Mount a Windows DFS Namespace in Linux
We have a domain-based DFS namespace that refers to redundant (replicated) file servers shares. With Windows client, failing over are (relatively) transparent. However, we have a CentOS 6.3 box that needs to access the DFS shares, and this is where it becomes problematic.
Initially, CentOS couldn't mount a share under the DFS UNC (ie: \\example.com\dfsNamespace\share). Adding cifs.upcalls in /etc/request-key.conf as such made it mountable: http://mikemstech.blogspot.ca/2012/10/how-to-mount-dfs-share-in-linux.html. But upon further testing, it will only attempts to mount the first referral even if it is down while other referrals available, making the use of DFS moot.
Is it possible to make use of the redundancy feature DFS on CentOS?
Right now, I'm trying to work around the DFS mount problem by using autofs' multi-mount map feature to provide the real file shares to autofs, and hoping it will be able to pick the servers that are available. But I'm not having much luck with multi-mount map for CIFS. Seems like a NFS only feature?
