Description nickcheng 2007-03-22 00:28:38 EDT
Description of problem:
Please help Areca SAS/SATA-RAID driver backport to RHEL4.
Comment 1 nickcheng 2007-03-23 01:43:13 EDT
This bug is dependent on "Bugzilla Bug 233056: Add support for Areca RAID
controllers (include arcmsr driver from 2.6.19) "
Please refer to it.
Thanks,
Comment 2 Andrius Benokraitis 2007-03-23 03:06:15 EDT
Bug 205897 is also dependent on this bug, since RHEL 5.1 is slated to be in
development before RHEL 4.6.
Comment 3 Tom Coughlan 2007-04-26 12:18:19 EDT
Backporting this driver to the 2.6.9 kernel may require some significant effort.
There will also be on-going support costs for this in RHEL 4. I do not believe
we currently have the business case to justify that cost and effort. Customers
who want to run this adapter will be able to move to RHEL 5 to get support for it. 
Comment 4 Nick Cheng 2007-04-26 21:56:22 EDT
Tom
Actually we still have a lot of customers whom got business on NAS system that
is based on kernel 2.6.9-xx.
It will cost them a lot of time if moving to latter kernel version.
I still not hear they would invest in that.
The request for the driver disk still remains.
Sincerely hope Redhat could take it into consideration. 
Comment 5 Jan Iven 2007-05-14 10:58:57 EDT
Customers (i.e. us) really would like this (see e.g. our IT#79615) even on
RHEL4. Please consider reopening.
Comment 6 dijuremo 2007-05-14 11:23:16 EDT
RHEL4 still has about 5 years of life (based on the 7 year lifespan for each
version of RHEL, right?) so adding it to the release kernel in future RHEL4
updates would really simplify the lives of many sysadmins who have to manually
compile and add the module each time the kernel is updated.  

I would also like to ask you to reconsider adding it to a future RHEL4 update.
Comment 8 dijuremo 2007-05-15 11:33:58 EDT
Nick,

Can you confirm if the patch for RHEL4 would be identical to the one you
submitted for RHEL5? I believe the driver code is the same, so there would not
be any extra effort needed to maintain two separate patches, but I have not
studied the complete source code for the areca driver, I still believe it is
very similar if not identical.

Is anyone from Red Hat considering looking at reopening this request?

Comment 9 nickcheng 2007-05-15 23:42:02 EDT
Diego,
They are very similar, but a little bit diffenert.
I will make time to build the patch these days.

The patch for Areca driver, arcmsr-1.20.00.13, in RHEL4
Comment 12 nickcheng 2007-05-21 03:56:45 EDT
Hi Tom,
Are there anybody in charge of this project?
Actually there are still a lot of customers running on RHEL4.
Comment 13 Tom Coughlan 2007-05-31 10:21:24 EDT
Okay, okay... I see there is plenty of interest in this for RHEL 4. I will
re-open this, and we will attempt to get it done in 4.6. If there are any
glitches whatsoever, in either 5.1 or 4.6, then we may need to defer this until
after 4.6. 
Comment 14 RHEL Product and Program Management 2007-05-31 10:24:56 EDT
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release.  Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products.  This request is not yet committed for inclusion in an Update
release.
Comment 15 Tomas Henzl 2007-06-04 04:50:42 EDT
Nick,

please could you specify on which RHEL architectures Areca
has tested and will support this driver ? 
I expect that as for 5.1 it will be the x86_64, i686 and PowerPC.

Tomas


Comment 16 nickcheng 2007-06-04 05:35:03 EDT
Yes,
It is the same with the driver in RHEL5, i.e. x86_64、i686、Sparc、Sparc64、PowerPC.
Comment 17 Baif 2007-06-04 12:40:24 EDT
Hi. I had test the arcmsr.1.20.0X.13 ,arcmsr.1.20.0X.14 on "RHEL 4 update 4, 
update 5, x86_64) with SMP kernel, 4GB memory or more, onn Intel XEN platform 
with EM64T and Hyper-Threading.

Looping with CLI V1.72.250_70306 or the API call to 
ArcLib(Arclib_Build250_70306) will cause memory exhausted and unload the 
arcmsr module would NOT free the memory had been "used". 

Hank from Areca Inc. had confirmed that, and he said:
"the problem was gone when using the kernel 2.6.18 even the memory size > 4G 
and intel platform". And he "guess this may the bug of kernel of 2.6.9 on 
intel platform".

But I think that would be some bugs in arcmsr.1.20.0X.13 or arcmsr.1.20.0X.14.
SO where are the bugs?


The Makefile for compiling outside the kernel source tree hand been tested:
==========================================
obj-m := arcmsr.o
KDIR := /lib/modules/$(shell uname -r)/build
PWD := $(shell pwd)
default:
$(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules
==========================================
Comment 18 Baif 2007-06-05 00:14:20 EDT
The problem will not happen on AMD platform. RHEL 4 update 4, update 5 SMP 
with 8GB memory had been done and the problem did NOT come up.
Comment 19 Tomas Henzl 2007-06-05 08:51:33 EDT
Nick,
please take a look at the memory error. 
Thanks Tomas
Comment 20 nickcheng 2007-06-05 08:55:04 EDT
Yes, we have post a patch to the customer.
Actually it doesn't come up in the version that we post to RedHat.
Comment 22 RHEL Product and Program Management 2007-06-19 08:54:12 EDT
This request was evaluated by Red Hat Kernel Team for inclusion in a Red
Hat Enterprise Linux maintenance release, and has moved to bugzilla 
status POST.
Comment 23 nickcheng 2007-07-02 22:05:14 EDT
Hi guys,
I heard RH complains Areca delays the process.
Is it true?
If yes, please let me know where.
Comment 24 Andrius Benokraitis 2007-07-05 15:41:07 EDT
Nick - Can you be more specific? AFAIK, there are no items waiting on Areca
until the driver is added to RHEL 4.6.
Comment 25 nickcheng 2007-07-05 21:33:56 EDT
An important customer in Euro stated that a PM in RH argued Areca slowd the
certification process.
I thought the process came along quite well and I am bewildered by the compliant.   
Therefore I have to inquire the reason why it happened.
I will pass your message to our customer.
Thanks,
Comment 26 Andrius Benokraitis 2007-07-05 23:31:50 EDT
Nick, if you have the name of the Red Hatter you can pass on to me, that would
be great. I am also bewildered as well, since there is no official
"certification" per se on hardware devices or peripherals. This is the first
I've heard of any dissatisfaction on the current strides to include the Areca
driver after formalizing the relationship. Obviously there has been some
clamoring to have the driver included in RHEL, but it was only included into
Fedora recently.
Comment 27 Tomas Henzl 2007-07-06 04:23:30 EDT
Nick, I haven't heard about this, and as for me I'm not complaining.
Comment 29 Jason Baron 2007-07-31 11:49:06 EDT
committed in stream U6 build 55.26. A test kernel with this patch is available

Comment 33 nickcheng 2007-09-05 21:47:26 EDT
John,
I cann't get access to the RHEL4 Update 6 x86_64 Beta disk4 from last week. But
there are no problem with other disks 
I retried it for many many times but it always repried with no cache on my FlashGet.
Would you please check it out?
Comment 34 Andrius Benokraitis 2007-09-05 22:41:12 EDT
Nick - did you try the most recent snapshot released today?
Comment 35 Jay Turner 2007-09-07 08:20:15 EDT
Were you attempting to download the Snapshot 1 images?  And which variant
specifically (AS, ES, WS, Desktop) are you seeing problems with?
Comment 36 nickcheng 2007-09-07 08:50:30 EDT
I have downloaded the ISO from
ftp://partners.redhat.com/797f57b13f1626c5e26da50bd1f52300/, which Andrius give
it to me today.
I will test ES variant next Monday.
Comment 37 Nick Cheng 2007-09-10 21:43:59 EDT
We have tested ES x86_64 version yesterday.
It looks good so far.
