Hi, I'm doing a NFS HA setup for KVM and need lock reclaim to work. I've been doing a lot of testing and reading in the past week and finally figured out that for reclaims to work on a 4.1 mount (4.1 is preferable due to RECLAIM_COMPLETE and thus faster failover), the server hostnames need to be the same. RFC specifies that reclaim can succeed if server scope is the same and in fact, the client will not even attempt a reclaim if the server scope does not match. But...there doesn't seem to be any way of setting server scope other than changing server hostname? RFC states: "The purpose of the server scope is to allow a group of servers to indicate to clients that a set of servers sharing the same server scope value has arranged to use compatible values of otherwise opaque identifiers." The nfsdcltrack directory is properly handed over during failover so I'd need some way of configuring server scope on this "set of servers"? From the code, the server scope is simply set to utsname()->nodename in nfs4xdr.c. What am I missing here, how can this work when Heartbeat needs different names for nodes?
