From mboxrd@z Thu Jan 1 00:00:00 1970 Date: Sun, 5 Sep 1999 09:58:56 +0200 (CEST) From: Rik van Riel Subject: bdflush defaults bugreport Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-linux-mm@kvack.org Return-Path: To: Linux MM List-ID: Hi, yesterday evening I've seen a 32MB machine failing to install because mke2fs was killed due to memory shortage -- memory shortage due to a too large number of dirty blocks (max 40% by default). Lowering the number to 1% solved all problems, so I guess we should lower the number in the kernel to something like 10%, which should be _more_ than enough since the page cache can now be dirty too... Btw, the problem happened on a 2.2.10 machine, so I guess we should lower the 2.2 default as well (to 15%? 20%?). regards, Rik -- The Internet is not a network of computers.
