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.
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.
