I have a Linux server currently running under a Microsoft Virtual Machine. I have it set up so that the storage drive is set up as a secondary virtual disk. I need to move this machine to a new box running LXC, but storage is tight. I'd like to use my NAS for the storage drive, but it is currently formatted as NTFS for a number of other applications in my environment, so I can't link a folder to the NAS and keep the necessary permissions to run my Linux-based application.
I've thought about using TrueCrypt to create a virtual drive that is stored on the NAS, then mounting that under my Linux VM. Would this be a valid method to use, or am I asking for trouble.
Also, would using a loop device stored on the NAS be a better option?
Recommendations are very welcome.
