I changed volume-id to glusterd-uuid to shut up a warning.

After a few tests, I am now conviced the protocol error is a consequence
of an earlier bug. On a fresh volume that contains nothing, ls -l on an
unexisting file at volume root causes a crash in lookup code.

[posix.c:129:posix_lookup] 0-foo-posix: null gfid for path /x
[posix.c:154:posix_lookup] 0-foo-posix: lstat on (null) failed:
Undefined error: 0

This is where it comes from: 

#define MAKE_INODE_HANDLE(rpath, this, loc, iatt_p) do { \
        if (uuid_is_null (loc->gfid)) { \
                gf_log (this->name, GF_LOG_ERROR, \
                        "null gfid for path %s", loc->path); \
                break; \
        } \

Is it something sane?
