Hi again Mingliang, No, this isn't a bother. Although you found a work-around I thought I'd give you a little more information on the handle ranges.
Although they seem obtuse, they are just 64 bit numbers that assign a given range of handles to a specific server. The ranges must be disjoint. With pvfs2-genconfig it does the math for you, dividing up the handle ranges between all the servers. However, you can assign those yourself if you want to. Typically, I just divide 2^64 by the number of servers (counting both meta and data) and increment the range for each server by that number. Using pvfs2-genconfig is certainly easier but if you get into the case where you want to use sed to modify the configuration know that the only requirements when dealing with handle ranges are: 1) each server you want to perform a given role (data or meta) needs a range assigned to it 2) the ranges must not overlap Michael 2011/4/4 Mingliang Liu <[email protected]> > Hi, > > I fixed it after I searched the keword "noninteractive" in the user > maillist.
