File system creation procedure
- Create volume groups
Two volume groups,
pdvg
andsegvg
, 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. Thepdvg
volume group contains the important InfoPrint Manager database objects and should be backed up at regular intervals. Thesegvg
volume group contains the segmented print files, and can be considered to be transient data. If you have multiple hard drives available for use withsegvg
, 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
