Windows 2008 R2 File Server Cluster vs. DFS


We're currently using 2 Windows 2008 R2 with DFS but discovered some issues with:

  • replication of permissions (permissions are not replicated across DFS members)
  • replication of quota (quota is disk-based)

Do these problems exist in clusters? Meaning, if we set the permission/quota on a folder in a member cluster, will all members of that cluster inherit the permission/quota? We will have a dedicated servers (HP P4300 Lefthand) and we plan to use it for the file servers as well. So, our choices are: DFS or fail-over cluster.

Best Answer anaswers your question on quota behaviour on cluster nodes. Note this is for FSRM quotas. FSRM and NTFS quotas are apparently different. See Which do you have? Also see

Without wanting to sound like marketing I'd like to say DFS and clustering are complementary technologies. Clustering is for those that want quick recovery from server (node) failure. DFSR is for keeping multiple copies in several places in sync. This is why DFSR is supported on clusters starting with 2008 R2. See .

What are the issues you have with replicating permissions? Did you pre-seed content in supported ways before creating RG/RF? I wonder if a robocopy usage issue is the cause fo your permissions issue. See
