Gotcha, thanks for confirming, so -m raid1 -d raid0 really only protects

Netgear uses BTRFS as the filesystem in their refreshed ReadyNAS line.
They apparently use Oracle's linux distro so I assume they're relying on

Hi Hugo,
Thanks for your answer.
Unfortunately, I had also tried
sudo mount -o degraded /dev/sdc1 /samples
mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
missing codepage or helper program, or other error
In some cases

Did the crashed /dev/sdb have more than 1 partitions in your raid1

No, only 1 - as far as I recall.

What does:
btrfs filesystem df /samples
say now that you've mounted the fs readonly?

you did read off is correct. :)
Of course, I still can't add my new /dev/sdb to /samples because it's
read-only:
sudo btrfs device add /dev/sdb /samples
ERROR: error adding the device '/dev/sdb' - Read-only file system

Yes - I know. But btrfs promises that I can add bigger disks and

There's no mystery here, you're simply out of space.
Except the mystery that I had to expand the filesystem to something
between 20GB and 50GB in order to complete the operation

What's mysterious about needing to grow the filesystem to over 20GB to
unpack 10MB of (small, so yes, many) files?
When you shrink it btrfs is going to throw
