For example, i have two servers AFR'ing each other. I have two clients set up to access the AFR cluster via HA. For reasons of resource distribution, i would like Client01 to prefer to use Server01, and Client02 to prefer to use Server02. currently HA does not provide facility for specifying this option.How does the HA translator choose a node, exactly ? Does it randomly select one from the list of available subvolumes, or does it pick them in the order they're specified in the config file, or some other way entirely ?
Not sure what the default is, but you can specify a preferred read server (writes have to go to all servers regardless) with
"option read-subvolume" in the volume spec. Gordan
