xfs_rtcp - XFS realtime copy command

       Currently,  realtime  partitions  are not supported under the Linux version of XFS, and use of a realtime
       partition WILLCAUSECORRUPTION on the data partition. As  such,  this  command  is  made  available  for
       curious DEVELOPERSONLY at this point in time.

                                                                                                     xfs_rtcp(8)

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.

-eextsize
              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.
