Dollar Universe installation on AWS EFS returns a negative value for the available disk space


Article ID: 252751

CA Automic Dollar Universe


The installation or upgrade of a Dollar Universe on a AWS EFS fails due to the space check:

DUAS root directory (full path) [/var/opt/AUTOMIC/DUAS/OBP600_dusnode] : /universe_shared/DUAS/OBP600_dusnode

Not enough disk space (-11217920 MB available), please ensure a minimum of 390 MB.

This is wrong as the EFS service that handles AWS file systems offers nearly unlimited space.

In fact, the target filesystem had 11 TB of  free space. It is much bigger than 390 MB that are necessary for the deployment of DUAS.

The Dollar Universe installation routine is unable to calculate the correct free space size on such Filesystem.


Release : 6.x and 7.x

Component: Dollar Universe Application Server

OS: Linux/Unix


This is defect of the DUAS installation program


Update to a fix version listed below or a newer version if available.

Fix version(s): 
Component: Application Server (Node)
Dollar Universe 7.0.11 - Planned to be released in February 2023
Dollar Universe 6.10.111 - Planned to be released in April 2023

Additional Information

A possible workaround may consists (provided by user that experienced the problem) in installation DUAS on a local file system and copying on a mounted AWS file system.

- Assume the shared filesystem is /universe_shared and the root installation path is /universe_shared/DUAS
- Create a local filesystem to replace /universe_shared
- Install DUAS
- cp -pr /universe_shared/DUAS to another local filesystem
- Unmount /universe_shared
- Mount AWS/EFS as /universe_shared/
- cp -pr to /universe_shared/DUAS
