands consistently work

hi
the showmount command has to work for the NFS store to be active on the Proxmox side (we use it to check for NFS availability )
try this command

pvesm nfsscan <IP_OF_NFS_SERVER>

it needs to work properly ( this uses showmount in the background)

if the command times out, try to execute the same command locally on your NFS server

showmount -e localhost
