But when > it comes to an Active-Active setup, it seems there are a few problems. Yes. Even active-passive failover is problematic right now, mainly because the method we use for storing reboot recovery information (analagous to the state recorded by statd) is still in flux. We're aware of these problems and working on solving them. There are some rough (possibly out of date notes) here: http://wiki.linux-nfs.org/index.php/Cluster_Coherent_NFS_design but those are more of interest to someone working on design of a solution than to someone trying to set up and use any of this (which we don't recommend doing yet). --b. ------------------------------------------------------------------------- Take Surveys.
