|
| |
| This section describes how to create and share a directory using NFS for Slurm cluster clients. The shared folder will reside under /export, mounted from an LVM partition, and made accessible to all compute and service nodes via NFS.
| |
|
| |
| == 1. Create and Mount LVM Partition ==
| |
|
| |
| : Create an ext4 LVM partition with the required space to be shared with clients.
| |
| : Mount the created LVM partition on /export via UUID using /etc/fstab.
| |
|
| |
| == 2. Create Base Directories ==
| |
|
| |
| : Create the home directory inside /export:
| |
| <pre> mkdir -p /export/home </pre>
| |
|
| |
| : You can later add other subdirectories like /export/apps for application binaries, or others as needed.
| |
|
| |
| == 3. Install NFS Server Packages ==
| |
| <pre> apt install -y nfs-kernel-server </pre>
| |
|
| |
| == 4. Configure NFS Exports ==
| |
|
| |
| : Open /etc/exports file and add the following entry:
| |
| <pre> /export <private-subnet>(rw,sync,no_subtree_check) </pre>
| |
|
| |
| : Example for private subnet 192.168.2.0/24:
| |
| <pre> /export 192.168.2.0/24(rw,sync,no_subtree_check) </pre>
| |
|
| |
| '''Note:'''
| |
|
| |
| We are exporting the entire /export directory, not just /export/home.
| |
|
| |
| This gives flexibility to add new folders like /export/apps or others in the future.
| |
|
| |
| If you're using InfiniBand, use the InfiniBand subnet instead of the Ethernet/private subnet in the export entry.
| |
|
| |
| == 5. Apply Export Changes ==
| |
| <pre> exportfs -a </pre>
| |
|
| |
| == 6. Restart the NFS Service ==
| |
| <pre> systemctl restart nfs-kernel-server </pre>
