nfs-kernel-server init script calls non-existent /usr/bin/rpcinfo, failure disables NFSv3

[Neil Bertram]

The /etc/init.d/nfs-kernel-server script in Precise has a reference at line 115 to $PREFIX/bin/rpcinfo:

$PREFIX/bin/rpcinfo -u localhost nfs 3 >/dev/null 2>&1 ||
    RPCMOUNTDOPTS="$RPCMOUNTDOPTS --no-nfs-version 3"

Where $PREFIX is /usr, making the path /usr/bin/rpcinfo

Since this command doesn't exist, RPCMOUNTDOPTS always includes --no-nfs-version 3, meaning you can never run with NFSv3 support.

In Precice, the rpcbind package provides the rpcinfo binary, but it's in /usr/sbin/rpcinfo, not /usr/bin/rpcinfo. In Oneiric both rpcbind and libc-bin provided rpcinfo binaries, with the latter being /usr/bin/rpcinfo. It appears libc-bin no longer includes rpcinfo in Precise.

Elsewhere in the same init script (eg. line 88) reference is made to /usr/sbin/rpcinfo as well, so looks like it was just a patchy job updating this init script at some point.

Symlinking /usr/sbin/rpcinfo into /usr/bin/rpcinfo fixed the problem for me, but obviously the init script needs updating.

This is on a complete fresh install of Precise server beta1 with latest packages from the repos.

just to report that i've been hit by the exact same bug. Today I found that$PREFIX/bin/rpcinfo which /etc/init.d/nfs-kernel-server calls does not exist so i fixed it by changing it into $PREFIX/sbin/rpcinfo.

One can verify the fix by doing ps -ledaf | grep rpc.mountd and checking its options. It should not include the option "--no-nfs-version 3"
