Managing Available Disk Space

A software installation or upgrade may fail if your router has a shortage of disk space. If a disk space error occurs, use one or more of the following options to complete the installation:

• Use the request system storage cleanup command to delete unnecessary files and increase storage space on the router.
• Specify the unlink option when you use the request system software add command to install the JUNOS software:
  • On the J-series platform, the unlink option removes the software package at the earliest opportunity to create enough disk space for the installation to finish.
  • On the M-series, MX-series, and T-series platforms, the unlink option removes the software package after a successful upgrade.
• Download the software packages you need from the Juniper Networks Support Web site, http://www.juniper.net/support/. The download program provides intelligent disk space management to enable installation.

  Note: If you are upgrading the J-series router from a remote location, the installation program automatically checks for enough disk space for the process to finish.

For more information on the request system storage cleanup command and the request system software add command, see the JUNOS System Basics and Services Command Reference.
