Hi Srinivas,
Can this patch be combined with the november patches by Andy Yan?
I patched the 2.6.32.2 kernel with patch 1,2,3,4,5,6 (NOT 7) from the
november patches and now if I try to apply this patch it gives numerous
errors.
Do I need to unpatch any of them or can you create a combined patch or is
this already a combined patch including the november patches?
Kind regards,
Caspar Smit

This patch is for a stock 2.6.32.x kernel (at least that's how I tested
it).

(If this tag is valid, couldn't really confirm).
Anyhow, this patch is a huge step up from the stock 2.6.32 kernel, so I'd
like to see this included in the next stable rebuild.

So this patch replaces the november '09 patches?
( [PATCH 7/7]MVSAS: Compatible with the new libsas )
[PATCH 6/7]MVSAS: Enhanced hot plug handling
[PATCH 5/7]MVSAS:Optimization for DMA buffer
[PATCH 4/7]MVSAS:Make code more flexibe for different chip model.
[PATCH 3/7]MVSAS: bug fix with big endian
[PATCH 2/7]MVSAS:add supporting MSI feature
[PATCH 1/7]MVSAS: Update chip initialization
Those patches fixed the raid5/6 initialization issue were disks were
dropped during the creation of a raid set.
Is that fixed in this patch too?

Hi Smit,
This patch can't be combined with the November patch. This patch is based on kernel-2.6.32.7. Yes you need to unpatch all of them and you have to apply freshly.
This is not the combined patch including November patches. My patch addresses the IO issues and tape issues and RAID issues also.
I can't create a combined patch because after applying the November patches I have faced so many issues. I guess PATCH [6/7] is giving problem with November patches.

Hi Smit,
This patch is not exactly replaced with Nov-09 patches.
My patch addresses the RAID5/6 issues also. Below issues are addressed by my patch.
1. Tape issues.
2. RAID-5/6 I/O fails.
3. LVM IO fails and subsequent init 6 hang (connect SAS+SATA in cascaded expanders, crate volume group and logical volumes, run file I/O (alltest), unplug one drive)
4. Disk stress I/O on 4096 sector size.
5. Hot insertion of drives giving panic.
6. 'fdisk -l' hangs with hot plugging of SATA/SAS drives in expander while IO (Diskstress and alltest) is going on and IO stopped.
I can't combined my patch with November-09 patches. James also rejected those patches as those are not proper. Let me know if you have issues with my patch.

I haven't tested yet, but looks like you're doing excellent work, and
your documentation/overview of the work is superb.

Hi Srinivas,
I finally had some time to test your new patch.
1) After numerous hotplug actions with SAS and SATA disks I still can't
get any kernel panic to occur :)
2) I can finally boot a system with 3x 6480 controllers loaded with SATA
disks without a kernel panic.
3) Raid5/6 initialization completes without dropping the disks one after
another.
4) One thing that occured was the following: during a raid1 initialization
of 2 SAS disks and a raid5 init of 8x SSD's i got a call trace by
libata-core.c (see attachment for details). The system continued to work
fine after the trace.
Great work, this is a much more stable driver now!
Kind regards,
Caspar Smit

I have as well. And to sign up for this list. My test setup was admittedly simple, an SFF PC with the SuperMicro AOC-SASLP-MV8 card and two laptop SATA drives from the parts drawer.
I set up two RAID 1 mirrors on the two hard disks; so each disk had two partitions. This was to help locate issues with multiple operations on the same drive.
The mirrors initialized fine, and they ran fine with kernel builds running in each simultaneously. While the mirrors were building, I tried hotplugging and hotunplugging a 3rd disk (on the other SFF connector) several times, and there was no interruption in the mirror progress.
I/O performance looked right in-line for the drives, which admittedly is down in the 45 MB/s range.
I'm also using Fedora 12, which means I took the latest kernel source, applied this patch, then built only mvsas as mv64xx.ko against the 2.6.31 line kernel in Fedora 12. (I stole the name from the binary blob driver SuperMicro has on their "driver CD".)
So, a big "thank you" for the work so far. This weekend, I will install the card in my main server at home (which is Fedora 11) and give it 8 1.5TB SATA disks in mirrored pairs to play with.

Hello,
I have similar findings related to the Srinivas patch.
1) with the patch from Srinivas applied to 2.6.32.7, I cannot get my
raid6 on it's knees (yet). Using 8 drives on the marvell controller, 1
drive on onboard sata_nv .
Created raid6:
mdadm --create /dev/md2 --verbose --level=6 --chunk=1024
--raid-devices=9 /dev/sd[bcdefghij]1
XFS on top
mkfs.xfs -f -d su=1m,sw=7 /dev/md2
During the first raid resync, I'm also dumping 2TB of data on this
11TB xfs volume. It no longer drops drives. Currently copied 1.4T
without glitches.
2) with the patches from Andy Yan applied to 2.6.32.3, the first
resync worked, but when also stressing the system by copying data
during the initial resync, I observed mvs_abort_task which would make
drives kick out of raid after 0.8TB of copying or even quicker.
3) without any patches and a stock Fedora Core 12 kernel, the initial
resync NEVER worked.
So if I can fill my 11TB volume with data, and no drives are ever
kicked out, and xfs does not get corrupt, this patch is a huge
improvement. But this will take some more days to fill up. I'll report
the status when done.
Thanks !

Some good test progress related to mvsas & the Srinivas patch:
I have dumped 10TB of data on a 10.5TB net softraid RAID6 (9x1.5TB)
volume while the initial resync was running. 8 drives were connected
to an mvsas controller, 1 to sata_nv. No XFS corruption, no drives
kicked out of raid. The raid synced without problems.
I'm repeating the experiment with a RAID6 based on 12 1.5T drives: 8
on mvsas, 4 on sata_nv. All of the mvsas attached drives remain
stable. All devices connected to mvsas except for device[4] experience
one of more mvs_I_T_nexus_reset :

This does not seem to affect raid, all drives are still in the set
after 3TB of copying. Are the above warnings something to worry about
?

This is a bit terse for a change like this.

This is the only bit that seems to have a serious technical problem:

It's doing a 100ms CPU spin for each port initialisation. For an eight
port system, that's nearly a second, all of which is done with the
mvi->lock held. In particular, this is done in the ISR on some systems,
so that's really going to add massive delays.
It looks like this is just a bus settle time for the SAS ports, so
obviously they could all be reset in parallel and then the settle time
could be waited out (rather than doing each one in sequence), but
realistically even a single 100ms wait in an interrupt routine is too
long ... the port probably has to be marked as in reset somehow to avoid
this.
Other than the above, there were a large number of checkpatch errors,
which I fixed:
total: 58 errors, 19 warnings, 632 lines checked
can you start with the patch below to carry these fixes forwards?
Thanks,
James

James,
Thanks a lot for reviewing this patch.

I agree with your analysis on the same. Mainly I have added this piece of code for Tape issues. Here I used 100 ms delay which is not required, so I have changed to 10ms i.e mdelay (10). I didn't face any issues with devices after changing it to 10ms.
Please try to include this patch in RC tree. If required I will submit one more patch for the same by considering your suggestion i.e reset in parallel and then the settle time, but this requires a lot of testing to be done so it will take some time to submit the patch.
NOTE: I have attached the patch (copied from below thread) which is having one change i.e mdelay (10).
Thanks,
Srinivas.

This is a bit terse for a change like this.

It's doing a 100ms CPU spin for each port initialisation. For an eight
port system, that's nearly a second, all of which is done with the
mvi->lock held. In particular, this is done in the ISR on some systems,
so that's really going to add massive delays.
It looks like this is just a bus settle time for the SAS ports, so
obviously they could all be reset in parallel and then the settle time
could be waited out (rather than doing each one in sequence), but
realistically even a single 100ms wait in an interrupt routine is too
long ... the port probably has to be marked as in reset somehow to avoid
this.
Other than the above, there were a large number of checkpatch errors,
which I fixed:
total: 58 errors, 19 warnings, 632 lines checked
can you start with the patch below to carry these fixes forwards?
Thanks,
James

I have installed an AOC-SASLP-MV8 on my system (arch linux amd64 2.6.33
with latest mvsas patch from Srinivas). I do not have any mdraid config,
every drive has its own filesystem. Everything works fine, unless i try
to boot with 8 disks. Then booting stalls during the mount disk phase
and eventually i get an "unable to read superblock" message(curiously
fscking all the disks seems to work just before that). When that
happens, the blue activity light for the first drive is constantly on.
This also happened with the stock 2.6.33 kernel.
With 7 or less disks everything works ok, except for this warning that
does not seem to interfere with the operation of the card.

A small correction here, the WD15EADS-00P8B0 drive is not on the
controller but on a motherboard slot, so that explains why smartctl
works without -T permissive. The other 6 drives on the SASLP are Seagate
ST31500541AS and smartctl works without -T permissive for them.

[-- Attachment #1: Type: text/plain, Size: 36201 bytes --]
Hello Srinivas,
I have tested this patch with a stock 2.6.32.7 kernel on a x86_64
running Centos 5.5.
I have another box with 8 1TB disks in a raid6 config: 6 drives are
SAMSUNG HD103SI, 2 drives are Hitachi HDT721010SLA360.
I frequently get the following behaviour:
A large file IO suddenly becomes very slow (eg watching a HDTV file
over samba), then the following is then reported:

Now the disks are never kicked out of raid

sdg1[2] sdf1[1]
5860558848 blocks super 1.2 level 6, 1024k chunk, algorithm 2
[8/8] [UUUUUUUU]
but anything running on this disk is halted and causes time outs. In
the past all these drives were connected to my motherboards SATA ports
as JBOD and they never failed or timed out. When connected to the
Supermicro AOC-SASLP-MV8 using your latest patch with the 10ms delay,
they sometimes timeout, which is difficult to predict.

Hi,
As I didn't have time to give the proper fix for this delay, I have modified to mdelay (10) based on my testing.
With the mdelay (100) every thing is working as expected?
If so I have to modify the code in such a way that it has to reset all the ports in parallel and then the settle time.

Subject: Re: [PATCH] MVSAS: hot plug handling and IO issues
Hello Srinivas,
I have tested this patch with a stock 2.6.32.7 kernel on a x86_64
running Centos 5.5.
I have another box with 8 1TB disks in a raid6 config: 6 drives are
SAMSUNG HD103SI, 2 drives are Hitachi HDT721010SLA360.
I frequently get the following behaviour:
A large file IO suddenly becomes very slow (eg watching a HDTV file
over samba), then the following is then reported:
drivers/scsi/mvsas/mv_sas.c 1631:mvs_query_task:rc= 5

Now the disks are never kicked out of raid
md2 : active raid6 sdl1[7] sde1[0] sdk1[6] sdj1[5] sdi1[4] sdh1[3]
sdg1[2] sdf1[1]
5860558848 blocks super 1.2 level 6, 1024k chunk, algorithm 2
[8/8] [UUUUUUUU]
but anything running on this disk is halted and causes time outs. In
the past all these drives were connected to my motherboards SATA ports
as JBOD and they never failed or timed out. When connected to the
Supermicro AOC-SASLP-MV8 using your latest patch with the 10ms delay,
they sometimes timeout, which is difficult to predict.

Hello Srinivas,
I recompiled your module with the suggested mdelay (100).
I still get lot's of mvs_I_T_nexus_reset errors:
drivers/scsi/mvsas/mv_sas.c 1631:mvs_query_task:rc= 5

The above happened when trying to copy about 200GB of audio backups to
the array, which failed after 19GB. During the copy samba still times
out. When trying to delete the partially copied data directly on the
NAS, it takes ages and similar errors are seen:
[root@nas audio]# du -h -s
19G .
[root@nas audio]# df -H .
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/jumbo-hdtv
6.1T 2.6T 3.5T 44% /mnt/movies
[root@nas audio]# rm -rf *
During the rm -rf, this occurs:
drivers/scsi/mvsas/mv_sas.c 1631:mvs_query_task:rc= 5
drivers/scsi/mvsas/mv_sas.c 1585:mvs_I_T_nexus_reset for device[5]:rc= 0
ata16: translated ATA stat/err 0x01/04 to SCSI SK/ASC/ASCQ 0xb/00/00

ata14: translated ATA stat/err 0x01/04 to SCSI SK/ASC/ASCQ 0xb/00/00
ata14: status=0x01 { Error }
ata14: error=0x04 { DriveStatusError }
and it took ages to complete:
real 6m26.426s
user 0m0.008s
sys 0m0.254s
While this doesn't seem to break any data yet and the 8 drives are
never kicked from raid6, the timeouts and hickups are a serious
problem to data availability.

Hello Srinivas,
I've recompiled kernel 2.6.32.7 on a CentOS 5.5 box using the .config
from /boot/config-2.6.18-164.2.1.el5
- added your patch
- using mdelay (100).
Regarding the previous errors reported: I made the mistake of taking a
working 2.6.32.7 .config which was running fine with your patch on
another Fedora 13 box for some time, and re-using that .config on a
CentOS 5.5 box. Big mistake. The slow deletion is now gone, it seemed
the non mvsas attached disks were also affected.
Now for the first time, I get "Unplug Notice" from mv_sas:

I'm pretty sure these disks are never unplugged as they are hard-wired
in the case and not part of a hotplug backplane.
I've reverted to mdelay (10), but the Unplug notice still occurs, e.g.
when doing a large copy:
drivers/scsi/mvsas/mv_sas.c 1700:<7>mv_abort_task()

So it seems independent of the mdelay value.

Smit,
Thanks for your efforts for verifying the patch.
>>>>>> The disks are detected during boot in reverse order (port 1 -> /dev/sde,port 2 -> /dev/sdd, port 3 -> /dev/sdc, port 4, /dev/sdb) is it possiblewith a simple patch to fix this?
Mostly your HBA is discovering in reverse order. Because we are not facing this kind of problem here. This is specific to your HBA so we should not do changes in driver. Please let me know if you observe any issues with this driver.

libata-core.c (see attachment for details). The system continued to work
fine after the trace.
--
I noticed later that after the above happened, one of my SAS disks was
TERRIBLY slow (5MB/s raid1 sync in stead of 120MB/s) after a reboot all
was fine so it wasn't a defective disk.
Then something else I posted somewhat earlier.
The disks are detected during boot in reverse order (port 1 -> /dev/sde,
port 2 -> /dev/sdd, port 3 -> /dev/sdc, port 4, /dev/sdb) is it possible
with a simple patch to fix this?
Thanks for all your great work!
Kind regards,
Caspar Smit
