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

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.

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.
