Depending on what you're trying to do by having this filesystem available on two hosts at the same time it may or may not be possible.
At the heart of your issue is that NTFS is not a clustered filesystem. This means that it does NOT support being mounted simultaneously on two hosts.
- If you look at MSCS / Failover clustering you can support a service where the filesystem is active on one host and can fail over to the other host.
- If you need to have simultaneous read/write access to a common filesystem, in a pure Windows way, you should be looking at SMB (aka CIFS) shares not LUNS or you should be looking at 3rd party cluster filesystems.
- Depending on your windows version you may have other Microsoft solutions (2012 has some interesting fileserver capabilities that leverage SMB3.0)
- You can also, with Win2008 +, mount a volume via NFS (from the command line) and have it available on both hosts simultaneously.
If you want specific suggestions, share some background on what you want to achieve.
