Fixed Compute NFS Share

GAIA Node 01 exposes an NFS share which is mapped into the cluster as fixed-compute-nfs-server.

Setup Routine

NFS server it is. Getting this up and running quickly is priority.

1. Install the nfs server on the host. I chose gaia-node-01 as host; it’s intended to always be on.
2. Install the client on all the nodes.
3. Create the NFS share on the host.
4. Add to exports

Gaianode01 disk setup:

From the disk setup it appears appropriate to reuse the pve-data LVM / pve volume group

lvcreate -V 100G -n fixed-compute-nfs -T pve/data

mkfs.ext4 /dev/pve/fixed-compute-nfs

# <file system> <mount point> <type> <options> <dump> <pass>
/dev/pve/root / ext4 errors=remount-ro 0 1
UUID=0C54-E036 /boot/efi vfat defaults 0 1
/dev/pve/swap none swap sw 0 0
proc /proc proc defaults 0 0
/dev/pve/fixed-compute-nfs  /mnt/fixed-compute-nfs  ext4  defaults  0

This node is permanently exposed at 192.168.50.5.

I added /etc exports:

root@gaianode01:~# cat /etc/exports
# /etc/exports: the access control list for filesystems which may be exported
#               to NFS clients.  See exports(5).
#
# Example for NFSv2 and NFSv3:
# /srv/homes       hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check)
#
# Example for NFSv4:
# /srv/nfs4        gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check)
# /srv/nfs4/homes  gss/krb5i(rw,sync,no_subtree_check)
#
/mnt/fixed-compute-nfs 192.168.50.0/24(rw,sync,no_subtree_check)

I gave standard NFS permissions

chmod -R 777 /mnt/fixed-compute-nfs/
chown -R nobody:nogroup /mnt/fixed-compute-nfs/

I am adding an NFS server using the proxmox cluster > storage > add functionality named fixed-compute-nfs-server
