[DRBD-user] DRBD9 not building on PVE6.1

[Gianni Milo]

Hello,

In general, there's no need to be a developer (I'm not) to setup
DRBD9/LINSTOR on PVE.
LINBIT have made things easy enough, for the average sysadmin to get your
cluster up and running without any special knowledge (apart from the
obvious Linux sysadmin skills that one must have of course to maintain such
setup).

The issues I had building drbd9 were due to the fact that my pve cluster
nodes, do not have direct access to the internet. That is required for
building recent drbd9 kernel module versions on pve, due to some changes in
its code base. So, as soon as your pve nodes can access http/https traffic
on the internet, then you should be fine.
Even when your pve cluster nodes do not have internet access, it's still
possible to build drbd9 kernel modules on a different machine (which has
internet access) and then manually move them to the production server, as
mentioned previously in this post. What I usually do to further control
drbd/pve stability is to prevent automatic kernel upgrades, which can
sometimes lead to a broken system.

You can follow the steps described in the blog post below and the Linstor
documentation, for more details in setting up your cluster:
https://www.linbit.com/en/linstor-setup-proxmox-ve-volumes/
https://docs.linbit.com/docs/linstor-guide/#ch-proxmox-linstor

Last but not least, both pve and linbit offer paid support plans.

Hope this helps ...

Regards,
G.
