Yeah, I have made many mistakes as this is my first time participating
on a mailing list :)
I decided to blow away the filesystem and start over. I did so by
physically removing the new 4 TB drive, mounting -o degraded and then
running:
find . -type f -exec cat {} >> /dev/null \;
In all folders that matter to me to make sure everything is readable
without the new drive. I then formatted the new drive as BTRFS and moved
over all my data. Then I added my old 4 TB drive to the new filesystem
and did balance -dconvert=raid1 -mconvert=raid1. I am now online with
the new filesystem and things are good.
I was expecting btrfs to just work (tm) when adding the new drive and
removing the old, so that made me a little sad. However, it's awesome
that no data was lost and my method actually worked.
Thanks for a great place and product.
