File system configuration planning

Ricoh recommends that the file systems be mirrored on a shared Storage Across Network (SAN) in order to eliminate as many SPOFs as possible.

InfoPrint Manager shared file systems include these:

  • /var/pd
  • /var/psm
  • /var/psf
  • /var/psf/segments (do not mirror this file system)
  • /var/pddir/

You must create these files systems before installing InfoPrint Manager. If they are already available at installation time, InfoPrint Manager detects the listed file systems and uses them to install the required files.

If your InfoPrint Manager for Linux installation drives printers that use either the CUPS, BSD, or PSF-Other device support systems (DSSs), make sure that you synchronize the /etc/cups directory on both systems, or allow it fail over. This directory contains critical device files that cannot be relocated, but must be identical on both your primary and back-up nodes. Even though these are Linux system files and not InfoPrint Manager files, InfoPrint Manager uses data to these files that is critical to ensuring that certain printers appear on your failover system. If this directory is not synchronized, certain InfoPrint Manager actual destination objects may have to be deleted and redefined each time you failover.
