Ideally, you would [configure the LINSTOR controller to be highly available](https://linbit.com/drbd-user-guide/linstor-guide-1_0-en/#s-linstor_ha).

However, if the LINSTOR controller is unavailable in Proxmox, any running VMs on the other nodes are unaffected. On the remaining nodes, the LINSTOR storage is still available, DRBD is still replicating, etc. However, you can’t provision new storage, migrate VMs, or perform any actions in the cluster that require the LINSTOR controller.
