Device Mapper Resume Ioctl Failed Truecrypt For Mac

Miro8, If you can create a backup of unencrypted data in a safe place then I would do it. As I didn't have all that much data I need to access I used DVDs + USB memory sticks to store backups. I then did a clean install of 12.10 with encrypted /home option, created a new set of TrueCrypt containers and filled them with the unencrypted backups. It all worked with TrueCrypt and Ubuntu working together without problems. You may well be able to manipulate LVM to short cut these steps but I do not have the knowledge to guide you.

You can never have too many working backups. Hope it all goes as expected.

Try to mount a TrueCrypt file Error: device-mapper: resume ioctl on truecrypt8 failed: Invalid argument Command failed.

Hello, @ here is the update, sorry I was busy. I installed ubuntu live stick from installation cd (command was usb-creator-gtk) and boot from it, installed truecrypt - the same version what I use on that disk. What happened is that with the default truecrypt settings I got the same error as specified in the first post, so I couldn't mount it, then I unchecked option in truecrypt settings: settings-preferences-system integration: 'DO NOT USE KERNEL CRYPTOGRAPHIC SERVICES' and I could finally mount and see the data. But from what I've read, without using kernel cryptographic services truecrypt performance will be very slow. So most important is I can backup data now but what to so now?! I thought clean and new installation of ubuntu might solve the problem, knowing I need to uncheck this option probably I will need to look some alternative software. I choosed truecrypt because it's multiplatform software.

Still need help.

You may get an issue with on your synology about the ioctl and the device mapper (dm). Do 'dmesg' when you try and use truecrypt to mount an image and see if it complains about a missing module. The issue is because the synology default kernel lacks the required device mapper crypto module and the crypto modules XTS and LRW. You can compile these using an ubuntu/linux host and the Synology cross-compile tools and sources. See my post on c. Alternatively, if you are on a synology 1511+ or similar (running a x86 processor - do 'uname -a' to check), leave me a comment and i will email you the pre-compiled modules). Anonymous Hi, Since you seem expert in compiling kernel modules for Synology, I have a question for you: I have DS-411+II, which has the same CPU and runs the same kernel as your 1511.

When I ran DSM 3.2 I had no problem using pl2303.ko and usbserial.ko for my prolific USB to Serial adapter. I downloaded the kernel modules from the web.

When I switched to DSM 4.0 they stopped working. DSM 4.0 uses the same kernel as 3.2 (2.6.32-12), so I don't understand why these modules stopped to work (no attachement to /dev/ttyUSB0). I tried to compile the drivers by myself (used x8664. ARCH=x8664, and succeeded in making the ko files however NAS couldn't boot with these drivers.) Can you please compile these drivers for me, or explain to me what has gone wrong? You can mail me at lebovitz at gmail.

Hi Kevin, I actually use the built in Synology encryption. It is using the well known eCryptFs linux software (used by google, ubuntu, etc) so I'm sure of it's reliability.

The best thing about it, which is important to me, is that if the NAS fails, I know I can use a regular linux box to recover data (As long as you have the encryption key. I recommend you take 3 copies of the key on high quality USB locked in safe places + a cloud backup of it.) To be honest I find it a lot faster than truecrypt. When I compiled truecrypt, it was much of a case of get to step X then find solution to problem Y, rinse and repeat until it finally compiled. Then there is further issues of getting the system to mount the volume.

You should be OK with a lot of googling, but I don't feel like it is a long term 'backup' type solution.
