Hi!
I tried to create a snapshot today like this:

The snapshot was not created.
The first time I got this I immediately scrubbed that / filesystem. The
scrub was fine.
I tried doing this snapshot another time after a reboot, to see whether it
happens again. It happened again. And this time the scrub got two errors:

This is on an only about a month old 30 GB Intel mSATA SSDMCEAC030B3 which
reports SMART status as passed and has media wearout indicator still at 100
from 100. So I bet the SSD is still fine.
Will do self-tests tomorrow nonetheless.
I didn´t try this on another BTRFS filesystem and I do not feel comfortable
trying it on /home, although I have a backup from yesterday, but in a different
city :).
I will scrub /home tough, but I bet it is just fine.
I will keep / as is for now. Maybe you have some ideas where I can dig at.
Since this is a production laptop (well, heck, I still test rc1 kernels on
it), I will redo the filesystem if needed for proper operation.
To what I recall snapshots just worked fine with 3.11.
Thanks,
