команда копирования в реальном времени XFS (XFS realtime copy command)
Имя (Name)
xfs_rtcp - XFS realtime copy command
Синопсис (Synopsis)
xfs_rtcp [ -e extsize ] [ -p ] source ... target
xfs_rtcp -V
Описание (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.
Параметры (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.

Предостережение (Caveat)
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.
