Kubernetes High Availability for Stateful Workloads

LINBIT is a company with deep roots in Linux High Availability (HA). Because of this, LINBIT has some opinions on what HA is, and how it can be achieved. Kubernetes’ approach to HA generally involves sprawling many replicas of an application across many cluster nodes, therefore making it less impactful when a single node or […]

Cheap Votes: DRBD Diskless Quorum

One of the most important considerations when implementing clustered systems is ensuring that a cluster remains cohesive and stable given unexpected conditions. DRBD already has fencing mechanisms and even a system of quorum, which is now capable of using a diskless arbitrator to break ties without requiring additional storage beyond that of two nodes. Quorum […]

Key/Value Store in LINSTOR

Recently we introduced a Key/Value store in LINSTOR and exposed it in a developer-friendly way in the Python API (python-linstor). The first question is why would one want such a Key/Value store in LINSTOR when there are many high performance implementations such as etcd. The request for a K/V store was mainly driven by LINSTOR […]
