We're using storage spaces direct as a disk target for backup storage. Our backup product has a direct SAN attached method for backup of VMware virtual machines versus using a proxy that uses HotAdd to send the data over the network. This is where the Windows OS has block level access to the storage but doesn't need to mount it. My intent was do to this with HBAs in the physical machines hosting the storage spaces direct volumes.
The requirements for the direct SAN attached storage are to disable the automount feature in Windows. There's a variety of ways to do this, I would use DISKPART commands:
DISKPART> AUTOMOUNT DISABLE
What I can't find is any documentation anywhere if this is a supported configuration to disable automount in a storage spaces direct cluster. The only thing I know for sure is that the storage spaces direct cluster as setup currently has this feature enabled.
I think it would be OK to disable it since the volumes are controlled by the cluster service and I'm fairly certain that handles the mounting of volumes for CSV and any other virtual disks directly associated with roles controlled by the cluster.
I'm also not sure this forum is the correct one for storage spaces direct questions, and I'd appreciate a point in the right direction on where to post if it isn't.
