NAME

       xfs_rtcp - XFS realtime copy command

SYNOPSIS

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

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.

       -V     Prints the version number and exits.

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.
