File system creation procedure

  1. Create volume groups

    Two volume groups, pdvg and segvg, are created to contain the /var/pd and /var/psf/segments file systems. Creating separate volume groups helps spread I/O across multiple actuators, which can improve performance. The pdvg volume group contains the important InfoPrint Manager database objects and should be backed up at regular intervals. The segvg volume group contains the segmented print files, and can be considered to be transient data. If you have multiple hard drives available for use with segvg, striping across these disks provides multiple heads accessing the data for faster I/O performance, which is useful when driving high speed/high resolution printers.

    Note: A 128 MB Physical Partition size is recommended for 73.4GB drives. If your server has larger or smaller drives, you should adjust this value proportionally.
