Normally I look at ps or top and see what is stuck in D or is using all my CPU. Do you have anything scanning the gluster mount or accessing it in the background? Just mounting on a client shouldn't cause the system to get too much busier, I would think that something is accessing the mount. What is the load when you see when you mount? -b > Thanks, > > Khoi Mai > Union Pacific Railroad > Distributed Engineering & Architecture > Senior Project Engineer > > > > > ** > > > > This email and any attachments may contain information that is confidential > and/or privileged for the sole use of the intended recipient.
