There should be no problem using dd to move a LVM volume to a raid volume or anything else. Basically, somewhere you have a block device (the thing you created your filesystem on). Just dd that to your new block device and you are done. Or, an easier point, whatever you pass in the <HERE> is your old block device: mount <HERE> /var/lib/backuppc Sure, it is all confusing as hell, until you remember that you simply want to copy whatever the FS level is looking at, and your destination device is again some raid/LVM/loopback file/whatever "block device". If your source "device" is equal or smaller than the destination device, and it is feasible to copy the entire data from the source to the destination, then dd is the perfect tool, and this is the ideal solution to the problem of moving the pool. The only reasons why you would not use it: 1) You can't physically connect that many HDD's at the same time to the same machine 2) The source and destination are far away (ie, slow network connection between them) 3) The destination is too small (should you really be doing this anyway?) 4) You want to use a different filesystem format on the destination 5) The source and destination are actually the same device, you just want to re-arrange them (eg, migrate from LVM to md or similar). 6) Probably some others, but by now, you should realise that dd is probably the ideal tool for the job, and you should go ahead and make use of it. Personally, I would use my filesystem fsck and force a check afterward just to make myself sleep a little better at night. I hope someone works out a way to add the above to the wiki, in a more meaningful/less wordy way.
