Thanks a lot for replying to my question. Actually I have to distribute data on my web servers as we are using a provisioning software and it just uses this architecture. My plan is to setup 2 active servers that do not share any data , and one passive server which is for both of them. Node A ,C (cluster service 1) Node B , C (cluster service 2) Node c : (Failover domain 1 : service 1,failover domain2: service 2) I want to setup GFS between A,C and another pair B,C My main question is whether I should use GFS or not ? I am confused about whether I should use GFS when I am using High availability service management from Cluster suite. --Regards.
