## What it is
TopoLVM is a capacity-aware CSI (Container Storage Interface) plugin for Kubernetes that provisions persistent volumes using LVM2 on Linux nodes. It implements local persistent volumes with dynamic provisioning, topology-aware scheduling, raw block volumes, volume expansion, and Prometheus metrics.

## Use cases
- provision local persistent volumes on kubernetes nodes with lvm
- dynamically create pvcs backed by lvm logical volumes
- schedule pods to nodes with the most free storage capacity
- expose raw block devices to containers in kubernetes
- expand persistent volumes without downtime
- export volume usage metrics to prometheus
- run stateful workloads with local storage on bare metal kubernetes

## When to choose
- you run kubernetes on bare metal or VMs with LVM2-managed local disks
- you need dynamic provisioning of local persistent volumes with topology awareness
- you want capacity-aware pod scheduling based on remaining storage
- you need raw block volumes or volume expansion on local storage

## When to avoid
- you need shared or replicated storage across nodes rather than node-local volumes
- your cluster runs on non-Linux nodes or hosts without LVM2
- you want cloud-managed storage like EBS or Persistent Disk instead of local disks
