+## nfs
+***in proxmox shell:***
+```
+# apt install nfs-common
+# apt install nfs-kernel-server
+# mkdir -p /mnt/shared_folder_on_nfs
+# chmod -R 777 /tank/diskstorage
+# chown -R nobody:nogroup /tank/diskstorage
+```
+***create zfs shared folder:***
+```Bash
+# zfs create tank/nfs_shared_folder
+# zfs set sharenfs=on tank/nfs_shared_folder
+```
+***edit the exports file:***
+```Bash
+# nano /etc/exports
+```
+>```
+>...
+># /srv/nfs4/homes  gss/krb5i(rw,sync,no_subtree_check)
+>#
+>/proxmox.local:/tank/nfs_shared_folder *(rw,sync,no_subtree_check)
+>```
+***edit the fstab:***
+```Bash
+# nano /etc/fstab
+```
+>```
+>...
+>proc /proc proc defaults 0 0
+>
+>proxmox.local:/tank/diskstorage /mnt/shared_folder_on_nfs nfs auto 0 0
+>```
+***update Grub:***
+```Bash
+#sudo apt-get install --reinstall dracut
+#dracut -f
+```
+***edit the wm-config:***
+- this needs to be done in the machine that runs libvirt not inside proxmox
+```Bash
+# virsh edit <your_proxmox_wm>
+```
+
+> - add `<shareable/>` to the disk we added to create the zfs tank
+> ```
+>      <disk type='block' device='disk'>
+>      <driver name='qemu' type='raw' cache='none' io='native' discard='unmap'/>
+>      <source dev='/dev/sdc'/>
+>      <target dev='sdc' bus='sata'/>
+>      <shareable/>
+>      <address type='drive' controller='0' bus='0' target='0' unit='2'/>
+>      </disk>
+>```
+
+
+***we can mount the zfs tank thats is shared via nfs like this:***
+```
+# mount -t nfs 192.168.122.166:/<mountpoint> /mnt/shared_folder_on_nfs
+```
