Can I use DFS Replication with Shared Storage?

  • 772

I am looking to add redundancy to our DFS shares and want to utilize a new iSCSI SAN array in the process. I am thinking of having two servers (one virtual, one physical - sitting on different hosts) connected to a common SAN LUN, both providing DFS access.

If I am not mistaken, DFS was created to facilitate replication between two different storage arrays but share a common name space, so will DFS work in the scenario above since in theory it would be trying to replicate to a shared common storage array? What would be some alternatives?

    No. With the exception of Hyper-V CFS etups, NTFS can NOT HANDLE MORE THAN ONE COMPUTER ACCESSING A DISC. It is not a cluster capable file system.

    If you have 2 servers connecting to one lun EACH, it will work (löike if they have local discs).

    If the access the same disc, they will show file system corruption.

    Not a DFS issue - an NTFS issue.
