.SH DESCRIPTION
|
|
.B mkfs.btrfs
|
|
is used to create an btrfs filesystem (usually in a disk partition, or an array
|
|
of disk partitions).
|
|
.I device
|
|
is the special file corresponding to the device (e.g \fI/dev/sdXX\fP ).
|
|
If multiple \fI devices \fP are specified, btrfs is created
|
|
spanning across the specified \fI devices\fP.
|
|
.SH OPTIONS
|
|
.TP
|
|
\fB\-A\fR, \fB\-\-alloc\-start \fIoffset\fR
|
|
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.
|
|
.TP
|
|
\fB\-b\fR, \fB\-\-byte\-count \fIsize\fR
|
|
Specify the size of the resultant filesystem. If this option is not used,
|
|
mkfs.btrfs uses all the available storage for the filesystem.
|
|
.TP
|
|
\fB\-d\fR, \fB\-\-data \fItype\fR
|
|
Specify how the data must be spanned across the devices specified. Valid
|
|
values are raid0, raid1, raid10 or single.
|
|
.TP
|
|
\fB\-l\fR, \fB\-\-leafsize \fIsize\fR
|
|
Specify the leaf size, the least data item in which btrfs stores data. The
|
|
default value is the page size.
|
|
.TP
|
|
\fB\-L\fR, \fB\-\-label \fIname\fR
|
|
Specify a label for the filesystem.
|
|
.TP
|
|
\fB\-m\fR, \fB\-\-metadata \fIprofile\fR
|
|
Specify how metadata must be spanned across the devices specified. Valid
|
|
values are raid0, raid1, raid10 or single.
|
|
.TP
|
|
\fB\-n\fR, \fB\-\-nodesize \fIsize\fR
|
|
Specify the nodesize. By default the value is set to the pagesize.
|
|
.TP
|
|
\fB\-s\fR, \fB\-\-sectorsize \fIsize\fR
|
|
Specify the sectorsize, the minimum block allocation.
|
|
.TP
|
|
\fB\-V\fR, \fB\-\-version\fR
|
|
Print the \fBmkfs.btrfs\fP version and exit.
|
|
.SH AVAILABILITY
|
|
.B mkfs.btrfs
|
|
is part of btrfs-progs. Btrfs is currently under heavy development,
|
|
and not suitable for any uses other than benchmarking and review.
