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.
