This post is more for a reminder to myself. I am always forgetting where I need to mount the transfer LUN on vCloud Director cells.
The transfer LUN is used for uploading and downloading, and can be NFS or other types of shared storage. It is only used for when you have more than one vCD cell.
The location is /opt/vmware/vcloud-director/data/transfer
If anyone is interested in reading more about what the transfer mount is used for Jason Boche wrote a great article on it.
