From mboxrd@z Thu Jan 1 00:00:00 1970 From: Dmitry Monakhov Subject: [PATCH 6/6] add defragmentation stress test for ext4 Date: Mon, 24 Sep 2012 18:23:21 +0400 Message-ID: <1348496601-32637-6-git-send-email-dmonakhov@openvz.org> References: <1348496601-32637-1-git-send-email-dmonakhov@openvz.org> Cc: xfs@oss.sgi.com, hch@lst.de, Dmitry Monakhov To: linux-ext4@vger.kernel.org, linux-fsdevel@vger.kernel.org Return-path: In-Reply-To: <1348496601-32637-1-git-send-email-dmonakhov@openvz.org> Sender: linux-ext4-owner@vger.kernel.org List-Id: linux-fsdevel.vger.kernel.org Perform various regression tests for ext4defrag subsystem Test1: Defragment file while other task does direct AIO Test2: Perform defragmentation on file under buffered AIO while third task does direct AIO to donor file Test3: Two defrag tasks use common donor file. Test4: Stress defragmentation. Several threads pefrorm fragmentation at random position use inplace=1 will allocate and free blocks inside defrag event improve load pressure. This test known to caught most known e4defrag bugs.
