Bug#714295: linux-image-3.2.0-4-686-pae: ext4 on top of raid1. Frequent and serious data corruption issues
Package: src:linux
Version: 3.2.46-1
Severity: critical
Tags: upstream
Justification: causes serious data loss
Hi,
I'm experiencing frequent data corruption on my raid1 ext4 fs.
The error is not always the same.
I first thought it was due to a previous resize of the FS I've done.
I had multiple times some message about huge amount of multiply claimed blocks in inode xxxx.
fsck.ext4 was not working fully and was always ending with a message like "FS still have error".
I was unable to copy all the files to another FS to save it.
So I end up checking the badblocks (that's where I've been dumb, I choose a non data conservative way).
However, badblock was succesful without errors.
So in the end I lost some data, however, I don't know if it's due to the bug or the the badblocks check. So feel free to readjust severity.
Since theni, I have bought two brand new disks, created a completly new ext4 FS, and copied the files that I had succesfully recovered.
Then I run fsck.ext4 on the FS... it seems it is almost working.
I'm remounting the /dev/md0... And each time I start using the system seriously, I have new errors, like the one I had today:
(I was just copying files on it)
I'm currently going to move the remaining data I have to an ext3 FS.
However I'm leaving my one of my disks as it is so that we can debug it :)
I don't really know if it could be related to https://lkml.org/lkml/2012/10/23/690 or http://www.phoronix.com/scan.php?page=news_item&px=MTIxNDQ.
Let me know how I can help more.
