Building and "insmod" DRBD windows driver:
1.) Run
make
on the Linux box (from $HOME/Linbit/Work/wdrbd9)
2.) Run
make
on the Windows box (from $HOME/Linbit/Work/wdrbd9 (takes some while)
3.) Run
make install
on the Windows box (from $HOME/Linbit/Work/wdrbd9/converted-sources/drbd)
4.) Run (in an Administrator cmd.exe Console: to open it go to
C:\Windows\System32 in Explorer, Cmd-Click on cmd.exe
and select Run as Administrator)
INSTALL-DRBD-admin.bat
5.) To load the driver, do (from Adminstrator Console)
sc start drbd
DbgViewer will show output. To start DbgViewer go to
C:\drbd\DebugViewer and start DbgView.exe as Administrator
from Windows to Mac:
Start -> In Text field:
\\192.168.56.1
Right click: Cmd+Click
Gruppenrichtline: Start, type Gruppenrichtlinie
search cmd.exe - right click (Cmd+click) and select run as administrator
then
pnputil -a drbd.inf
eventvwr linbit-wdrbd
DebugView
C:\drbd\dbgview\DbgView.exe as Administrator

change path specs in .git file (not dir) in submodules to
relative path.
----
Sign with Linbit certificate (now integrated in Makefile, ignore this
section):
copy unsigned drbd.sys and drbd.cat to Windows 10: C:\to-sign
"C:\Program Files (x86)\Windows Kits\10\bin\10.0.16299.0\x64\signtool.exe" sign /v /ac "C:\cert\DigiCert High Assurance EV Root CA.crt" /a /t http://timestamp.digicert.com "c:\to-sign\drbd.cat"
"C:\Program Files (x86)\Windows Kits\10\bin\10.0.16299.0\x64\signtool.exe" sign /v /ac "C:\cert\DigiCert High Assurance EV Root CA.crt" /a /t http://timestamp.digicert.com "c:\to-sign\drbd.sys"
copy files back to $LINBIT_COMPILE_DIR/signed
Use windrbd-install-signed.SED.in to build package (will take drbd.sys and
drbd.cat from signed directory).
-----
Make releases
-------------
Update: Driver signing has changed. We use Microsoft partner
center and HLK Studio to obtain a Microsoft signature, this
makes WinDRBD also load on SecureBoot systems. So most of
the following can be ignored.
Update: can now be built with Windows 10 physical machine, which
makes everything much more easy.
Run cygwin update
Update cygwin1.dll to newest version (in inno-setup/cygwin-binaries)
git checkout master
git merge jt/latest-feature-branch
On Linux:
make clean && make V=1
And check in converted-sources if source changed (git diff)
Document changes in WHATSNEW.md
Add entry to README.md
git add README.md
git commit -m "Release 1.0.X"
git tag windrbd-1.0.X
git describe --tags
(should display the version number)
build drbd-utils-windows (make package takes drbdadm, ... from build dir)
On Windows 10 physical machine (with USB dongle attached):
mount ewdk (double click EWDK_rs5_... ISO on Desktop)
make clean && make package R=1
upload install-windrbd-1.0.X-signed.exe to google drive windrbd-in folder
git push --all origin
git push --tags origin
phil:
git push master github
git push master github --tags
copy signed exe to website

Add:
The options from
http://ipxe.org/howto/dhcpd#pxe_chainloading
And further down:
# solution works 'for me'. It tests for iSCSI, where sanboot http://...
# is sufficient. iscsi seems to be closely related to sanboot. The
# off the shelf VirtualBox iPXE build does not have iscsi enabled,
# therefore we load a custom built image which then executes the
# sanboot command.
if exists ipxe.iscsi {
filename "";
option root-path "http://192.168.56.102/cgi-bin/drbd.cgi";
} else {
filename "http://192.168.56.102/~johannes/ipxe/ipxework.pxe";
}
Also add windrbd-root option:
option ipxe.windrbd-root code 196 = string;
After changes restart dhcp server with
sudo service isc-dhcp-server restart
DisklessClient should now boot into windows without need to type
boot commands.
Configure fixed IP Address:
host diskless-client {
hardware ethernet 08:00:27:b2:a9:32;
fixed-address 192.168.56.150;
}
Configure dynamic range (don't do this, DRBD needs a fixed address):
subnet 192.168.56.0 netmask 255.255.255.0 {
range 192.168.56.160 192.168.56.250;
}
Not sure yet how it works with 2 networks (iPXE of VirtualBox seems
not to try the second network if something with the first network
fails, however this works with the custom built iPXE)
To make dhcp work the network adapter must be allowed promiscious
mode (see advanced settings of network adapter in VirtualBox network
adapter settings).

Booting
See the tech-guide on booting
Neccessary steps:
Install WinDRBD Bus driver
Device manager: add legacy hardware: windrbd.inf
Install WinDRBD Disk driver
(else will not call START_DEVICE PnP request)
To do so install windrbd with boot device and wait for
primary disabled and do Update driver software in
device manager (windrbd-disk.inf).
Do a drbdadm up of a dummy device (does not need to
have backing storage or connection)
TODO: Maybe it is also possible to just doubleclick the
inf file which makes things far more easier.
Install windrbd driver with boot and wait for primary in
windrbd I/O requests (not windrbd_pnp, but windrbd_create)
# Also: Disable UDP logging (NO_NET_PRINTK) in printk-to-syslog
Enable NIC driver
E1 something for my VirtualBox
Enable AFD driver (unclear if really needed)
Enable Broadcom drivers (unclear if really needed)
Currently: Assign a fixed IP address (must match the one in DRBD
config). TODO: which driver to load on boot to make
DHCP work?
Also Disable Network Discovery (else there is a short time gap
in which network is down and Windows needs to access
boot device in order to continue):
(from https://social.technet.microsoft.com/Forums/en-US/675520ed-fe25-455e-a86e-fdb833903b10/windows-takes-an-exceptionally-long-time-to-establish-a-network-connection-after-booting

Disable NDIS lightweight filter for boot NIC:
https://support.microsoft.com/en-us/help/976042/windows-may-fail-to-boot-from-an-iscsi-drive-if-networking-hardware-is

Few things to note:
1) Make sure you are not on a Virtual Machine or remote accessing the device you are installing the token.
2) With the token plugged into the device go to Device manager and uninstall all Aladdin, Rainbow Microsoft USBCCID, Safenet and the USB token under “Universal Bus Controllers” and any related categories ("Smart Card Readers").
3) Unplug Token.
4) Uninstall Safenet drivers from the programs.
5) Reboot the device
6) Reinstall the latest Safenet drivers as administrator.
7) Re plug in token.
