This topic provides instructions to add additional disk space to the Reporting Engine for large reports. If large compliance reports have to generated for IPDB or Warehouse, the Reporting Engine disk space might get consumed quicker than expected. In such cases, you can mount any external storage such as SAN or NAS for storing reports.
The directories that tend to fill up disk space are resultstore and formattedReports under the Reporting Engine home directory. It is recommended to move only these two directories to SAN or NAS and replace the original locations with soft links pointing to the new locations. It is also recommended to leave the remaining directories in the local disk itself for reliable and high I/O performance.
To move disk space for the Reporting Engine to external storage:
Stop Reporting Engine service as a root user.
Switch to rsasoc user.
Change to RE home directory.
Move the resultstore directory to a mounted external storage. Type the following command and press ENTER:
mv resultstore /externalStorage
Move the formattedReports directory to a mounted external storage. Type the following command and press ENTER:
mv formattedReports /externalStorage
Create a softlink for resultstore. Type the following command and press ENTER:
ln -s /externalStorage/resultstore /home/rsasoc/rsa/soc/reporting-engine/resultstore
Create a softlink for formattedReports. Type the following command and press ENTER:
ln -s /externalStorage/formattedReports /home/rsasoc/rsa/soc/reporting-engine/formattedReports
Exit the rsasoc user.
Start Reporting Engine service as a root user.
Additionally, if you want to store reports beyond 100 days, change the retention configuration appropriately in the Step 2. Configure Reporting Engine Settings.
