Unix, Xenix and ODT General FAQ

Why can't I unmount my CDROM?

Filesystems not unmounting: probably because some process is using it. It might even be you- if you have CD'd there. Something that sometimes catches folks: you "cd /cdrom" and then perhaps start "ksh". Later on you cd somewhere else, but the shell you started with is still sitting on /cdrom- and it wll not unmount.

Use "fuser /mnt" or "fuser /dev/cd0" (note that on Linux these will produce different results but re equivalent on OSR5 at least) to find the process and kill it.
