NAME
       xfs_rtcp - XFS realtime copy command

SYNOPSIS
       xfs_rtcp [ -e extsize ] [ -p ] source ... target

DESCRIPTION
       xfs_rtcp	 copies a file to the realtime partition on an XFS filesystem.
       If there is more than one source and target, the	 final	argument  (the
       target) must be a directory which already exists.

OPTIONS
       -e extsize
	      Sets the extent size of the destination realtime file.

       -p     Use  if  the  size of the source file is not an even multiple of
	      the block size of the destination filesystem. When -p is	speci‐
	      fied  xfs_rtcp  will pad the destination file to a size which is
	      an even multiple of the filesystem block size.  This  is	neces‐
	      sary since the realtime file is created using direct I/O and the
	      minimum I/O is the filesystem block size.

SEE ALSO
       xfs(5), mkfs.xfs(8), mount(8).

CAVEATS
       Currently, realtime partitions are not supported under the  Linux  ver‐
       sion  of	 XFS, and use of a realtime partition WILL CAUSE CORRUPTION on
       the data partition. As such, this command is made available for curious
       DEVELOPERS ONLY at this point in time.
