Subject: [Gluster-users] Stripe Volume- File Location Decision
as it looks like as distributed volume on a cluster with a slow line slows down all writes I have to look for a different approach.
Let's say we create a striped volume within a cluster of two hosts. The hosts are located on two different sites (connected with a slow 10Mbit line).
I am aware in case one node fails the files stored on this host are not accessible as long as the host is down.
What I am insterested in is how a file is placed in case of a write. I will have clients on two IP subnets accessing the two hosts (which are each in the same subnet).
A client in subnet A is connected to host A and creates a file- is this placed on host A or might it happen it is stored on host B 8which means is goes through the 10Mb line)?
Thanks for ideas.
