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

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.
