Hi, Perhaps not *completely* unrelated, but anyway... I have an MD RAID1 over two disks - works just fine. This provides some protection against disk failure. I am now wondering about protection against stupidity such as 'rm -rf; oops'. I'm going to ignore other risks (eg fire) for now. In this vain, I've bought an external 500GB USB/FW drive and I plan to use rdiff-backup <http://www.nongnu.org/rdiff-backup/> to back up the contents of the RAID1 to that. I think this buys me some protection. My question is - what is the best way to ensure that, in future, I can easily expand the filesystem on the external drive, so that it is transparent to the host and doesn't require any copying/etc? My first thoughts (from experience on MythTv) go to logical volumes - is this what I should be looking at?
