mount error: mount.nfs: /mnt/pve/common is busy or already mounted (500)

Hello!
I have a problem with accessng to a nfs server from some of my proxmox nodes.
one of nodes is serving the share with nfs, /etc/exports is:

/mnt/nfs04 pve-proxmox03*.domain.local(rw,sync,no_root_squash,no_subtree_check)

It contain few subfolders

common  daily  images  monthly  selectel  weekly

.
And this folders are added as a storages to my cluster like this:

nfs: common
        path /mnt/pve/common
        export /mnt/nfs04/common
        server pve-proxmox03a.domain.local
        maxfiles 1
        options vers=3
        content rootdir,vztmpl,iso,images

I see it mounted with

mount | grep nfs

on all nodes but when i try to access them via proxmox interface i'm getting

mount error: mount.nfs: /mnt/pve/common is busy or already mounted (500)

pveversion is pve-manager/4.2-17/e1400248 (running kernel: 4.4.13-1-pve)

Any advice?

pct set 101 -mp0 mp=/root/some/dir/lxc1,/your/backupc/storage/proxmox
pct set 102 -mp0 mp=/root/some/dir/lxc2,/your/backupc/storage/proxmox
Maybe u need something like this.
for convenience I would use the Proxmox as nfs server
