Mounting and unmounting in Linux...

Yo!

Mounting and unmounting in Linux...please advice.

1. I the device is busy and you therefore cannot umount how to find out that what process makes it busy?

2. When you know that which process makes your device busy, how to kill that process.

3. Is there power command which umounts as effectively like it does when Linux closes and reboots...

Thanks!

if the device is busy it is possible that you are in the mounted dir

i.e if you mount your cdrom to /mnt/cdrom and your in that dir when you try to unmount it you will get the device is busy error

being "in that dir" i mean within that tree in a shell, have a file manager open to that dir etc etc.

ps -eaux |grep "mount point" will tell you what is accessing that dir

not that i'm aware of - anyone else?

Yes but changing dir does not allways help.

ie ps -eaux |grep "/dev/cdrom/" will tell you which programs are currently using the mounted CD-rom, for example. See if this resupts in anything. If you can't end the program once you know what it is, you can always do a "kill [PID]" command
