Well the idea is to build a dual server cluster in a box using hardware
meant more for Windows storage server 2012. This way we do not need to
replicate data across the nodes since the 2 servers see the same block
storage and you have active failover on all the hardware. Dataon has a
system for this and they even suggest using gluster however, I cannot
seem to figure out how to implement this model. All gluster nodes would
need to be active and there doesn't seem to be a master - slave failover
model. Thoughts?
One way of doing this could be:
- Both servers have to be part of the gluster trusted storage pool.
- Create a distributed volume with a brick from one of the servers, say
server1.
- Upon server failover, replace/failover the brick by bringing in a new
brick from server2. Both old and new bricks would need to refer to the
same underlying block storage. I am not aware of what hooks Syncro
provides to perform this failover. Brick replacement without any data
migration can be achieved by:
volume replace-brick <volname> <src-brick> <dst-brick> commit force
