Patent ID: 7694166

Claim:
A method in a clustered storage server system, comprising: detecting a failure in a first storage server having a first control-of-service policy to control a first storage system, wherein the first control-of-service policy includes a first plurality of scheduling rules to prioritize file system access requests within the first storage server during normal operation of the first storage server; and executing a cluster takeover procedure in a second storage server having a second control-of-service policy to control a second storage system, wherein the second control-of-service policy includes a second plurality of scheduling rules to prioritize file system access requests within the second storage server during normal operation of the second storage server, the cluster takeover procedure comprising: taking control of the first storage system with the second storage server; and merging the first control-of-service policy with the second control-of-service policy in the second storage server to create a merged control-of-service policy in the second storage server to control the first storage system and the second storage system.
