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.
