Dear DRBD users,
this is the first RC for v0.3.0 of drbd-reactor. With this release we
renamed the project from drbdd to drbd-reactor. We assume there are not
too many existing installations, but if so, copy your /etc/drbdd.toml to
/etc/drbd-reactor.toml and you should be good to roll
This version *requires* drbd-utils >=9.17.0, the RC of drbd-utils
released today will work.
The most exciting feature certainly is prometheus.io monitoring for
DRBD. We basically expose everything that is part of the events2 stream,
plus some higher level metrics. With that it is almost trivial to
generate useful grafana dashboards. Here is one showing parts of our
infrastructure, so you can get a feeling what this is about:
https://transfer.sh/FhbMX/drbd-reactor-prometheus.png
Note that this is a quick draft, we are sure you can build even more
exciting ones. A list of metrics can be found here[1]. These are the
obvious ones, we will add others based on user feedback.
The second change I want to mention explicitly is that it is now
possible to put toml snippets into /etc/drbd-reactor.d/. In the future
this will make it easy to dynamically create/delete promoter
configurations and relead drbd-reactor picking up plugins/unloading
them.
Please test. If there are no unexpected bugs, I will release the final
version in about a week from now.
Regards, rck
