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

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.

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  curi-
       ous DEVELOPERS ONLY at this point in time.
