No. There is a potential problem with locking across NFS, but it has never been reported as actually occurring in practice and, if it did, it would just result in a denial of service, not repository corruption. > 2) Asked another way, if we have just one server > dedicated to cvs and it is the ONLY mount to the > repository that exists, are we ok or still at > risk? Still at risk. The problem is not with multiple NFS clients, but with interoperability between different NFS client and server implementations. If you use the same NFS implementation for both the client and server system, you will almost certainly not have any problems. Similarly, if your NFS server is a system that's specifically marketed as a file server and has been tested with a wide variety of clients, you are unlikely to have any problems. You are most likely to have problems when you use a general-purpose system as a server and have very different NFS implementations on the client and server (e.g., one is a commercial Unix system and the other is a Linux system). > 3) If we are still at risk, then I assume that to > avoid using NFS mounting, our repository must > exist on the same server CVS is set up on?

You're just trading one risk for another. Sure, if your CVS server machine dies you can mount the disk on another machine, but what are you going to do if your NFS server machine dies? Is your CVS server really that much less reliable than your NFS server? -Larry Jones Like I'm going to get any sleep NOW. -- Calvin _______________________________________________ Info-cvs mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/info-cvs
