J Series Considerations
Currently, J Series routers—the chassis most commonly used in the enterprise—are not equipped with a rotating media hard drive. Their on-system memory for storing JUNOS images is limited. As a result, some additional image upgrade commands and options are available as mentioned previously.
Cleanup
J Series chassis support a cleanup command that
frees up storage space by deleting files in the /cf/var/tmp/ directory that have not been
accessed in the past 48 hours, as well as all crash files in the
/cf/var/crash directory. This
command also rotates all current logfiles in the /cf/var/log directory. This command takes a
minute or two to complete. You can run it immediately before a software
upgrade to free up space for the JUNOS image:
