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
- -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.
- -V
-
Prints the version number and exits.
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.
