Hi, i am running FC4 latest patches and latest kernel. i have a crypted partiton using cryptsetupLuks. mounting the device with cryptsetup luksopen /dev/hda4 crytpodev mount /dev/mapper/cryptodev /space works fine. accessing and working with the partiton and files on it works perfectly BUT when i try to unmount this parttition using: umount /space crytpsetup luksclose cryptodev i always get and error saying: 'Device is busy'. i am not located on the device, fuser doesn't show any process accesing the device and umount -f also fails with the error message. any ideas what i am doing wrong ? any help appreciated. regrads, Mattthias _______________________________________________________________ SMS schreiben mit WEB.DE FreeMail - einfach, schnell und kostenguenstig.
