Hi Everyone, First of all a big kudos to CODA community, it's a wonderful job you guys are doing. In one of the documents I read that CODA uses read-one, write-all approach for server replication. I am a little bit concerned here. Let's assume that there are three replicated servers A, B and C. And let's assume that client Ac is connected to A, client Bc is connected to B and client Cc is connected to C. In this scenario let's say there is a file named "CommonFile" under root directory of CODA share. Consider a sequence of following operations on this file Ac opens "CommonFile" for write Bc opens "CommonFile" for write In this situation there is a chance for Basically I would like to know whether there is any locking done when accessing a single file, if yes who is responsible for it. Or is it a limitation that files cannot be used simultaneously at two clients connected to two different duplicated servers. Please feel free to clarify anything in this question with me; I may have not stated things clearly. Thanks in advance. Cheers, ArunReceived on 2004-05-18 12:31:34
