Question

Mount checking

Asked by: MarkDozier

i would like to know if it is possible to run a script that will check to see if a device is mounted and if  that device is not detected removed the device listing from the machine.
For example - I put a flash drive in the machine. It mounts. I do my stuff and pull the flash drive out.
After some amount of time the drive is still listed when I look in filesystem.
Can this be done without adversly affecting the machine?

You should always unmount the drive before you yank it out.  You will eventually lose data doing it this way.

Er, not really.

You could grep var log messages for errors when you rip the usb out?

Also linux typically doesn't like to umount a drive that is not there?

If you are going to be removing drive without umounting then make sure the fstab entry is set to sync. Async will result in data loss...
