GEOM_LINUX_LVM(4)

💖 GEOM_LINUX_LVM(4) 💖

okay bestie, so this one lives in the Kernel Interfaces Manual section (section 4, the ~spicy~ kernel one), and it's literally called geom_linux_lvm — which is GEOM based Linux LVM logical volume mapping. yes you read that right, Linux volumes on your BSD. iconic behavior honestly.

✨ NAME ✨

geom_linux_lvm — GEOM based Linux LVM logical volume mapping 🦋

---

🌸 SYNOPSIS 🌸

so there's two ways to get this baby running, and it's giving choose your own adventure.

Option one, the "I compile my own kernel" main character route — drop this line into your kernel configuration file:

options GEOM_LINUX_LVM

Option two, the "load it as a module at boot" bestie route — put this line in loader.conf(5):

geom_linux_lvm_load="YES"

ngl both are valid, pick whichever matches your vibe 💅

🎀 DESCRIPTION 🎀

so the geom_linux_lvm framework is out here doing the absolute most — it provides support for mapping Linux LVM volumes to GEOM providers. like, translating the whole thing for you. 🧚

as of right now, geom_linux_lvm currently supports linear stripes with segments on one or more physical disks. that's the tea. ☕

the parser? oh she READS. she's able to read LVM2 Text Format metadata, the logical volumes will be assembled and made available under /dev/linux_lvm/. absolutely serving them up for you. 👑

⚠️ okay but here's the part where you need to listen, bestie: the metadata is read-only. logical volumes cannot be allocated or resized. no cap. so don't come at her trying to change things, she will not be doing that. 🙈

🔥 EXAMPLES 🔥

wanna see which geom_linux_lvm devices are available? say less. run this:

# 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. vg1 with its two providers linux_lvm/vg1-home and linux_lvm/vg1-logs, both chunky at 4294967296 bytes (4.0G) each, Sectorsize: 512, Mode: r0w0e0 — and one consumer, ada0s1, clocking in at 80023716864 (75G). she ate. 💖
