Meaning The command output displays statistics about the amount of free disk space in the

router’s file systems, including the amount used, the amount available, and the percentage

of system space being used. The values are displayed in 1024-byte (1KB) blocks.

Filesystem is the name of the file system on which the Routing Engine booted. The

command output also displays the directory to which the file system is mounted. During

normal operation, the / and /config directories are from the CompactFlash card and the

/var directory is from the hard drive. If the router booted off the hard drive, the show

system storage command will show all three directories on the hard drive. If the hard

drive fails and the router booted off the CompactFlash card, the show system storage

command will show all three directories on the CompactFlash card.
