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

28 xfs(5), mkfs.xfs(8), mount(8).

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