Hello,
I've been running a 12 disk raid6 setup with cheap 1.5 TB green drives
(western digital and seagate lp) across one 8 port mvsas supermicro
controller and 4 ports of the onboard sata_nv of an Asus K8NE4 deluxe
motherboard for about a year. This setup has been very stable until
recently one of the attached western digital disks started giving
uncorrectable offline errors, which was replaced under warranty by a
new seagate disk.
Recently, for some unknown reason the whole supermicro controller
starts to fail at once under load, and drops all 8 attached disks out
of raid:
# cat /proc/mdstat
Personalities : [raid6] [raid5] [raid4]
md2 : active raid6 sdb1[0](F) sdm1[11] sdl1[10] sdj1[16] sdk1[13]
sdi1[14](F) sdh1[12](F) sdg1[5](F) sdf1[15](F) sde1[3](F) sdd1[2](F)
sdc1[1](F)
14651351040 blocks super 1.2 level 6, 1024k chunk, algorithm 2
[12/4] [________UUUU]
unused devices: <none>
This appears when md2 is under load, e.g. defragmenting the xfs
filesystem on top of the raid, or when raid is rebuilding.
I can recover the raid by rebooting and forcing mdadm:
mdadm -A /dev/md2 -f /dev/sd[b-m]1
but I suspect my raid6 consistency is going to break once if this
problem keeps repeating.

The "no sig fis" keeps on repeating in the dmesg.
Kernel is Linux hd 2.6.37-rc4 #1 SMP Fri Dec 3 11:53:33 CET 2010
x86_64 x86_64 x86_64 GNU/Linux
This setup has been stable for about one year, with lot's of IO and
nightly defragmenting the xfs filesystem.
Is my controller dying (=dropping all 8 connected disks) or is this a
known bug ?
I have a second system with the same controller and a smaller raid6
set of just 8 1TB disks, but this will take some time swapping both
controllers and cabling to eliminate a bad controller.
Best regards,
Frederic Vanden Poel
