[SOLVED] Mac issues connecting to NFS/ZFS on Proxmox

[SomeUser]

Current version of proxmox, fully updated. Have a zpool with sharenfs enabled. Unable to nfs mount from macOS. Any ideas?

proxmox server IP is 10.100.200.200
zpool is jbod/tank
Mac IP is 10.100.200.100
Mac User is Justme
linux VM on Mac is 10.100.200.101

# zfs set sharenfs=rw@10.100.200.0/24 jbod/tank
# zfs get sharenfs jbod/tank
NAME                 PROPERTY  VALUE              SOURCE
jbod/tank  sharenfs  rw=@10.100.200.0/24  local
# cat /etc/exports
/jbod/tank  10.100.200.0/24(rw)

I can successfully run a linux VM on my Mac and run "mount -t nfs 10.100.200.200:/jbod/tank /mnt/nfs" and it mounts successfully.

However, on my Mac, if I used Connect to Server: nfs://10.100.200.200/jbod/tank, I get an error message:

There was a problem connection to the server "10.100.200.200".

Check the server name or IP address, and then try again.  If you continue to have problems, contact your system administrator.

If I run rpcinfo, showmount, and mount on the Mac:

This mac had no issues doing NFS mounts to solaris11 running on the same physical machine as proxmox previously without issues. I would like to get NFS working again...

Thanks for your help.

Hi,

this problem has nothing to do with Proxmox VE we support only the NFS client.
Maybe the free NASor OMV forum can tell which are the correct setting for a MACOS client.

Found the problem - nfs server was running in secure mode, so the client needed to use the resvport option.

mount -t nfs -o soft,nfsvers=4,proto=tcp,resvport proxmox:/jbod/tank /Volumes/nfs
