\r\ncoreStorage | cs coreStorageVerb [...]\r\n                CoreStorage verbs can be used to create, manipulate and destroy CoreStorage volumes.\r\n\r\n                CoreStorage maintains a world of virtual disks, somewhat like RAID, in which one can easily\r\n                add or remove imported backing store disks, as well as exported usable volumes, to or from a\r\n                pool (or several pools). This provides the user with flexibility in allocating their hard-\r\n                ware; user or operating system data can span multiple physical disks seamlessly, for exam-\r\n                ple.\r\n\r\n                Apple CoreStorage defines four types of objects, instances of which are uniquely represented\r\n                by a UUID:\r\n\r\n                      o   Logical Volume Group (LVG)\r\n\r\n                      o   Physical Volume (PV)\r\n\r\n                      o   Logical Volume Family (LVF)\r\n\r\n                      o   Logical Volume (LV)\r\n\r\n                The Logical Volume Group (LVG) is the top or \"pool\" level; zero or more may exist during any\r\n                OS boot time session.\r\n\r\n                An LVG imports one or more Physical Volumes (PVs). A PV represents a device that feeds the\r\n                LVG storage space; a PV is normally real media but it can be a disk image or even an\r\n                AppleRAID Set. A disk offered to be a PV must be a partition and the encompassing scheme\r\n                must be GPT.\r\n\r\n                An LVG exports zero or more Logical Volume Families (LVFs). An LVF contains properties which\r\n                govern and bind together all of its descendant Logical Volumes (LVs). These properties pro-\r\n                vide settings for Full Disk Encryption (FDE) (such as whether the LVG is encrypted, which\r\n                users have access, etc) and other services.\r\n\r\n                A Logical Volume Family (LVF) exports one or more Logical Volumes (LVs).\r\n\r\n                A Logical Volume (LV) exports a dev node, upon which a file system (such as Journaled HFS+)\r\n                resides.\r\n\r\n                For more information on specifying device arguments, see the DEVICES section below.\r\n\r\n                CoreStorage is not a replacement for backing up your data.  Backups should be always be per-\r\n                formed on a regular basis and before modifying any CoreStorage volumes using these commands.\r\n\r\n                The following is a list of coreStorage sub-verbs with their descriptions and individual\r\n                arguments.\r\n\r\n                list [-plist | UUID]\r\n                           Display a tree view of the CoreStorage world for all current logical volume\r\n                           groups (LVGs) with member disks (PVs) and exported volumes (LVFs and LVs), with\r\n                           properties and status for each level.  If -plist is specified then a property\r\n                           list will be emitted instead of the formatted tree output; the UUIDs can be used\r\n                           with the diskutil coreStorage information verb to get properties for the object\r\n                           represented by that UUID.  If UUID is specified then an attempt is made to list\r\n                           only that UUID (whatever type of CoreStorage object it may represent).  The\r\n                           -plist and UUID arguments may not both be specified.\r\n\r\n                info | information [-plist] UUID | device\r\n                           Display properties of the CoreStorage object (LVG, PV, LVF, or LV) associated\r\n                           with the given CoreStorage UUID or disk.\r\n\r\n                convert device [-stdinpassphrase | -passphrase [passphrase]]\r\n                           Convert a regular Journaled HFS+ or Case-sensitive Journaled HFS+ volume (must be\r\n                           on a partition and within a GPT partitioning scheme) into a CoreStorage logical\r\n                           volume.\r\n\r\n                           If -passphrase is specified, the on-disk bytes will be encrypted. You will be\r\n                           prompted for a new passphrase interactively, or you can specify the passphrase on\r\n                           the command line. Alternatively, if you specify -stdinpassphrase the standard\r\n                           input is read for the passphrase so that a program could execute diskutil and\r\n                           send the passphrase through a pipe without having to expose it as a command-line\r\n                           parameter.\r\n\r\n                           The volume must be resizable (the above types are) and also mounted. Conversion\r\n                           is done live and in-place; targeting the boot volume is supported; as much of the\r\n                           conversion as possible is done before an eject or reboot is necessary.\r\n\r\n                           After slightly shrinking the source volume to make room for CoreStorage data\r\n                           structures at the end, its partition type is changed to Apple_CoreStorage and it\r\n                           becomes a CoreStorage Physical Volume.  A new CoreStorage Logical Volume Group is\r\n                           then created with this Physical Volume as the backing store, followed by the cre-\r\n                           ation of a Logical Volume Family and Logical Volume pair.\r\n\r\n                           At this point, the new CoreStorage PV\/LVG\/LVF\/LV stack is ready for use, although\r\n                           the \"old\" mountpoint must first be unmounted; yet it might not be unmountable.\r\n                           This will occur if the target (now the PV) is the current boot volume.\r\n\r\n                           Just before exiting, diskutil coreStorage convert will try to unmount the target\r\n                           disk (which is now the \"old\" mount point and the new PV). If successful (target\r\n                           is not the boot disk), the volume now becomes mounted from the LV. If unsuccess-\r\n                           ful (target is the boot disk), a reboot is necessary.\r\n\r\n                           At this point, if no encryption was specified, all is done. Otherwise, the bytes-\r\n                           on-disk will begin to be encrypted in-place by CoreStorage automatically \"in the\r\n                           background\" while the PV\/LVG\/LVF\/LV stack continues to be usable.
