+.SH "NAME"
+mkswap \- set up a Linux swap area
+.SH "SYNOPSIS"
+.sp
+\fBmkswap\fP [options] \fIdevice\fP [\fIsize\fP]
+.SH "DESCRIPTION"
+.sp
+\fBmkswap\fP sets up a Linux swap area on a device or in a file.
+.sp
+The \fIdevice\fP argument will usually be a disk partition (something like \fI/dev/sdb7\fP) but can also be a file. The Linux kernel does not look at partition IDs, but many installation scripts will assume that partitions of hex type 82 (LINUX_SWAP) are meant to be swap partitions. (\fBWarning: Solaris also uses this type. Be careful not to kill your Solaris partitions.\fP)
+.sp
+The \fIsize\fP parameter is superfluous but retained for backwards compatibility. (It specifies the desired size of the swap area in 1024\-byte blocks. \fBmkswap\fP will use the entire partition or file if it is omitted. Specifying it is unwise \- a typo may destroy your disk.)
+.sp
+After creating the swap area, you need the \fBswapon\fP(8) command to start using it. Usually swap areas are listed in \fI/etc/fstab\fP so that they can be taken into use at boot time by a \fBswapon \-a\fP command in some boot script.
+.SH "WARNING"
+.sp
+The swap header does not touch the first block. A boot loader or disk label can be there, but it is not a recommended setup. The recommended setup is to use a separate partition for a Linux swap area.
+.sp
+\fBmkswap\fP, like many others mkfs\-like utils, \fBerases the first partition block to make any previous filesystem invisible.\fP
+.sp
+However, \fBmkswap\fP refuses to erase the first block on a device with a disk label (SUN, BSD, ...).
+.SH "OPTIONS"
+.sp
+\fB\-c\fP, \fB\-\-check\fP
+.RS 4
+Check the device (if it is a block device) for bad blocks before creating the swap area. If any bad blocks are found, the count is printed.
+.RE
+.sp
+\fB\-f\fP, \fB\-\-force\fP
+.RS 4
+Go ahead even if the command is stupid. This allows the creation of a swap area larger than the file or partition it resides on.
+.sp
+Also, without this option, \fBmkswap\fP will refuse to erase the first block on a device with a partition table.

+.sp

+Specify a \fIlabel\fP for the device, to allow \fBswapon\fP(8) by label.
+.RE
+.sp
+\fB\-\-lock\fP[=\fImode\fP]
+.RS 4
+Use exclusive BSD lock for device or file it operates. The optional argument \fImode\fP can be \fByes\fP, \fBno\fP (or 1 and 0) or \fBnonblock\fP. If the \fImode\fP argument is omitted, it defaults to \fByes\fP. This option overwrites environment variable \fB$LOCK_BLOCK_DEVICE\fP. The default is not to use any lock at all, but it\(cqs recommended to avoid collisions with \fBsystemd\-udevd\fP(8) or other tools.

+== NAME
+
+mkswap - set up a Linux swap area
+
+== SYNOPSIS
+
+*mkswap* [options] _device_ [_size_]
+
+== DESCRIPTION
+
+*mkswap* sets up a Linux swap area on a device or in a file.
+
+The _device_ argument will usually be a disk partition (something like _/dev/sdb7_) but can also be a file. The Linux kernel does not look at partition IDs, but many installation scripts will assume that partitions of hex type 82 (LINUX_SWAP) are meant to be swap partitions. (*Warning: Solaris also uses this type. Be careful not to kill your Solaris partitions.*)
+
+The _size_ parameter is superfluous but retained for backwards compatibility. (It specifies the desired size of the swap area in 1024-byte blocks. *mkswap* will use the entire partition or file if it is omitted. Specifying it is unwise - a typo may destroy your disk.)
+
+After creating the swap area, you need the *swapon*(8) command to start using it. Usually swap areas are listed in _/etc/fstab_ so that they can be taken into use at boot time by a *swapon -a* command in some boot script.
+
+== WARNING
+
+The swap header does not touch the first block. A boot loader or disk label can be there, but it is not a recommended setup. The recommended setup is to use a separate partition for a Linux swap area.
+
+*mkswap*, like many others mkfs-like utils, *erases the first partition block to make any previous filesystem invisible.*
+
+However, *mkswap* refuses to erase the first block on a device with a disk label (SUN, BSD, ...).
+
+== OPTIONS
+
+*-c*, *--check*::
+Check the device (if it is a block device) for bad blocks before creating the swap area. If any bad blocks are found, the count is printed.
+
+*-f*, *--force*::
+Go ahead even if the command is stupid. This allows the creation of a swap area larger than the file or partition it resides on.
++
+Also, without this option, *mkswap* will refuse to erase the first block on a device with a partition table.
+
+*-q*, *--quiet*::
+Suppress output and warning messages.
+
+*-L*, *--label* _label_::
+Specify a _label_ for the device, to allow *swapon*(8) by label.
+
+*--lock*[=_mode_]::
+Use exclusive BSD lock for device or file it operates. The optional argument _mode_ can be *yes*, *no* (or 1 and 0) or *nonblock*. If the _mode_ argument is omitted, it defaults to *yes*. This option overwrites environment variable *$LOCK_BLOCK_DEVICE*. The default is not to use any lock at all, but it's recommended to avoid collisions with *systemd-udevd*(8) or other tools.
+
+*-p*, *--pagesize* _size_::
+Specify the page _size_ (in bytes) to use. This option is usually unnecessary; *mkswap* reads the size from the kernel.
+
+*-U*, *--uuid* _UUID_::
+Specify the _UUID_ to use. The default is to generate a UUID. The format of the UUID is a series of
+hex digits separated by hyphens, like this: "c1b9d5a2-f162-11cf-9ece-0020afc76f16". The UUID parameter
+may also be one of the following:
++
+*clear*;;
+clear the filesystem UUID
+*random*;;
+generate a new randomly-generated UUID
+*time*;;
+generate a new time-based UUID
+
+*-v*, *--swapversion 1*::
+Specify the swap-space version. (This option is currently pointless, as the old *-v 0* option has become obsolete and now only *-v 1* is supported. The kernel has not supported v0 swap-space format since 2.5.22 (June 2002). The new version v1 is supported since 2.1.117 (August 1998).)
+
+*--verbose*::
+Verbose execution. With this option *mkswap* will output more details about detected problems during swap area set up.
+
+include::man-common/help-version.adoc[]
+
+== ENVIRONMENT
+
+LIBBLKID_DEBUG=all::
+enables libblkid debug output.
+
+LOCK_BLOCK_DEVICE=<mode>::
+use exclusive BSD lock. The mode is "1" or "0". See *--lock* for more details.
+
+== NOTES
+
+The maximum useful size of a swap area depends on the architecture and the kernel version.
+
+The maximum number of the pages that is possible to address by swap area header is 4294967295 (32-bit unsigned int). The remaining space on the swap device is ignored.
