Another solution I come across is Glusterfs for high availability storage.. But I'm not quite sure if Glusterfs will automatically increase the storage capacity of server A by adding the storage space available in server B. That way if server A is full, Glusterfs will send the load to the server with available space...
Yes, this is what I was talking about. This would allow you to expand your storage by pooling it. AUFS provides the same concept and runs in kernel space, so it is faster than the FUSE based mhddfs. Ceph or Gluster will likely be a bit of overkill at this point
