Dear WinDRBD users,

WinDRBD release 1.1.7 is out, the main new features are:

.) A blue screen that might trigger when memory allocation fail at
    a specific code path was fixed.

.) A performance bug introduced in WinDRBD 1.0.0-rc11 was fixed.
    Reason was that the TCP/IP nodelay option was not set which causes
    TCP/IP data stream sends being delayed by 20ms. Therefore performance
    with single threaded synchronious I/O was bad.

.) Some changes to make future releases of DRBD reactor for Windows

If you are affected by the blue screen an update to this version is highly

You can download an installer with a signed driver from this location:


Best regards,

- Johannes
