Maybe that's what I did to end up with the volume that turned out to be RAID0 for the data. On a whim, even thought btrfs filesystem df /path showed no indications of RAID after adding the second drive, I issued a balance command. I ran 'df' right away and now see the results I don't want -- RAID0 data, RAID1 metadata. Ctrl-C doesn't seem to be aborting the balance. Especially with the currently inflated HDD prices compared to a few months ago, I can't afford to go out and buy an extra drive just to facilitate turning two drives into a mirror. Is there another way? Thanks, James. > > Since I had to get all the data off the volume with the failing drive, > I tried doing the above.
