      Description

      There should be a clear warning about the IO performance degradation when using LVM while the snapshot exists.

      https://wiki.mongodb.com/display/KB/Filesystem+vs+LVM+snapshots

      I also believe that is important to clarify that LVM works on a block level not at filesystem level like BTRFS or ZFS.
