LVM provides a number of special features such as creating snapshots, raid for single Logical Volumes and much more. If you want to use these devices on bootup, the associated <code>dm-*</code> kernel module must be provided in the initrd (see for example {{Issue|33646}}) . This is a non-exhaustive list of features and the corresponding kernel module to put into your <code>configuration.nix</code>: | LVM provides a number of special features such as creating snapshots, raid for single Logical Volumes and much more.
