xfs_rtcp - XFS realtime copy command
[ -e extsize
] [ -p
copies a file to the realtime partition on an XFS filesystem. If
there is more than one source
, the final argument
) must be a directory which already exists.
- -e extsize
- Sets the extent size of the destination realtime file.
- 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.
- Prints the version number and exits.
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
at this point in time.
