Dear LINBIT SDS on Kubernetes users, We've recently released version 1.10.0 of our Operator.
This release contains small improvements to the Operator, a new option to share the DRBD configuration directory between containers and hosts, and the usual updates to the container images. The updated LINSTOR 1.20.0 release contains some improvements to the k8s database backend. These improvements drastically improve performance when the cluster contains a moderate to high number of resources. In related news, if you have been following the DRBD 9.2.0 release, you will have noticed mention of DRBD now supporting running in the container network. This requires some deeper changes to the way we deploy LINBIT SDS on Kubernetes. To get a preview of how these changes will look like, you can check out the work-in-progress "v2" Piraeus Operator. [1] This new Operator version will be developed in parallel with the existing "v1.X" versions, until feature parity is reached and we have an acceptable migration story. Until then, feel free to leave feedback or feature requests on github. [2] The new chart is available from https://charts.linstor.io. New images are available from drbd.io. The usual upgrade procedure applies: $ helm repo update $ helm upgrade linstor-op linstor/linstor -f orig.yaml An updated User's Guide with detailed instructions is available. For more information, please take a look at the upgrade guide. [3] Source code is, as always, available upstream.

This will still work on IPv4 only systems with IPv6 disabled via sysctl. - Default images: * LINSTOR 1.20.0 * DRBD 9.1.11 * DRBD Reactor 0.9.0 * external CSI images upgraded to latest versions ### Fixed - Comparing IP addresses for registered components uses golang built-in net.IP type. - Restoring satellites after eviction only happens if the node is ready. _______________________________________________ Star us on GITHUB: https://github.com/LINBIT drbd-user mailing list drbd-user@lists.linbit.com https://lists.linbit.com/mailman/listinfo/drbd-user
