Bug ID: 187051
Summary: "orphan list check failed" error in ext4
Product: File System
Version: 2.5
Kernel Version: 4.8.6
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: ext4
Assignee: fs_ext4@kernel-bugs.osdl.org
Reporter: me@hussam.eu.org
Regression: No
I saw a ext4 "orphan list check failed" in my logs. It is happening on a new
1TB hard disk and mostly when idle.
I did a smart check and a a fsck check for bad sectors from the arch linux
rescue usb. neither saw anything.
I formatted the disk again and restored a backup. Then I thought I would just
get a replacement instead of wait for this to happen again.
Same issue happened 50 minutes ago.
"Filesystem features: has_journal ext_attr resize_inode dir_index filetype
needs_recovery extent 64bit flex_bg sparse_super large_file huge_file dir_nlink
extra_isize metadata_csum".
and formatted under kernel 4.8 with latest e2fsprogs.
Checking the inode that caused the hiccup reveals it points to a folder in
/usr/share/ that was not touched since the 25th of last month and I have fscked
and rebooted plenty of times since then. I fsck on each reboot anyway.
I did a fsck -D -fv /dev/mapper/root from rescue usb after last reboot too.
Could the metadata_csum option be causing this? the kernel.org ext4 wiki
suggested it is a integrity measure.
My backups don't include system journals to save space on backup media so I
don't have the full kernel crash log.
I am sure there was no I/O error message in the crash log when I typed dmesg
and I was told on arch linux logs that this rules out any hardware errors.
I believe this is the second time this has happened.
