drbd-driver-loader

This is a collection of Piraeus container images containing the DRBD kernel source code that can be used to compile DRBD kernel modules from source and load them into the host kernel.

How to use

Note that for this to work, the kernel headers are bind-mounted from the host to the container. Therefore, you need to install the according headers on the host system (e.g., yum install kernel-devel).

LINBIT provides containers that can directly install pre-built kernel modules on the host without compiling/the requirement to have kernel headers installed.

RHEL/Centos systems:

docker run -it --rm --privileged \
   -v /lib/modules:/lib/modules:ro -v /usr/src:/usr/src:ro \
   piraeusdatastore/drbd9-centos7:latest

We provide loader images for Ubuntu Bionic, and RHEL/CentOS 7/8.

Installing the kernel objects to the host

This feature is available since version 9.0.20. One has to mark the bind mounted /lib/modules directory writable (by removing the ':ro'), and set the environment variable "LB_INSTALL" to "yes". For RHEL/Centos this looks like this:

docker run -it --rm --privileged \
   -v /lib/modules:/lib/modules -v /usr/src:/usr/src:ro \
   -e "LB_INSTALL=yes" \
   piraeusdatastore/drbd9-centos7:latest

Registries

How does this differ from LINBIT's LINSTOR?

The containers we provide in the Piraeus project are Debian based and packages get installed from a PPA. These are maintained at a best effort basis, but make sure to understand the differences between these packages and the ones provided by LINBIT for its customers.

Container used for module loading are based on Centos/Ubuntu.

Additionally, container images provided by LINBIT as commercal offer on drbd.io, are based on RHEL/UBI images and are for example OpenShift certified.
