So the story goes like this: i wanted to upgrade my 1TB Disk1 with a new 3TB Disk
1. i replaced the drive
2. i manually formated it in xfs (the entire array was on btrfs the old drive included)
3. i started the rebuild process (now i can't see some of my files)
My question is this, how can i replace the new 3TB drive with the old one (1TB) which has all the original files and create a new parity without losing any data?
