xfs_rtcp(8) - Linux man page
Name
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.

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.
