[ovirt-users] Storage question: single node gluster?

Hi There, This is not strictly oVirt, but is storage-related, so hopefully you will indulge me? Is there any detriment (performance or otherwise) in setting up a single-node glusterFS storage? I know glusterFS is designed to be used with multiple nodes, but I am wondering if there are any ill-effects in configuring current storage as a single-node cluster, with the idea of possibly adding future nodes in the future? Thanks! :-) -Alan
