It depends on what the replication settings are on a given database. You can utilize PIRC (purge interval replication control) on the databases in the cluster member(s) that are still active to prevent ghost documents from being replicated in when the cluster member that has been down for an extended period of time is brought back online.

Sent by: "Domino400" <domino400-bounces-+hD5IHI5Xscn3HwCXmMcX9BPR1lH4CV8@public.gmane.org> I remember reading somewhere that if a cluster member is down for an extended time, such as a week or so, that bringing it back online can be dangerous. Meaning something like this: ServerA is in a cluster with ServerB. ServerA is dropped for an extended period of time. Databases on ServerB get new records, etc. Since ServerA was down so long if you bring it back up resyncing it may actually drop the new rows or some such thing. It's all a little foggy to me exactly what the concern was. Maybe it was deletions in ServerB would get replicated back in from ServerA. This seems more likely. I tried a google search but apparently I'm not getting the right terminology to find a related hit.
