Symptoms

• After an upgrade fails (for any reason), rerunning the upgrade rarely fails with the following error message in the upgrade log file:

  mount: /installs/update/fix/TODO/<Upgrade File Name>.sfs is already mounted

Cause

This is caused because the failed upgrade was not able to automatically unmount the upgrade file (*.sfs).

Resolution

• Unmount the upgrade file manually using the following command:

  umount /mnt/update

• Rerun the upgrade
