"mount.nfs is not installed" is in error

[Jeff Applewhite]

when attempting to start cinder with an NFS volume the following is seen:

Here is the error:

But inspecting…

stack@openstack6:~/$ ls -l /sbin/mount.nfs
-rwsr-xr-x 1 root root 102896 Oct 10 2012 /sbin/mount.nfs

stack@openstack6:~/$ sudo file /sbin/mount.nfs
/sbin/mount.nfs: setuid ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=0x2851d4f8403b34e4e4a19337ecc4309844e39d29, stripped

The error is not accurate. May be a bug in the generic NFS driver related to the fact that mount.nfs while set_up and on real mounts is run as different users.

[Navneet (singn)]

The do_setup for generic driver verifies the mount.nfs but not run as root user whereas the actual mounts are done as root user. This requires the stack user to have admin priviledges or include /sbin in PATH or run the do_setup mount.nfs verify call as root user. I think it would be better to run it as root user as actual mounts are done with admin priviledges.
