I used this to give a chrooted ftp user access to another area of the filesystem:
mount --bind /var/www/dev/ /home/ftp_user/www_dev
per this website here.
And, oops, I realized I gave the ftp user access to too many files.
How do I fix that? rmdir
doesn't work:
rmdir: failed to remove `www_dev': Device or resource busy
And if it did, I'm afraid it would remove the mounted files.
Best Answer
try
umount -l /home/ftp_user/www_dev
.this will detach the file system immediately, and clean up any leftover references when it's no longer busy.
