The ceph-volume lvm list command is used to list information about Logical Volumes (LVs) managed by Ceph's volume management tool (ceph-volume) in a Ceph storage cluster. This command is used to gather information about the OSDs (Object Storage Daemons) that utilize LVM (Logical Volume Manager) as their storage backend.
When you run the ceph-volume lvm list command, it will provide you with a list of information about the LVM-based OSDs in your Ceph cluster, such as their IDs, UUIDs, VG (Volume Group) name, LV (Logical Volume) name, size, and various other details.
