Volumes

The lifecycle of a logical volume, from provisioning to deletion, is covered under Usage. This section covers what is operated on an existing volume: moving it between storage nodes, re-establishing its NVMe-oF connections, reclaiming the blocks its filesystem no longer uses, and capping the performance it may consume.

Topic	Purpose
Volume Migration	Moving a logical volume between storage nodes while it stays online.
Reconnecting Logical Volume	Re-establishing the NVMe-oF connections of a volume after a node outage.
Trimming a Filesystem	Reclaiming the unused blocks of a thin-provisioned logical volume.
Quality of Service Limits	Capping the IOPS and the throughput of a volume or a storage pool.
QoS Service Classes	Assigning volumes to a service class to guarantee its share of the cluster.
