I would try to match similar speed drives in replicated pairs. When you create the volume do something like: gluster v create testvol transport tcp replica 2 node1:/fast node2:/fast node3:/slow node4:/slow I can't think of anything functionally that would cause a problem, you would only write as fast as your slowest brick in the pair though. I see something similar when a disk in my RAID goes bad and starts running in degraded mode. Things work you are just limited to the speed of the slowest brick in the replicated pair. -b > Thanks in advance. > > _______________________________________________ > Gluster-users mailing list > [email protected] > http://www.gluster.org/mailman/listinfo/gluster-users _______________________________________________ Gluster-users mailing list [email protected] http://www.gluster.org/mailman/listinfo/gluster-users
