Did you look for the mount protocol when getting a network trace (filter "rpc" in wireshark). Could you: 1) run "rpcdebug -m nfs -s mount" before mounting, post output of dmesg after mount fails. 2) add -v to the mount command and post the output 3) maybe get rid of srcaddr= option / post info about the ip configuration -dros > > > I am curious if anyone else has seen errors similar to this? > > > Thanks, > Ben > > -- > Ben Greear <greearb@xxxxxxxxxxxxxxx> > Candela Technologies Inc http://www.candelatech.com > > -- > To unsubscribe from this list: send the line "unsubscribe linux-nfs" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
