+LVM
+===
+
+Description
+-----------
+
+The `lvm` role configures the Logical Volume Manager.
+
+Currently this role is only used to disable the `use_devicesfile` option in
+`lvm.conf`.  This was enabled by default starting in RHEL 9.0, and rendered
+some of my systems unbootable after the 9.2 upgrade.
+
+
+Variables
+---------
+
+This role **accepts** the following variables:
+
+Variable              | Default | Description
+----------------------|---------|------------
+`lvm_use_devicesfile` | `no`    | Enables use of the LVM [devices file](https://man7.org/linux/man-pages/man8/lvmdevices.8.html)
+
+
+Usage
+-----
+
+Example playbook:
+
+````yaml
+- name: configure lvm
+  hosts: all
+  roles:
+    - role: lvm
+      vars:
+        lvm_use_devicesfile: no
+````
