What you will practise

  • Extend a logical volume and its filesystem online
  • Export a directory read-only over NFS
  • Mount an NFS export persistently

Start this lab

With the CLI installed and signed in, this command provisions a fresh Ubuntu 24.04 LTS virtual machine on your Mac, applies the scenario setup and prints the task below.

goldenkube start lfcs-sto-002

Task

The task text exactly as the CLI shows it. Solve it on the machine, then run goldenkube submit.

The ext4 filesystem on the logical volume vault/docs (300 MiB) is mounted at /srv/docs and nearly full. 1. Grow the logical volume to 600 MiB and the filesystem with it, while it stays mounted. The data on it must be preserved. 2. Export /srv/docs/shared over NFS to the client 127.0.0.1, read-only. The export and the NFS server must survive a reboot. 3. Mount that export at /mnt/shared, persistently through /etc/fstab.
