Idmapd refuses to start

[Quentin Godfroy]

Hi,

on a linux 2.6.22.6 acting as client, with nfs-utils 1:1.1.1, the idmapd
daemon refuses to start even if nfsv4 client is compiled in the kernel, the
exact same idmapd.conf works on the serevr box, and of course 
/var/lib/nfs/rpc_pipefs is mounted according to /proc/mounts.

The error reported in the syslog is :

rpc.idmapd[2011]: main: fcntl(/var/lib/nfs/rpc_pipefs/nfs): Invalid argument

a strace indicates that the offending fnctl should be

open("/var/lib/nfs/rpc_pipefs/nfs", O_RDONLY) = 7
fcntl64(7, F_SETSIG, 0xa)               = 0
fcntl64(7, 0x402 /* F_??? */, 0x8000000e) = -1 EINVAL (Invalid argument)


Here is an exerpt from the relevant parts (I suppose) of the kernel config

#
