mkfs.btrfs

MKFS.BTRFS(8)						      System Manager's Manual						     MKFS.BTRFS(8)

NAME

       mkfs.btrfs - create an btrfs filesystem

SYNOPSIS

       mkfs.btrfs [ -A alloc-start ] [ -b byte-count ] [  -d data-profile ] [  -l leafsize ] [	-L label ] [  -m metadata profile ] [  -n nodesize
       ] [  -s sectorsize ] [  -h ] [  -V ]  device [  device ... ]

DESCRIPTION

       mkfs.btrfs is used to create an btrfs filesystem (usually in a disk partition, or an array of disk partitions).	device is the special file
       corresponding  to  the  device  (e.g  /dev/sdXX	).   If  multiple   devices  are specified, btrfs is created spanning across the specified
       devices.

OPTIONS

       -A, --alloc-start offset
	      Specify the offset from the start of the device to start the btrfs filesystem. The default value	is  zero,  or  the  start  of  the
	      device.

       -b, --byte-count size
	      Specify the size of the resultant filesystem. If this option is not used, mkfs.btrfs uses all the available storage for the filesys-
	      tem.

       -d, --data type
	      Specify how the data must be spanned across the devices specified. Valid values are raid0, raid1, raid10 or single.

       -l, --leafsize size
	      Specify the leaf size, the least data item in which btrfs stores data. The default value is the page size.

       -L, --label name
	      Specify a label for the filesystem.

       -m, --metadata profile
	      Specify how metadata must be spanned across the devices specified. Valid values are raid0, raid1, raid10 or single.

       -n, --nodesize size
	      Specify the nodesize. By default the value is set to the pagesize.

       -s, --sectorsize size
	      Specify the sectorsize, the minimum block allocation.

       -V, --version
	      Print the mkfs.btrfs version and exit.

AVAILABILITY

       mkfs.btrfs is part of btrfs-progs. Btrfs is currently under heavy development, and not suitable for any uses other  than  benchmarking  and
       review.	Please refer to the btrfs wiki http://btrfs.wiki.kernel.org for further details.
