Solaris Common Messages and Troubleshooting Guide

umount: warning: /string not in mnttab


This message occurs when the superuser attempts to unmount a file system that is not mounted. Subdirectories of file systems, such as /var, cannot be unmounted.


Run the mount(1M) or df(1M) command to see which file systems are mounted. If you really want to unmount one of them, specify the existing mount point.
