https://bugzilla.kernel.org/show_bug.cgi?id=32182 Summary: EXT4-fs error: bad header/extent Product: File System Version: 2.5 Kernel Version: 2.6.38.1 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: ext4 AssignedTo: fs_ext4@xxxxxxxxxxxxxxxxxxxx ReportedBy: ramses.rommel@xxxxxxxxx Regression: No I started noticing ext4-fs errors in my dmesg output, they look like this: EXT4-fs error (device sda2): ext4_ext_check_inode:428: inode #3760218: comm dropbox: bad header/extent: invalid magic - magic 0, entries 0, max 0(0), depth 0(0) EXT4-fs error (device sda2): ext4_ext_check_inode:428: inode #3760208: comm dropbox: bad header/extent: invalid magic - magic 0, entries 0, max 0(0), depth 0(0) EXT4-fs error (device sda2): ext4_ext_check_inode:428: inode #3760218: comm thunderbird-bin: bad header/extent: invalid magic - magic 0, entries 0, max 0(0), depth 0(0) EXT4-fs error (device sda2): ext4_ext_check_inode:428: inode #3760208: comm thunderbird-bin: bad header/extent: invalid magic - magic 0, entries 0, max 0(0), depth 0(0) I fsck'ed the partition which showed nothing but the regular output but said the file system was modified, after a reboot the same errors returned though. I'm using e2fsprogs 1.41.14 and linux 2.6.38.1 and after a downgrade to linux 2.6.37.5 the errors kept reappearing (I'll test 2.6.38.2 soon but I didn't find commit messages that seemed relevant). I ran debugfs on one of the inodes: % debugfs -R 'stat <3760208>' /dev/disk/by-label/home debugfs 1.41.14 (22-Dec-2010) Inode: 3760208 Type: regular Mode: 0644 Flags: 0x80000 Generation: 231468018 Version: 0x00000001 User: 1000 Group: 100 Size: 42 File ACL: 0 Directory ACL: 0 Links: 1 Blockcount: 0 Fragment: Address: 0 Number: 0 Size: 0 ctime: 0x4b2a09ff -- Thu Dec 17 11:37:51 2009 atime: 0x4d909367 -- Mon Mar 28 15:55:51 2011 mtime: 0x490976f8 -- Thu Oct 30 09:57:28 2008 EXTENTS: I'm not sure what extra info to give you, but I'd be glad to provide stuff you need to reproduce/fix this. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
