Disk Space Management for Junos OS Installation

 

A Junos OS 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 OS:

    • On the M Series, MX Series, and T Series routers, the unlink option removes the software package after a successful upgrade.

  • Download the software packages you need from the Juniper Networks Support Web site at https://www.juniper.net/support/. The download program provides intelligent disk space management to enable installation.
