Re: mdadm -> BTRFS conversion

I currently have a pair of external drives configured as ext4 with

filesystems are now BTRFS so I'm looking at converting the external
drives to BTRFS with RAID1. My main reason is to take advantage of
BTRFS checksumming as a guard against bitrot, but I'd also like the
flexibility of setting up subvolumes with different properties (the
disks are currently 90% empty).
Any thoughts on this? What would be the simplest conversion strategy if
I go ahead?
Just a thought.... If the drives are 90% empty and used mainly for backup and there
is sufficient space on the local storage for the remainder I'd take the path of least
resistance.
I'd copy the "non-backedup" stuff to local storage and then blow the rest
away and
create the raid/btrfs volumes from scratch. After that is done, move the stuff back
and do a backup. I'm lazy. And if possible, I'd rather not do something I'm
unlikely to
have to do again in the future. :-) :-)
