xfs_rtcp(8)                            System Manager's Manual                           xfs_rtcp(8)

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 ex‐
       ists.

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.
