💅 GEOM_LINUX_LVM(4) 💅

okay bestie, this page is from the Kernel Interfaces Manual, and it’s all about geom_linux_lvm — the GEOM-based Linux LVM logical volume mapping situation. No cap, it’s giving kernel-interface realness ✨

✨ NAME ✨

geom_linux_lvm — GEOM based Linux LVM logical volume mapping 💖

🛠️ SYNOPSIS 🛠️

So if you wanna compile this driver into the kernel, put this line in your kernel configuration file:

             options GEOM_LINUX_LVM

Or, alternatively, to load the driver as a module at boot time, put this line in loader.conf(5):

             geom_linux_lvm_load="YES"

Both roads lead to the driver, bestie — choose your vibe 💅

💖 DESCRIPTION 💖

The geom_linux_lvm framework provides support for mapping Linux LVM volumes to GEOM providers. geom_linux_lvm currently supports linear stripes with segments on one or more physical disks. The parser is able to read LVM2 Text Format metadata, the logical volumes will be assembled and made available under /dev/linux_lvm/. The metadata is read-only, logical volumes cannot be allocated or resized.

lowkey important: metadata is read-only, so no allocating or resizing logical volumes here — periodt 🫶

🌈 EXAMPLES 🌈

To view which geom_linux_lvm devices are available:

             # geom linux_lvm list
             Geom name: vg1
             Providers:
             1. Name: linux_lvm/vg1-home
                Mediasize: 4294967296 (4.0G)
                Sectorsize: 512
                Mode: r0w0e0
             2. Name: linux_lvm/vg1-logs
                Mediasize: 4294967296 (4.0G)
                Sectorsize: 512
                Mode: r0w0e0
             Consumers:
             1. Name: ada0s1
                Mediasize: 80023716864 (75G)
                Sectorsize: 512
                Mode: r0w0e0

Look at that output — providers, consumers, mediasizes, sectorsizes, modes — it’s all right there, iconic 😭💖
