Exchange DB mount of quorum fails

lets say if i have 2 exchange 2010 mailbox server in a DAG and a 2 HUB and a CAS. File share runs on HUB1 for teh DAG and what if i lose one of the mailbox server and HUB1 server running file share witness? The database will be unmounted and wont be mounted back until i have quorum. What is the alternative? can i change the DAG to use another server as FSW?
This is not working for me in my test lab!
Any help will be appreciated

You can configure an additional witness server for the DAG itself.

Node and Disk Majority (recommended for clusters with an even number of nodes)

Can sustain failures of half the nodes (rounding up) if the disk witness remains online. For example, a six node cluster in which the disk witness is online could sustain three node failures.

Can sustain failures of half the nodes (rounding up) minus one if the disk witness goes offline or fails. For example, a six node cluster with a failed disk witness could sustain two (3-1=2) node failures.

Not enough nodes to sustain the witness failure.

The alternate file share witness is not a redundant, automatic file share witness backup. Its simply a defined file share witness used during a datacenter switchover.

If you have lost quorum, you will need to seize it in DataCenter B or bring up DataCenter A .

Each side of the dag is a "datacenter" per se. Just bring up the one side.
