Installation of WebSphere Application Server fails with, INST0027E: Insufficient Disk Space to install selected components
 Technote (troubleshooting)
 
Problem(Abstract)
Installation of IBM® WebSphere® Application Server fails to install even though the file system has proper read and write permissions, installation is performed with proper user authority, and there is space in the file system for the installation and temporary files.
 
Cause
As part of its installation or configuration process, other products or the file system installed on the system, might have added directories to the PATH statement. As a result, this will override the file system utilities which the installer is attempting to use.
The following error messages are a result:

Review of the /opt/app directory shows that there was sufficient space available for installation.

Resolving the problem
The following is an example of a PATH variable that has other directories in the PATH statement that override the file system utilities the installer was trying to use:
PATH=/usr/kerberos/sbin:/usr/kerberos/bin:/etc/vx/bin:
/opt/VRTS/bin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local
/bin:/usr/local/sbin:/usr/bin/X11:/usr/X11R6/bin:/root/bin

The PATH variable needs to have the file system utilities in the PATH statement first. The PATH variables need to be reordered to put the system file systems first. Issue the following command:

export PATH=/bin:/sbin:/usr/bin:/usr/sbin:$PATH

Now, the reordered PATH variable looks like the following:

PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/kerberos/sbin:
/usr/kerberos/bin:/etc/vx/bin:/opt/VRTS/bin:/bin:/sbin:
/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/usr
/bin/X11:/usr/X11R6/bin:/root/bin

Now the installer is able to access the file system utilities and the installation completes successfully.
