DRBD 9.0.18 has officially been released and introduces two new features in addition to several bug solutions. To start, we have extended the DRBD Quorum to no longer require three replicas of your data. Now, you can have a third arbitrator node without the performance impact of an additional replica. To achieve this, we utilize DRBD’s diskless node feature.
In addition, we have added the ability to store DRBD meta-data on PMEM/NVDIMMs. By storing the meta-data in this way, you’ll be able to see a 3x performance increase, depending on your workloads.
Keep an eye out for our upcoming blog posts that highlight these new features!
