why does using System Manager aws:runShellScript to execute "df -h" not show EFS mounts

Question

When I run the df command on my servers the results displayed show my EFS mounts.  when I run the command using System Manager and doc aws:runShellScript the EFS mounts are not show but all non EFS mounts are shown.  Why is this ? Am I missing a parameter ?  These are RHEL 7.9.

Answer

Hello there,

Thank you for reaching out to us and posting your question in Re:Post. I tested `AWS-RunShellScript` Command document in a RHEL 7.9 instance to run `df -h`. I mounted EFS using both `nfs4` and `efs` filesystem type. In either case the `df -h` command displayed the EFS mounts. You may check:

1. If the EFS filesystem is mounted when the Systems Manager document executes.
2. If you are using the latest Systems Manager agent. Ref: https://docs.aws.amazon.com/systems-manager/latest/userguide/agent-install-rhel.html

If this is reproducible, please feel free to open a Support case with us and we can investigate further.
