Hazarding a guess, but there is only one SSD NSD, so if all the metadata
is going to go on SSD there is no point in replicating. It would also
explain why it would believe it can't maintain the metadata replication
factor. Though it could just be a simple metadata size is larger than
the available SSD size.
