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
R target ,
the final argument (the
R 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
R WILL CAUSE CORRUPTION
on the data partition.
As such, this command is made available for curious
DEVELOPERS ONLY
at this point in time.
