Solaris Common Messages and Troubleshooting Guide

nfs umount: string: is busy


This message appears when the superuser attempts to unmount an active NFS file system. The busy point is the working directory of a process.


Determine which shell (or process) on the workstation is currently located in the remotely mounted file system, and change--cd(1)--out of that directory. Be wary of subshells (such as su(1M) shells) that could be in different directories while the parent shells remain in the NFS file system.
