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 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  speci-
              fied  xfs_rtcp  will pad the destination file to a size which is
              an even multiple of the filesystem block size.  This  is  neces-
              sary 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  ver-
       sion  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.
