[lustre-discuss] Changing OST servicenode

[Alastair Basden]

Hi,

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=172.18.100.1 at o2ib,172.17.100.1 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 
order).

Thanks,
Alastair.
