Subject: ENOSPC with 270GiB free
Date: Sun, 16 Feb 2014 14:58:08 +0100	[thread overview]
Message-ID: <20140216135808.GA1491@frosties> (raw)

Hi,

I'm getting a ENOSPC error from btrfs despite there still being plenty
of space left:

% df -m /mnt/nas3
Filesystem         1M-blocks     Used Available Use% Mounted on
/dev/mapper/nas3-a  19077220 18805132    270773  99% /mnt/nas3

% btrfs fi show
Label: none  uuid: 4b18f84e-2499-41ca-81ff-fe1783c11491
        Total devices 1 FS bytes used 17.91TiB
        devid    1 size 18.19TiB used 17.94TiB path /dev/mapper/nas3-a

Btrfs v3.12

% btrfs fi df
Data, single: total=17.89TiB, used=17.88TiB
System, DUP: total=32.00MiB, used=1.92MiB
Metadata, DUP: total=25.50GiB, used=24.89GiB

As you can see there are still 270GiB free and plenty of block groups
free on the device too.

So why isn't btrfs allocating a new block group to store more data?

MfG
	Goswin
