Hi Jeff, et all
I pulled this down last night from
git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev.git
as I don't have an account on master.kernel.org, I assume these are the
same physical tree.
This built fine and seemed aware of all the SATA disks on my controller
(as did previous git branches).
Again using my raid5 (7 disks 1.4tb) example, I am unable to build an
array without the machine hanging.
I am able to access the individual disks for a short period of time
before the box hangs totally which I assume is why the raid array will
not build as the access for the disks hangs, not the actual building of
the array.
I havn't got any output yet on the errors (if there are any) as I left
the array building overnight (300+ minutes) and when I woke up this
morning the box had hung, but power saver had come on the screen so I
couldn't see the messages.
I'll do another test this afternoon and try to get some output for you,
but I just thought I'd let you know this was coming.
Aslo FYI: I'm using maxtor SATA disks, so your patch was of particular
interesting to me.
Many thanks,
Matt

I can now provide further updates for this, although this are not really
super useful.
I've copied the linux-raid list in as well, as after a little more
testing on my part I'd appriciate some input from the raid guys also.
First of all, please ignore the comments above, there was a problem with
grub and it actually "failed back" and booted into the older git
release, so my initial test was actually done running the wrong kenel
which I didn't notice. Appologies to all for this.
Last nights tests where done using the correct kernel (I fixed the grub
typo) 2.6.15-g5367f2d6
The details I have are as follows.
I can run the machine accessing the 7 maxtor SATA disks as individual
disks for around 12 hours now, without any hangs or errors or any real
problems. I've not hit them very hard, but initial performance seems
fine and more than usable.
The actual problems occurr when including these disks in a raid group.

As you can see from my two random disks examples, they are partitioned
and makred as raid auto detect.

I'm getting no on screen messages and the sylog is not reporting anything.
SysRQ is unusable.
I'm open to options on how to resolve this and move the driver forward
(assuming it is the drivers interfaction with the raid sub system)
or
how to get some meaningful debug out to report back to the appropriate
development groups.
thanks.
Matt.

Hello,
I've had a lot of problems with nv_sata (nforce3) and Maxtor harddrives.
Basically it always boils down to :
Dec 24 23:04:34 apollo13 ata3: command 0x35 timeout, stat 0xd0 host_stat
0x21
Dec 24 23:04:34 apollo13 ata3: translated ATA stat/err 0x35/00 to SCSI
SK/ASC/ASCQ 0x4/00/00
Dec 24 23:04:34 apollo13 ata3: status=0x35 { DeviceFault SeekComplete
CorrectedError Error }
Dec 24 23:04:34 apollo13 sd 2:0:0:0: SCSI error: return code = 0x8000002
Dec 24 23:04:34 apollo13 sdc: Current: sense key=0x4
Dec 24 23:04:34 apollo13 ASC=0x0 ASCQ=0x0
Dec 24 23:04:34 apollo13 end_request: I/O error, dev sdc, sector 490223295
Dec 24 23:04:34 apollo13 raid5: Disk failure on sdc1, disabling device.
Operation continuing on 3 devices
Plugging the Maxtor drives on the not-nv SATA sockets solved it (thanks
god I have 2 maxtor and 2 seagate drives)...
If you want more info, just ask.

Thanks for the message,
I'm not using nv_sata, I'm using sata_mv,
just to clarify.
Could we please try to keep this thread on topic.

Matt

Further further information
The speed that the raid array is being built att appears to drop as the
array is created
[=====>...............] recovery = 29.2% (71633360/245111616)
finish=235.1min speed=12296K/sec
[=====>...............] recovery = 29.3% (71874512/245111616)
finish=235.2min speed=12269K/sec
[=====>...............] recovery = 29.4% (72115872/245111616)
finish=236.0min speed=12209K/sec
[=====>...............] recovery = 29.7% (72839648/245111616)
finish=237.4min speed=12091K/sec
[=====>...............] recovery = 29.8% (73078560/245111616)
finish=238.6min speed=12010K/sec
[=====>...............] recovery = 29.8% (73139424/245111616)
finish=350.5min speed=8176K/sec
[=====>...............] recovery = 29.8% (73139424/245111616)
finish=499.6min speed=5735K/sec
[=====>...............] recovery = 29.8% (73139776/245111616)
finish=691.0min speed=4147K/sec
Now the box is hung
I didn't notice this until about %20 through the creation of the array
then I started paying attention to this. These snap shots are taken
every 30 seconds
So the problem appears to sap bandwidth on the card to the point there
the box hangs.
This may have some relevance, or it may not, but worth mentioning at least.
Matt

First - a quick response to John Stoffels comments.
Both disks and controller on the latest Bios/firmware versions (thanks
for making me point this out)
I created a much smaller array (3 disks 1 spare) today and again around
%35 through the creation of the array the whole machine hung, no warning
no errors no logging.
The speed parameter from /proc/mdstat stayed constant to around %30
(which explained why I perhaps didn't notice this earlier) and like the
creation of the large raid 5 array took a massive nose dive in speed
over about 180 seconds to the point where the box hung.
Its almost as if there is an "IO leak" which is the only way I can think
of to describe it.the card / system performaces quite well as individual
disks, but as soon as its entered into a raid 5 configuration using the
any number of disks the creation of the array appears to be fine until
around %20-%30 through the assembly, the speed of the arrays creations
plummits and the machine hangs.
I'm not too sure how to take this further as I get no warnings (other
than the arrays creation time slowing) - I can't use any tools like
netdump or sysRQ.
I'll try some additional raid tests (such as raid0 or raid1 across more
disks) to see how that works. But as it stands I'm not sure how to get
additional information.
thanks,
Matt

You could try and monitor /proc/meminfo and /proc/slabinfo as the system
begins to slow to a crawl, any leaks of io structures should be visible
there as well.

You have 7x250G disks in Raid-5, so that's 6x250G or 1.5T total space.
In the beginning of raid recovery, when the system is good, you're
getting 12M/s. It slows then dies after 25% to 40% of completion.
6x250G is 1536000M, at 12M/s that's about 35 hours. You tested the
disks individually (without Raid) for ~12 hours, which is about 34%
of 35 hours. So it's possible you'd see the the same slowdown & hang
if you tested the individual disks longer.
You're having these problems on a Marvell controller with 2.6.15 and the
in-kernel sata_mv driver, right? I've got a very similar system with
unexplained hard hangs too. On my system the individual disks seem to
work fine, Raid-6 of the disks seems work fine, LVM of the disks seems
to work fine, but LVM of a Raid-6 of the disks hangs.
One wierd thing I've discovered is that if I enable all the kernel
debugging options, the system is perfectly stable, and all the debug
tests report no warnings or errors to the logs. Seems like a race
condition somewhere, I'm suspecting in the interaction of Raid-6 and
LVM, but it could be anywhere I suppose. I've attached the .config of
the production (non-debug) kernel that hangs, and the diff to the debug
kernel that works.

Just to clarify a few things,
using the 2.6.15 kernel I can use and assemble the raid 5 array without
a problem, however using it lvm2 causes it to hang exactly as you have
mentioned before.
When I first started working this problem through I started using some
of he mm patches with the 2.6.15-rc's which made a good difference, in
that I could build and use the array and even with lvm2 for a period of
time, however there was a few quirky bugs with it, in that it couldn't
maintain the arrays stability, on certain occasions, if I rebooted the
box, most of the disks would be marked as unsuable and the array would
refuse to start until it was rebuilt, to futher progress this I started
using the libata git branch which again made things a "little" better,
until the last 2 git versions where I have this problem with the raid
array not being able to build.
from the results I have, have a gut feeling that this is a driver
issue, simpley due to the different results i get with the different
kernels.
I've been given some good thoughts today (last mail in from Mark Haln
has some good suggestions), so all I can do is run the tests Mark
suggested and report back the results to try to progress this forward,
although Marks tests seem to point to hardware issues, such as heat,
vibration etc I still believe this lies at a software driver level, but
its worth running the tests to see what additional data I can get, and
to prove/disprove Marks suggestoins.
I shall report back later
thanks,
Matt

Ok,
reverting back to 2.6.15-rc5-mm3 which was my "good" kernel
I started to rebuild me 3+1 spare raid 5 array (smaller test array) and
it hung on about %50 through
however - from this kernel I got debug results. Bellow (I'll snip them
in future mails)
I'm going to try the same test again with the latest git kernel to see
what happens.
