Verify That the Hard Disk Did Not Mount

Action

To verify that the hard disk (ad1) did not get mounted, use the following CLI command:

user@host> show system storage 

Sample Output

The following sample output was taken from a RE-333 Routing Engine.

user@host> show system storage

What It Means

The command shows that the hard disk (ad1) is not mounted. Instead, /var now exists only in the swap partition (mfs:139), so any contents saved to /var will not be saved at the next reboot.

What It Means

The example shows that var has a symbolic link to the /tmp/var directory. It resides under the /tmp/var directory, and is mounted on the mfs partition.
