Hi, all --
It's long past time

to upgrade diskfarm. It is also, coincidentally, time to add a mirror drive, which of course one can't do on the running system. Soooo ...
Actually with btrfs (which is default on openSUSE) you can replace drive with different drive, effectively moving filesystem content to different drive, online
Can I *upgrade* my system to another partition, like one on the new mirror? Or how (rsync? cp -a? cpio? tar? ...) can I copy the old partition content to a new slice of slightly different size (around the RAID metadata) to then boot from it instead, and then update? [I actually have two identical slices on the drive and use dd to copy over as a backup before upgrading, but dd won't work here.]
I am, of course, seeking the simplicity of an upgrade while retaining the security of falling back to the old installation if needed, all in the same timeframe as adding the mirror because, well, duh :-)
TIA & HAND
