You can find out which process is using the file/filesystem using 'lsof' or 'fuser'. If you don't find any process using it, then try : 'unmount -f -l /data/d1' -f is for forced -l as per the man pages is "Lazy unmount. Detach the filesystem from the filesystem hierarchy now, and cleanup all references to the filesystem as soon as it is not busy anymore. (Requires kernel 2.4.11 or later.)" -f alone will not work. Not sure why it responds twice though. Hope this helps. Namita
