From: "Subranshu Patel - ERS, HCL Tech" Subject: df command on EXT4 and XFS filesystem Date: Thu, 7 Feb 2013 12:18:26 +0530 Message-ID: <60A0C755EDF2954AA9C18966C50DB31429E2A0A49C@NDA-HCLT-EVS05.HCLT.CORP.HCL.IN> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 8BIT To: "linux-ext4@vger.kernel.org" Return-path: Received: from gws05.hcl.com ([203.105.185.23]:35871 "EHLO gws05.hcl.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751714Ab3BGG6Y convert rfc822-to-8bit (ORCPT ); Thu, 7 Feb 2013 01:58:24 -0500 Content-Language: en-US Sender: linux-ext4-owner@vger.kernel.org List-ID: I have an observation on EXT4 filesystem. I created filesystem of size 1TB, 4TB, and 7TB and then checked the output of df command. df command showed the number of 1KB blocks used. The result was: 1TB: 204056 4TB: 198680 7TB: 181784 This trend was surprising, with increasing filesystem size, the number of used blocks decreased.
