We want to change the service node of an OST.  We think this involves:
1. umount the OST
2. tunefs.lustre --erase-param failover.node --servicenode= at o2ib, at tcp pool1/ost1

Is this all?  Unclear from the documentation whether a writeconf is 
required (if it is, then we'd need to dismount the whole file system, and 
take it all down, and writeconf every ost/mdt/mgt and then mount them in
