xfs_rtcp(8)                System Manager's Manual               xfs_rtcp(8)

NAME         top

       xfs_rtcp - XFS realtime copy command

SYNOPSIS         top

       xfs_rtcp [ -e extsize ] [ -p ] source ... target
       xfs_rtcp -V

DESCRIPTION         top

       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         top

       -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         top

CAVEATS         top

       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.
