Hi Javier, nfs.v4.read_delegation on (value might be overwritten in takeover)
nfs.v4.write_delegation off (value might be overwritten in takeover) Did you try disabling nfs.v4.read_delegation? No, since we only recently changed from NFSv3 to NFSv4 and with v3 were using mount option nocto on 99% of the mounts for performance. We have currently no idea what implications we would have if we turn off read delegation. Is there any way to estimate/measure the performance improvements achieved by using read delegation as in our current setup? >From looking through the source the message seems to be just a warning, right? Thanks Rainer
