Unfortunately, using cp or rsync is not possible because the
filesystem has a real-time device attached to it. It's basically a
~10GB data device and a ~500GB real-time device. I'd say it's from a
DVR or something like that, and that Jeffrey is trying to put
a bigger disk in the DVR....
Hence there are various DVR forums that suggest xfsdump/xfsrestore
is the best method for copying such filesystems to a larger disk.
I'd guess that people haven't found xfs_rtcp, or maybe they saw the
caveat in the man page(*) and didn't use it....
Cheers,
Dave.
(*) CAVEATS
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 ONLY at this
point in time.
