Subject: [Bug 114821] New: Frequent and recurring ext4 "bad header invalid magic" errors on a healthy drive
Date: Thu, 17 Mar 2016 05:05:04 +0000 [thread overview]
Message-ID: <bug-114821-13602@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=114821
Bug ID: 114821
Summary: Frequent and recurring ext4 "bad header invalid magic"
errors on a healthy drive
Product: File System
Version: 2.5
Kernel Version: 3.18.5+
Hardware: ARM
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: ext4
Assignee: fs_ext4@kernel-bugs.osdl.org
Reporter: dse.ssd@gmail.com
Regression: No
Recurring ext4 "bad header" errors are reported for a healthy, few months old
external USB drive (WD MyBook 1230) connected to a Raspberry Pi running
Raspbian 7, kernel 3.18.5+. The drive was working fine previously when
formatted in NTFS, SMART has no errors logged, drive passes short and long
SMART self-tests as well as manufacturer diagnostic tests (WD Data Lifeguard).
Another external USB drive (a WD MyBook 1140), formatted in NTFS shows no
problems when connected to the same machine. The specific error is:
ext4_ext_check_inode:495: inode #1523: comm ls: pblk 0 bad header/extent:
invalid magic - magic 0, entries 0, max 0(0), depth 0(0)
The errors are produced whenever some certain files are accessed and the hard
drive produces a distinct (and rather unsettling) clunk every few seconds,
which sounds like a head load/unload or something, but the files seem to be
read without error.
Running fsck reports and fixes some errors and makes the ext4 partition clean
again, but the same errors are produced when the files are read again. The
offending files can be moved to another device and back to the same location to
stop the error from recurring, but it soon appears when accessing other files.
