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 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.
