How to make DRBD compatible to the Linux kernel

The Linux kernel’s interface towards device drivers is not set in stone. It evolves with the evolvement of Linux. Sometimes driven by hardware improvements, sometimes driven by general evolution of the code base. In tree drivers this is not a big issue since they get changed as the interfaces are modified, therefore are called “tree […]

LINSTOR grows beyond DRBD

For quite some time, LINSTOR has been able to use NVMe-oF storage targets via the Swordfish API. This was expressed in LINSTOR as a resource definition that contains a single resource with one backing disk (that is the NVMe-oF target) and one diskless resource (that is the NVMe-oF initiator). Layers in the storage stack In […]

The abbreviation stands for Non-Volatile Memory express, which isn’t very self-explanatory. It all began a few years back when NAND Flash started to make major inroads into the storage industry, and the new […]

Split Brain? Never Again! A New Solution for an Old Problem: DRBD Quorum

While attending OpenStack Summit in Atlanta, I sat in a talk about the difficulties of implementing High Availability (HA) clusters. At one point, the speaker presented a picture of a split-brain, discussed the challenges in resolving them, and implementing STONITH in certain environments. As many of you know, “split-brain” is a condition that can happen […]
