From 0fab0a4afdff2f27fce49e7b38179e781e7b64ed Mon Sep 17 00:00:00 2001 From: Peter Korsgaard Date: Fri, 12 Apr 2013 14:57:36 +0200 Subject: [PATCH] fs/ext2: bump journal overhead to 1300 blocks A quick test with a ~3.5MB ext4 filesystem shows that 1081 blocks isn't enough: tune2fs 1.42.7 (21-Jan-2013) Please run e2fsck on the filesystem. Creating journal inode: Journal size too big for filesystem. So bump it a bit. Overestimating the journal size is probably not really a big deal for the kind of systems using ext3/4 anyway.
