I call it a failure of the layering model. If you want RAID, use MD.
If you want logical volumes, then put LVM on top. Then put

So much simpler...
have you ever replaced a 6 TB drive and waited for the resync of mdadm in the hope in all that hours no other drive goes down?
when your array is 10% used it's braindead
when your array is new and empty it's braindead
ZFS/BTRFS don't neeed to mirror/restore 90% nulls
You cannot consider the amount of data in the
array as parameter for reliability
If the array is 99% full, MD or ZFS/BTRFS have
same behaviour, in terms of reliability.
If the array is 0% full, as well
you completly miss the point!
if your mdadm-array is built with 6 TB drivres wehn you replace a drive
you need to sync 6 TB no matter if 10 MB or 5 TB are actually used
