NFS Share ( between two VMs )

[friendodevil]

I'm trying to create an NFS share drive between two Ubuntu 20.04 VMs -- so far unsuccessful -- help will be highly appreciated

VM1 (Server)

1. Install NFS srvr package: sudo apt-get install nfs-kernel-server
2. Create share list
   • add to /etc/exports:
   • /mnt/nfs-share 192.168.1.0/24(rw,sync,root_squash,subtree_check)
   • start NFS: sudo service nfs-kernel-server start
3. Did not see Ubuntu complain thus far

Add NFS share drive to Proxmox in Datacenter, exports autofilled nfs-share so I assume VM1 share drive was setup successfully.

VM2 (Client)

1. Install NFS client package: sudo apt-get install nfs-common
2. Create share directory & and mount nfs drive
   • sudo mkdir /mnt/nfs-share-mount
   • edit /etc/fstab:
   • 192.168.1.100:/mnt/nfs-share /mnt/nfs-share-mount nfs rw,soft,intr,noatime,timeo=100,rsize=32768,wsize=32768 0 2

when a running 'mount -a' I get: NFS mount.nfs: access denied by server while mounting.... am I missing some permissions settings anywhere or is it something else?

Check the permissions on the folder you are share .. filesystem permissions .. that's usually what the access denied is from

I think you need:
exportfs -a

 

[CTCcloud]

I've never needed to use "exportfs -a" .. it's just a high-level way of making the changes in /etc/exports active which can also be done with
systemctl restart nfs-kernel-server
... just saying ..

Friendodevil - did you get this working?

Your question/issue does not appear to be PVE specific. There is nothing in Proxmox that you need to "enable" to make NFS work between two VMs.
Have you tried any troubleshooting? I.e. https://www.thegeekdiary.com/mount-nfs-access-denied-by-server-while-mounting-how-to-resolve/

I was finally able to get this going with the following steps:

Installing nfs server

1. sudo apt update
2. sudo apt install nfs-kernel-system -y
3. Make directory : sudo mkdir /mnt/<dir> <<< This should be where the virtual HDD is mounted to via disk mount
4. sudo chmod 755 /mnt/<dir>
5. sudo nano /etc/exports

   1. /mnt/<dir>

      192.168.1.0/255.255.255.0(rw,sync,no_subtree_check)

6. sudo exportfs -arvf
7. sudo systemctl start nfs-kernel-server
8. sudo systemctl enable nfs-kernel-server
9. sudo systemctl status nfs-kernel-server

Installing on Client

1. sudo apt install nfs-common
2. showmount –e <server IP>
3. Sudo mkdir /mnt/nfs-drv
4. sudo nano /etc/fstab

   1. 192.168.1.10:/mnt/<dir>

      /mnt/nfs-drv

      Nfs

      0

      0

5. sudo mount -a
6. Mount
