Hi List, We have 2 geographically distant sites located approximately 35km apart with dark fiber connectivity available between them. Mail01 and SAN1 is placed at site A while Mail02 and SAN2 is at site B. Our requirement is to have the mail servers in a cluster configuration in an active/active mode. To cater for the loss of connectivity or losing a SAN itself, I have come up with the following design. 1) Export 1 block device from each SAN to its mail server i.e. SAN1 exports to Mail01 2) Use DRBD to configure a block device comprising of the 2 SAN volumes and use it as a physical volume in clvm. 3) Create a GFS logical volume from this PV that can be used by both servers. I am wondering if this is a correct design as theoretically it looks to address both node and SAN failure or connectivity loss.
