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 J Series routers, 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 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, 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.
