Following the above hint from Peter Bell, I've now added the proto and vers options to the amd.home-map (beside that, I set the rsize and wsize to 16k). Demanded are the following options:
~$ ypcat -k amd.home | grep 'default ' /defaults type:=nfs;sublink=${key};opts:=rw,grpid,hard,intr,nodevs,nosuid,vers=3,proto=tcp,rsize=16384,wsize=16384;rfs:=${autodir}/${rhost}/fs1/home;fs:=${autodir}/${rhost}/fs1/home The result is: ~$ cat /proc/mounts | grep nfs | grep home seth:(pid1512,port1022)/ /home nfs rw,relatime,vers=2,rsize=1024,wsize=1024,namlen=255,acregmin=0,acregmax=0,acdirmin=0,acdirmax=0,hard,proto=udp,port=65535,timeo=7,retrans=3,sec=sys,local_lock=none,addr=127.0.0.1 0 0 amun:/net/amun/fs1/home/ /net/amun/fs1/home nfs rw,nosuid,relatime,vers=2,rsize=8192,wsize=8192,namlen=255,acregmin=0,acregmax=0,acdirmin=0,acdirmax=0,hard,proto=udp,port=65535,timeo=7,retrans=3,sec=sys,local_lock=none,addr=172.20.91.20 0 0 The amd registers in the mount tab with vers=2,proto=udp,rsize=1024,wsize=1024, while the mount itself is mounted with vers=2,proto=udp, rsize=8192,wsize=8192. The given workaround does not work for me, and I also don't have a clue why the 16k read/write size is also not used. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/680680 Title: mount picks the wrong version of NFS filesystem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nfs-utils/+bug/680680/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
