How to umount when the device is busy

[ZF]

Code:
# umount /media/disk/
umount: /media/disk: device is busy
umount: /media/disk: device is busy


First thing you’ll do will probably be to close down all your terminals and xterms but here’s a better way. You can use the fuser command to find out which process was keeping the device busy:

Code:
# fuser -m /dev/sdc1
/dev/sdc1: 538
# ps auxw|grep 538
