I would like to run the cluster on GlusterFS to have a high-availability and make ‘elastic’ the storage. Do you think that GlusterFS will create issues? Of course each node will use its own space, and not any file will be shared with other databases.
Since I will run on EC2, do you think that using EBS on RAID10 will provide the same solution?
Another idea I have is to use new SSD instances with GlusterFS:
SSD = performance
GlusterFS = distributed FS
