Cool, here's the final tested version then:
location / {
try_files $uri $uri/ =404;
index index.html index.htm;
}
location ~ \.php$ {
try_files $uri $uri/ =404;
rewrite_by_lua '
local s = 0; local v = 0;
local source_fname = ngx.var.document_root .. "/maintenance_mode.html";
local file = io.open(source_fname);
if file then v=1; file:close(); end;
if string.find(ngx.var.remote_addr, "^10.10.30.") then v=0; end;
if v>0 then return ngx.exit(503); end;
';
index index.html index.htm index.php;
fastcgi_ignore_client_abort on;
fastcgi_pass myLoadBalancer;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}

This "if" thing is equivalent to the following
rewrite_by_lua '
local v = ngx.var.mmode
if v and v ~= "" and v ~= "0" then
return ngx.exit(503)
end
';
And for your use case you can
1. merge the Lua code in set_by_lua into this rewrite_by_lua, and
2. eliminate the $mmode nginx variable altogether by your own Lua
variable (or even nothing).
