This does not need to be a physical disk, but can also be another RAID, be it an mdraid, fakeraid, hardware raid, a virtual disk on a SAN or otherwisee or a partition on one of those. Where I write ext4, the samme applies to ext2 and ext3.Ī PV is the "physical" parts. In my experience, the defaults work well for most usecases. All commands are given as examples, and all of them can be fine-tuned using extra flags in need of so. There can be multiple PVs, VGs and LVs, depending on requirement. LVM broadly consists of three elements, the "physical" devices (PV), the volume group (VG) and the logical volume (LV). Keep in mind that fakeraid should be avoided unless you really need it, like in conjunction with dual-booting linux and windows on fakeraid. LVM is designed to be an abstraction layer on top of physical drives or RAID, typically mdraid or fakeraid.
