many devices.
The same problem exists for Btrfs subvolumes, and ZFS datasets.
What might be possible and what is definitely not possible, is what
I'm interested in understanding for now.

And what's the implication if the thin volume were to be snapshot?

there's corruption then there's a bug somewhere, adding layers
increases complexity and thus risk. That's possibly a good idea in a
testing/qualification context, where you want something sensitive to
and consistently flags any discrepancy. That's not fragility.

licitly say to
use raid1 over mirror segment type. It doesn't say that about raid0 vs

In that case you might need a delay somewhere to improve the chance
the slow device is discovered. But that's speculation. Really we just
need more information on the storage stack, like a partition by
partition summary. If you get a success

Btrfs supports grow and shrink resizes only when mounted. It's not
possible to resize when unmounted.
