Environment

VMware Aria Automation Config 8.x

Cause

The issue occurs on Linux systems when the installation path's mount (such as /tmp or /var) has the noexec flag set.

Resolution

The solution requires mounting the /tmp or /var directories with execute permission specifically for the Raas installation process.

Follow the below steps to provide executable permission for /tmp or /var.

1. SSH to the server on which the RAAS installation is performed.
2. Using the below command to display the mount point properties

    mount
   
3. If the /tmp or /var filesystem is mounted with the "noexec" option, remount it with exec permission using the following command:
   
    sudo mount /tmp -o remount,exec
  sudo mount /var -o remount,exec 

    Also update the "/etc/fstab" file entry towards "/var" to have "exec" permission.

4. Restart the RAAS installation. Migrate Aria Config from LCM Based Deployment
5. Once the installation is completed you may change the mount option to "noexec".

  sudo mount -o remount,noexec /tmp
  sudo mount -o remount,noexec /var

    Also update the "/etc/fstab" file entry towards "/var" to have "noexec".
