Before volume group snapshots, a Kubernetes operator could only take snapshots of one persistent […]
Becoming More Accessible to Windows Users

The first was about Hyper-V virtual machines running with their virtualized backing disks on WinDRBD, the VMs managed by drbd-reactor, and a live migration controlled by drbd-reactor.

This feature enables multiple pods to mount and write to the same LINSTOR-backed persistent volume simultaneously. RWX support is a hard requirement for applications that require shared storage, […]
