-You can create the LVM setup with [pvcreate](https://linux.die.net/man/8/pvcreate), [vgcreate](https://linux.die.net/man/8/vgcreate), [lvcreate](https://linux.die.net/man/8/lvcreate), and [lvconvert]([https://linux.die.net/man/8/pvcreate](https://linux.die.net/man/8/lvconvert)) traditionally.

 **Setting up the LVM cache**
 
-First, we create physical volumes for our devices, and check that it worked
-correctly:
-
-```
-sudo pvcreate ${VOLUME} ${DEVA} ${DEVB}
-sudo pvs
-```
-
-Then, we create a volume group with our three physical devices. In that volume
-group, we create three logical volumes: one for the data, another for the cache
-and the last one for the cache's metadata. Then we check that everything worked
-as expected.
-
-```
-sudo vgcreate cache-layer-vg ${VOLUME} ${DEVA} ${DEVB}
-sudo lvcreate -l 100%FREE -n data cache-layer-vg ${VOLUME}
-sudo lvcreate -L 700G -n cachedisk cache-layer-vg
-sudo lvcreate -L 16G -n metadisk cache-layer-vg
-sudo lvs
-```
-
-Now we need to turn those logical volumes into the actual cache. First we
-attach the metadata to the cache and then the cache to the data.
-
-```
-sudo lvconvert --type=cache-pool /dev/cache-layer-vg/cachedisk --poolmetadata  /dev/cache-layer-vg/metadisk
-sudo lvconvert --type cache /dev/cache-layer-vg/data --cachepool /dev/cache-layer-vg/cachedisk
-sudo lvs
-```
-
-With that, we've set up the data volume to be cached with our SSD disks. We can
-now format it and mount it:
-
-```
-sudo mkfs.ext4 /dev/cache-layer-vg/data
-sudo mkdir /var/www
-sudo mount /dev/cache-layer-vg/data /var/www
-```

 For Flatcar you could use a butane configuration file for the same that would be transpiled to ignition for the same purpose (upload a script for your setup based on above somewhere):
