Hello
I am a relatively Newbe to Tiny Core Linux and I have been having trouble dismounting an encrypted container file created with Truecrypt.
Dismounting from the truecrypt gui fails with this error report: “Device-mapper: remove ioctl failed: Device or resource busy. Command failed”
I then try to dismount manually; first, by identifying the associated loop with “losetup -a | grep /home/tc/container” (where “container” is my encrypted container file) and then by entering “umount /dev/loopX”
The output of the umount command is: “umount: /dev/loopX is not mounted (according to mtab)”. When I go to the truecrypt gui and try again to dismount via the dismount button, I get the same device-mapper error message.
Some times (rarely) “umount /dev/loopX does not give any message and when I go to the truecrypt gui and hit “Dismount" button the device-mapper error message is not displayed and the the encrypted container file is dismounted properly.
Can anyone give me some suggestions what to try to get a proper dismount from the truecrypt gui? I can dismount by rebooting the tiny core but this is not very satisfactory.
Truecrypt.tcz was installed along with Nautilus.tcz, cryptsetup.tcz and util-linux.tcz.
Thank you in advance for any help
