NEWFS_APFS(8) BSD System Manager's Manual NEWFS_APFS(8)NAME
newfs_apfs -- construct a new APFS volume
SYNOPSIS
newfs_apfs [-o options] [-i] [-b block-size] [-s volume-size | -q volume-quota -r volume-reserve] [-v volume-name] [-E | -P] [-R role]
special
newfs_apfs -C [-o options] [-i] [-b block-size] special
newfs_apfs -A [-o options] [-i] [-s volume-size | -q volume-quota -r volume-reserve] [-v volume-name] [-E | -P] [-R role] special
newfs_apfs [-o options] [-i] [-s volume-size | -q volume-quota -r volume-reserve] [-v volume-name] [-E | -P] [-R role] special
DESCRIPTION
The newfs_apfs command creates a new APFS container on the device and/or adds a new APFS volume to a container.
The first, more traditional, form of newfs_apfs formats the given special as a container with a single volume inside it. The second form
creates a container only, with no volumes. The third form is used to non-destructively add additional volumes inside an existing container.
The fourth form reformats an existing volume by effectively deleting and re-creating it; in this usage (only) special indicates a volume
inside the container.
The special parameter should be the path to a disk device node, such as /dev/disk1s2, although can be specified as simply disk1s2.
The options are as follows:
-b block-size The block size of the container. All volumes within this container will use this block size. The default is 4096 bytes.
-o options Additional (undocumented) formatting options.
-i Creates a case-insensitive volume. This is the default on macOS.
-e Creates a case-sensitive volume.
-U uid The UID of the root volume. Defaults to current UID.
-G uid The GID of the root volume. Defaults to current GID.
-q volume-quota Places a quota, or upper limit, on the size of the volume. If specified then no more than this much space will be used
for its content, even if there is additional free space in the container; however it is not guaranteed that the entire
quota will always be available. By default a volume has no assigned quota.
-r volume-reserve Reserves an amount of space for this volume. If specified it is guaranteed that at least this much space will be
available for its content; the volume may also grow beyond this size (up to its quota limit, if any) if additional free
space in the container. By default a volume has no assigned reserve.
-s volume-size The fixed size of the volume. If specified then the volume is guaranteed that exactly this much space will be available
for its content. Setting -s is equivalant to setting both -q and -r to that same value. If not specified then the
available space is dynamic and determined by the usage of other volumes within the same container (space-sharing).
-v volume-name The name of the volume. The default is "untitled".
-A Add a volume to an existing container. There is a limit to the number of volumes that may reside inside a container.
-C Create a container only, with no volume. newfs_apfs -A may be used later to format volumes inside that container.
-E Enable volume encryption. The volume metadata is also encrypted.
-F special Format as a Fusion device (with the secondary device specified here).
-R role Set the OS "role" of the volume within the container. The role may be one of the following characters:
b PreBoot - will contain information used to help boot System volumes
r Recovery - will contain the RecoveryOS
v VM - will contain swapfiles and hibernate image
DIAGNOSTICS
The newfs_apfs utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
The following formats a new container and a volume named "Macintosh" on the /dev/disk1s2 device:
newfs_apfs -v Macintosh disk1s2
And then this adds another volume, named "Data" with a fixed size of 100 GB, to that container:
newfs_apfs -v Data -s 100g -A disk1s2

The newfs_apfs utility first appeared in OS X 10.12.
