Oh also, I'm not sure why you're adding the new machines to the CellServDB before the new server is up. You could bring up e.g. dbserver #4, and only after you're sure it's up and available, then add it to the client CellServDB. Then remove dbserver #3 from the client CellServDB, and then turn off dbserver #3. You would need to keep the server-side CellServDB accurate on the dbservers in order for them to work, but the client CellServDB files can be missing dbservers. This won't work if a client needs the sync-site, and the sync-site is missing from the CellServDB, but in all other situations, that should work fine. -- Andrew Deason adea...@sinenomine.net _______________________________________________ OpenAFS-info mailing list OpenAFS-info@openafs.org https://lists.openafs.org/mailman/listinfo/openafs-info
