So my 4 questions: WHY is the drive locked? And HOW to work arround it other than to reboot the system? Can't a forced umount be implemented for other cases than just for NFS (as manpage sais)? Or is my system just too old and buggy? (because it is, besides from updates) And yes: It's more than once this happened: # umount /mnt/toaster umount: /mnt/toaster: device is busy # fuser -v -m /mnt/toaster/ # mount | grep toaster /dev/scd0 on /mnt/toaster type iso9660 (ro,noexec,...) # lsof | grep -e scd0 -e toaster # umount /mnt/toaster umount: /mnt/toaster: device is busy # umount -f /mnt/toaster umount2: Device or resource busy umount: /dev/scd0: not mounted umount: /mnt/toaster: Illegal seek # umount /dev/scd0 || umount -f /dev/scd0 umount: /mnt/toaster: device is busy umount2: Device or resource busy umount: /dev/scd0: not mounted umount: /mnt/toaster: Illegal seek # umount -V umount: mount-2.10m # fuser -V fuser from psmisc version 18 # -- Greetings, Jim -- Gruss, Jim
