Our AFS cell has recently expanded into a university wide storage
service. As part of this expansion I need to add some new DB servers
that will have lower ip addresses than the existing DBs.

Would the following work

i) bring up new dbs but do not restart db processes on other DBs so
existing coordinator maintains role (will this work?)

ii) distribute new DB settings to all afs servers and clients (mix of
dns and static clients)

iii) once all clients reconfigured restart db processes to force reelection

Some questions,

i) once I alter all the servers via bos addhost command do I need to
restart the fs/db processes to get the servers to use the new settings?

ii) can the server processes use DNS to get database servers like the
client can?

iii) Is fs newcell sufficient to get linux client to use the new servers
or is a restart safer?
