Receiving the below error or similar when running Smartstor Tool:

It is pretty normal to see the Out of memory error when you run the stock script as it needs to load entire SmartStor data into memory first before executing any commands.
1-Open SmartStorTools.sh in a text editor
2-Look for the below line:JAVA_OPTS=-Xmx512m; export JAVA_OPTS 3-Change to:JAVA_OPTS=-Xmx1500m; export JAVA_OPTS
4-Save the changes and rerun the script
-If the OOM error still happens, just repeat above steps until suitable heap size is found
