Are you or someone else cd into that filesystem?
Otherwise you would need to use fuser(1m) or lsof to find out who. See some of the following links:

did u try to unmount in cdrom mount point?

if not

is anything run from your CDROM?

Do you have any external disk?

[F Verschuren]

cd /
fuser -c /cdrom
ps -ef |grep numbre to see what is running on the cd.
than kill (-9) the stuff running on the cd.
than the cd can be unmounted.

ps there are differend kind of mounts if you post bdf /cdrom (if the previus din't work) we can maybe help somemore...

hi,


device busy is a massage declares that device is in use by another process. to unmount the cdrom device you need to close/kill all the processess which are accessing cdrom files.

please try:

cd OUT of mount point of cdrom

fuser -ku

umount

if still you don't can umount please, check that in you don't have any filesystem mounted
