xfs_rtcp(8) System Manager's Manual xfs_rtcp(8)
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 speci-
fied xfs_rtcp will pad the destination file to a size which is
an even multiple of the filesystem block size. This is neces-
sary 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 ver-
sion 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.
