Hi!
Now I got it myself what I read again and again on this mailinglist: During apt-get upgrade I get no space left on device.
But there is:
merkaba:~> df -hT /

I think I will let it run a rebalance. Not working as well:

How do I get this filesystem to an operational state again despite
reformatting?
Seems there are still no space left on device bugs left. Or some have been
introduced with 3.10.
Thanks,
