  2. Partition disks. Select Manual.

Please note:

  1. The use of separate partitions for the /home and /var folders greatly facilitates disaster recovery and system stability.
  2. Using the /home partition for DSpace system and data files is generally accepted Unix/Linux systems administration best practice.
  3. And one NEVER installs operational software in a top level folder on a Unix/Linux server.

The following partition scheme is recommended.

/

ROOT partition, where all the system software is installed

10GB Minimum - 20GB preferred

n/a

SWAP partition

2x installed RAM

/var

VAR partition, where all the log files and database files are installed

10GB Minimum - 50GB preferred. This depends on how big your database index files get and how large the log files.

/home

HOME partition, where all the DSpace software files and bitstreams are stored

All the rest of the total disk capacity.

Example Setup for SUNScholar

  • /dev/sda1 = / - is the root/system partition.
  • /dev/sda2 = is the swap partition and is not listed.
  • /dev/sda3 = /var - is the partition where the database and log files are stored.
  • /dev/sda4 = /home - is the partition where the DSpace application and assetstore are located.
