My setup has two storage nodes, each with 2x nvme drives mirrored with mdadm, an lvm on that, and then drbd. In addition I have a VM running on TrueNAS as a diskless witness.
The two storage nodes are connected with a dedicated 25Gb link.
However, sometimes container backups will fail. It seems to happen when both hypervisors start a backup at the same time. It’s usually not the same container that fails. When failed I have to manually remove the snapshot and snapshot related resources.
Any ideas?
