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 mul‐
              tiple 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 parti‐
       tion WILL CAUSE CORRUPTION on the data partition. As such, this command is made available for curious DEVELOP‐
       ERS ONLY at this point in time.
