You would lose the integrity guarantees. If you're talking of data integrity here I doubt that it is there at all. Yesterday I checked a configuration with 2.0.9 replication and 3 clients with iocache. I found out that if I edit an ascii file on one client and save it back being the same size as before, another client still sees the old file content. I checked the servers and found that they all contained the correct new file version. So the data integrity is broken anyway when using iocache on clients . > Gordan -- Regards, Stephan
