From: Jan Engelhardt Subject: mkfs.ext4: high default -i value undocumented Date: Wed, 4 Mar 2009 00:12:50 +0100 (CET) Message-ID: Mime-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Cc: kzak@redhat.com To: linux-ext4@vger.kernel.org Return-path: Received: from sovereign.computergmbh.de ([85.214.69.204]:43486 "EHLO sovereign.computergmbh.de" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1753285AbZCCXMx (ORCPT ); Tue, 3 Mar 2009 18:12:53 -0500 Sender: linux-ext4-owner@vger.kernel.org List-ID: Hi, Creating an ext4 filesystem on a 4 GB image file (to be loop-mounted later) gives me 256K inodes. Choosing -i 4096 instead gives 1M, which would mean the default for -i is 16384. Besides me finding 16384 a little unreasonable (XFS offers 2M inodes by default), the big point is that the mke2fs manpage (belonging to util-linux, hence Cc) does not mention this 16384 default. Hope this can be addressed. # rpm -q e2fsprogs util-linux e2fsprogs-1.41.4-2.2 util-linux-2.14.2-2.2 Jan
