The Linstor client needs to be installed and it needs to be configured on the nodes used by the controller. It supports most pool/vol commands, except for pool-build/pool-delete and provides a block device in RAW file mode. Linstor supports more than just DRBD so it would also be possible to have it provide LVM, ZFS or NVME volumes, but the common case will be to provide DRBD volumes in a cluster. Sample pool XML: linstor libvirtgrp element must point to an already created LINSTOR resource-group, which is used to spawn resources/volumes. attribute should be the local linstor node name, if missing it will try to get the hosts uname and use that instead.

The valid volume types are the same as for the directory pool.

LINSTOR pool

+

+ This provides a pool using the LINSTOR software-defined-storage. + LINSTOR can provide block storage devices based on DRBD or basic + LVM/ZFS volumes. +

+ +

+ To use LINSTOR in libvirt, setup a working LINSTOR cluster, document= ation + for that is in the LINSTOR Users-guide. + And create a resource-group that will be used by libvirt, also make = sure + the resource-group is setup in a way so that all nodes you want to u= se with libvirt + will create a resource. So either use diskless-on-remaining or make = sure + replica-count is the same as you have nodes in your cluster. +
