How do you read this then:

Label: none uuid: 27fafa43-7ad0-4e8a-ada8-36f73ef8984c
Total devices 2 FS bytes used 79.63GB
devid 2 size 111.79GB used 111.01GB path /dev/sdb
devid 1 size 111.79GB used 111.03GB path /dev/sda

I'm pretty sure I created this fs with -d raid1 -m raid1! Speaking
of which, is there a way to read a FS configuration: how can I tell
this FS really uses raid1 for both data and metadata?

The used column is surprising: if it's a mirror why 111.01 and
111.03? And why all the space is being used anyway: I mean what's
the difference between the 79.63GB and 111.0[13]?

And the output of df is confusing too:
/dev/sdb 234441648 83501968 150939680 36% /space

It's reporting twice the total space but I think I remember looking
it up and that should be fixed in a future kernel version.
