Mount additional FSx Filesystem

Ok, so let's say you want to mount an additional FSx Lustre filesystem, to do this you'll need to modify your lifecycle scripts:

  1. Start by modifying the lifecycle_script.py to add your additional FSx filesystems. These can be mounted by adding in lines on lifecycle_script.py#L153 like so. Note you may need to remove the original mount (/fsx) lines so your mount paths don't conflict.
-    fsx_dns_name, fsx_mountname = params.fsx_settings
-    if fsx_dns_name and fsx_mountname:
-        print(f"Mount fsx: {fsx_dns_name}. Mount point: {fsx_mountname}")
-        ExecuteBashScript("./mount_fsx.sh").run(fsx_dns_name, fsx_mountname, "/fsx")
+   ExecuteBashScript("./mount_fsx.sh").run("fs-05dac34e835f2c48f.fsx.us-west-2.amazonaws.com", "4owupbev", "/fsx/home")
+   ExecuteBashScript("./mount_fsx.sh").run("fs-0972ef1ec89bcc14c.fsx.us-west-2.amazonaws.com", "6eoi7bev", "/fsx/mount2")
+   ExecuteBashScript("./mount_fsx.sh").run("fs-0da5542b6a0808375.fsx.us-west-2.amazonaws.com", "yioi7bev", "/fsx/mount3")
  1. (Optional) If you changed the /fsx mount, you'll need to modify fsx_ubuntu.sh to move the home directory from /home/ubuntu to /fsx/home/ubuntu:
#!/bin/bash

# move the ubuntu user to the shared /fsx filesystem
- if [ -d "/fsx/ubuntu" ]; then
-    sudo usermod -d /fsx/ubuntu ubuntu
- elif [ -d "/fsx" ]; then
-    sudo usermod -m -d /fsx/ubuntu ubuntu
- fi
+ if [ -d "/fsx/home/ubuntu" ]; then
+    sudo usermod -d /fsx/home/ubuntu ubuntu
+ elif [ -d "/fsx/home" ]; then
+    sudo usermod -m -d /fsx/home/ubuntu ubuntu
+ fi
  1. Next upload these files and create your cluster. You should see the changes reflected in df -h. Voila!
$ df -h
