I tried and got stuck on this:

 # bpsh 0 rpc.mountd --no-nfs-version 3
 svc_tcp.c - cannot getsockname or listen: Invalid argument
 mountd: cannot create tcp service.

** Any explanation is more than welcome. **


Related (I hope) source code can be seen here:

For the rest, NFS server on scyld node seemes possible. So far I
managed to start these (more or less related) parts:

# bpsh 0 rpcinfo -p
   program vers proto   port
    100000    2   tcp    111  portmapper
    100000    2   udp    111  portmapper
    100024    1   udp    806  status
    100024    1   tcp    808  status
    100021    1   udp   1025  nlockmgr
    100021    3   udp   1025  nlockmgr
    100011    1   udp    943  rquotad
    100011    2   udp    943  rquotad
    100003    2   udp   2049  nfs

The rpc.mountd problem might be related to resolver/names oddities,
e.g. netstat says:

 # bpsh 0 netstat          
 Active Internet connections (w/o servers)
 Proto Recv-Q Send-Q Local Address           Foreign Address         State

 tcp        0      0 .0:1591                 .-1:1936                ESTABLISHED 
 tcp        0      0 .0:1590                 .-1:1936                ESTABLISHED 
 tcp        0      0 .0:1589                 .-1:1937                CLOSE       
 tcp        1      0 .0:1432                 .-1:1852                CLOSE_WAIT  
 ...
 tcp        0      0 .0:615                  .-1:2223                ESTABLISHED 
 Active UNIX domain sockets (w/o servers)
 Proto RefCnt Flags       Type       State         I-Node Path


This certainly does not look as usual and mountd might get confused.

Thanks for any comments
