Got this with 4.0.0-rc5 when doing a degraded mount:
Do you get this every time, even after going back to rc4?
Actually, I didn't try yet (going back to 4.0.0-rc4).
Shortly after, it errored with:

After reboot to 4.0.0-rc5, I didn't see "unable to add free space

later.
Do you have messages for the second time it was forced readonly?
