Renaming a file on Debian Wheezy does not work using fs.rename or fs.renameSync.

This only happens in files moved from /tmp/ to another location.

The reported error is: EXDEV, cross-device link not permitted.

This is another solution that works for me:

var fs = require("fs"),
util = require('util');
...
//fs.renameSync(files.upload.path, "/tmp/test.png");

var readStream = fs.createReadStream(files.upload.path)
var writeStream = fs.createWriteStream("/tmp/test.png");

util.pump(readStream, writeStream, function() {
    fs.unlinkSync(files.upload.path);
});

Debian Wheezy uses tmpfs for the /tmp folder by default.

This can be turned off by modifing /etc/default/rcS.

RAMTMP=yes

has to be set to 

RAMTMP=no

    The problem is that Node fs.renameSync cannot do cross-device renames, not that some particular machine has tmp on different device. Don't turn off RAMTMP just because this. (Also on current Debian Jessie RAMTMP doesn't work, /tmp tmpfs is configured via systemd.) Use some smarter rename, for example the module __mv__: http://stackoverflow.com/a/29287813/196206 – Messa Aug 18 '15 at 11:38
