From mboxrd@z Thu Jan 1 00:00:00 1970 From: Josef Bacik Subject: [PATCH] Btrfs: fix chunk allocate size calculation Date: Wed, 17 Mar 2010 16:45:56 -0400 Message-ID: <20100317204556.GA4409@localhost.localdomain> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii To: linux-btrfs@vger.kernel.org Return-path: List-ID: If the amount of free space left in a device is less than what we think should be the minimum size, just ignore the minimum size and use the amount we have. I ran into this running tests on a 600mb volume, the chunk allocator wouldn't let me allocate the last 52mb of the disk for data because we want to have at least 64mb chunks for data. This patch fixes that problem.
