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
              specified xfs_rtcp will pad the destination file to a size which
              is an even multiple of  the  filesystem  block  size.   This  is
              necessary  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
       version  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.
