xfs_rtcp: XFS realtime copy command

Command to display xfs_rtcp manual in Linux: $ man 8 xfs_rtcp

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.

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.
