6 xfs_rtcp - XFS realtime copy command
7
9 xfs_rtcp [ -e extsize ] [ -p ] source ... target
10 xfs_rtcp -V
11
13 xfs_rtcp copies a file to the realtime partition on an XFS filesystem.
14 If there is more than one source and target, the final argument (the
15 target) must be a directory which already exists.
16
18 -e extsize
19 Sets the extent size of the destination realtime file.
20
21 -p Use if the size of the source file is not an even multiple of
22 the block size of the destination filesystem. When -p is speci‐
23 fied xfs_rtcp will pad the destination file to a size which is
24 an even multiple of the filesystem block size. This is neces‐
25 sary since the realtime file is created using direct I/O and the
26 minimum I/O is the filesystem block size.
27
28 -V Prints the version number and exits.

34 Currently, realtime partitions are not supported under the Linux ver‐
35 sion of XFS, and use of a realtime partition WILL CAUSE CORRUPTION on
36 the data partition. As such, this command is made available for curious
37 DEVELOPERS ONLY at this point in time.
