Thomas,

The patches you are using are the ones from november '09 i presume?
Those
patches still had a lot of SATA issues so I think they didn't make the
kernel. The patches seemed to handle SAS disks just fine though. SATA
disks was a whole different story.

I'm actually using some that Andy Yan sent me privately, I'm not sure
if they are the same exact ones he sent to linux-scsi. Probably are
though.

The november patches were a set of 7 patches where only the first 6
needed to be applied.

Yeah, I was given a zip of the driver a little while before he posted the 
patches to the list.

Srinivas Naga Venkatasatya Pasagadugula created a patch instead of
Andy Yan's patches which seemed to handle SATA disks a lot better but
still after some tests it had alot of problems. Srinivas Naga
Venkatasatya Pasagadugula is now in the process of creating a new
patch to fix the remaining issues. He told me it would take a long
time to create those and
it is now a few months ago since. I and others submitted extensive
logging
for him to check.

As for production I could only advise this:

Using SAS disks: Use stock 2.6.34 kernel + Andy Yan's patches
Using SATA disks: DO NOT GO INTO PRODCUTION.

I've been using the code Andy Yan sent me for 7 months now with 5 SATA
disks
on a md raid5 array. I haven't noticed anything serious in that time.
Prior
to tonight I had been using 2.6.32 for quite some time.

Maybe the issues only show up with serious load? My raid array doesn't
get hammered, at least not often.

The main problem was hotplugging a SATA disk. This results in a kernel
panic almost all of the time. There were more issues like the
HDIO_GET_IDENTITY failed messages during boot for SATA disks and VERY
SLOW xfs creation times.

I don't recall xfs taking /that/ long for a 4TB fs. With 2.6.34 I don't see 
any HDIO_GET_IDENTITY messages in dmesg. But I'll bet it freaks out if I try 
and hot remove one of the drives. I remember seeing the card lockup, and/or 
the kernel oopsing the last time I tried (2.6.30-2.6.32 time frame). 
Thankfully its not something I often do. While I Can, since I have a hot 
swap unit, its just not something I've had to do yet.

This array has been pretty solid for the past 6 months. Not sure it helps 
but I've been very careful with this machine, it gets shut down 
automatically and safely when the UPS battery gets low, so there hasn't been 
any abrupt shutdowns, except today when a forkbomb hit, and I had to 
SYSRQ+S+U+B the box.

At any rate I can help test whatever new patches might come along.

Kind regards,
Caspar Smit
