Package: linux-image-2.6.32-5-amd64
Version: 2.6.32-27
Severity: critical
Tags: upstream
Justification: causes serious data loss

I've got an XFS filesystem on a 28T 12-disk raid6 array:

Personalities : [raid6] [raid5] [raid4] 
md0 : active raid6 sdj1[0] sdi1[11] sdh1[10] sdg1[9] sdf1[8] sdd1[7] sde1[6] sdc1[5] sdb1[4] sdl1[3] sdm1[2] sdk1[1]
      29302638720 blocks super 1.2 level 6, 64k chunk, algorithm 2 [12/12] [UUUUUUUUUUUU]

This is running on a Supermicro X8DT6-F as described below, with a bunch of LSI SAS 2008 cards in the box using the mpt2sas driver. Memory is 24GB ECC registered, tested with memtest86+ extensively. Chassis has dual redundant 1400W power supplies.

Today I ran the following script to attempt to benchmark RAID read and write performance:

#!/bin/bash
for cache_size in 256 512 768 1024 2048 4096 8192 16834 32768; do
 for i in {1..3}; do
 echo ${cache_size} > /sys/block/md0/md/stripe_cache_size
 sync
 echo 3 > /proc/sys/vm/drop_caches
 echo "stripe_cache_size: ${cache_size} (${i}/3)"
 # for write
 dd if=/dev/zero of=/dev/md0 bs=3145728 count=5460
 # for read
 dd if=/dev/md0 of=/dev/null bs=3145728 count=5460
 done
done

as described at http://peterkieser.com/2009/11/29/raid-mdraid-stripe_cache_size-vs-write-transfer/ . Running this script resulted in a number of the following messages appearing in the dmesg log:

After finishing the test, I tried to list the contents of /home (where the filesystem is mounted) with the following result:
ls: reading directory /home: Structure needs cleaning

At this point I realized serious filesystem corruption had occurred. I rebooted the machine and the filesystem did not mount (the following message was in the log):
Dec 22 17:47:09 medusa kernel: [   51.997696] XFS mounting filesystem md0
Dec 22 17:47:09 medusa kernel: [   52.207529] XFS: failed to read root inode

I then ran xfs_repair on the filesystem in question (xfsprogs 3.1.4). I'm sorry, I don't have the log from running it. After this the filesystem mounted cleanly, but instead of 115000 files spanning 2TB, there are 0 files.

I will be checking for hardware faults, but given the absence of any pre-existing problems and the severe nature of the corruption, I would request that this bug report be upstreamed and attempts be made to reproduce this bug given the script above.

Thank you,

David Bronaugh

[...]

This means: write zeroes over the first ~160 MB of the disk.  That will
include filesystem structures.  The kernel does not stop you writing to
a raw device even though there is a filesystem on it.

I suggest you use bonnie++ (packaged in Debian) or iozone (not packaged;
non-free) for I/O benchmarking.

Ben.
