Like many HA implementations, it is not fault tolerant, when something fails, the client tends to know it. The applications here are not well behavied in those cases. > It helps to know what you are sharing - i.e., if someone tells me that they > have this product that uses Btrieve databases as its underlying mechanism > (and yes, I have to work with a product that does exactly this ;-), I would > say 'run away from NFS immediately' - the getattrs calls will kill your app. > Other file sharing mechanisms have different profiles and issues. Mostly large and small text files. Generally not accessed by more than one client at a time. Performance is not a big issue. Total storage is in the TB or 10s of TB range.
