three new servers running redhat linux. What we'd like to know is whether
we can take down the old servers, and renumber and rename the new servers
to match the three old servers so that we do not have to touch the
CellServDB entries in all of the clients. We do have DNS set up for our AFS cell, but many clients are still using CellServDB files.
The current servers are:
cs.unc.edu # University of North Carolina at Chapel Hill
152.2.128.1 #crow.cs.unc.edu 152.2.128.2 #falcon.cs.unc.edu 152.2.128.8 #thrush.cs.unc.edu
What we'd like to do is take down these servers, and then change the ip names and numbers on the new servers to match these, with as little fuss as possible for our clients.
Obviously, our main concerns are data integrity and maintaining uptime. We've found some references in the list archives about changing server numbers, eg: <http://www.mail-archive.com/[email protected]/msg14132.html> <http://www.mail-archive.com/[email protected]/msg05825.html> <http://www.openafs.org/pages/doc/AdminGuide/auagd008.htm#Header_160>
But so far what we've found online assumes that an existing server is changing to a new unused number, not that a new server is assuming the ip identity of a different server.
So the basic questions are:
Is it possible to safely renumber the servers in this way?
If it is possible, would we need to quarantine the servers for some period of time on the network (so that active connections on clients would time out or the servers could more safely restart the cell)?
Since ip ordering is important to AFS, is there a particular order we should use if we can do this at all?
And has anyone out there done this before, and if so, can they give us any advice? (esp. advice to the effect of "please please don't do this".
Thanks in advance for any help, bil
