I can't mount my encrypted devices anymore.
The error is:
device mapper: create ioctl failed device or resource busy
This error arises both with two different programs to access TrueCrypt encrypted devices: TrueCrypt and Tc-play.
In this case, the recommendation is to remove
/dev/mapper/truecrypt* directories, or look for processes that are blocking the device. However, there is no
/dev/mapper/truecrypt* directory, and
lsof returns nothing.
One TrueCrypt device takes a whole HDD. According to
fdisk, this partition is formatted with HPFS/NTFS.
Another TrueCrypt device is on a partition on
/dev/sda. According to
fdisk, this partition is "Linux" (ext3 or ext4, if I remember correctly).
What could be causing the error?
