Subject: Re: BTRFS constantly reports "No space left on device" even with a huge unallocated space
Date: Mon, 22 Aug 2016 16:11:31 -0300	[thread overview]
Message-ID: <1471893091.3385.5.camel@gmail.com> (raw)
In-Reply-To: <CAJCQCtTrGTjOMaNNV7JKBybgbyn=_pYP=KvE1zc4AuPs=mo2=A@mail.gmail.com>

New information guys! I formatted using the latest Tumbleweed snapshot
(btrfs-progs v4.7+20160729) and I still have the same problem.

I notice two things. First, when I see the "No space left on device",
it is fixed when the Metadata space increases **a lot**. For example,
when the error first occurred, I had:

Metadata, DUP: total=2.00GiB, used=811.52MiB

After waiting a while (could not run balance), it was automatically
fixed and then I have:

Metadata, DUP: total=9.50GiB, used=811.52MiB

During the error, when I ran the balance command, I see these messages
in `dmesg`:

Does it add anything relevant to the problem?
