NFS mount with Proxmox VE 4 finds no export

[HBO]

We want to add a backup storage with nfs mount, a manual mount is possible:

mount -t nfs 10.0.10.164:/srv/vmbackups /mnt/test/
10.0.10.164:/srv/vmbackups on /mnt/test type nfs4 (rw,relatime,vers=4.0,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=10.0.10.10,local_lock=none,addr=10.0.10.164)

But in proxmox interface "Storage > add > NFS" we get no entry in "export". A manual entry with "/srv/vmbackups" results in a 500 error.

Is it possible to debug this?

Yep you can try from the command line:

pvesm nfsscan my_nfs_server

and see it it ouputs something

Thanks, the rpcbind service was blocked by centos firewall. Works now.
