Hi folks,

I have below code for unmounting, but i need validation filesystem is unmounted or not, if not it give us error. Please confirm below code or need modification. Please suggest.

Code:

You might want to use fuser -ck /mountpoint before executing umount.

That way fuser will kill the pids which are potentially holding the mountpoint and umount will work fine.

As for mounting, you can use return code ($?) to verify the mount is successful (should return zero if mount is success).
