Cannot unmount a devicefile system

[Ameena Shaik]

Hi,

I have a problem while checking the bdf output on an unix system.

bdf

In the above output the /dev/deviceFileSystem is showing 100%. Also I cannot umount the filesystem. Can u please help me in resolving this issue.

Hi Ahsan,

While unmounting I am getting an error message as follows

umount: cannot access DevFS-specific umount command
umount: return error 1.

#devfs stop
