Hi,
We are a Channel product team within LSI and we are trying to add Cent OS 5.5 to our compatibility Matrix. We found out that LSI currently has a relationship with CentOS for another project on the Internal Storage division but not with the OS Certification team. We require some information on CentOS which will help us plan the deliverables. And considering the timelines we need to deliver at it will be great if someone from CentOS can help us out in this regard. If anybody else also can answer these in the mailing list, we would be grateful. The questions that we have are as follows:-
1) Cluster Support :
* Does CentOS 5.5 provides native cluster support ?
* Is there any cluster suite available for CentOS 5.5 ?
* Can we use the cluster suite in CentOS 4 for 5.5.
2) Does CentOS have any self Certification tool which allows OEMs/Vendors to qualify the OS and post it in their compatibility matrix?
One we start our qualification, we might need some help in resolving issues/defects on CentOS. Can we open a channel or Point of contact who will be able to help us out with such issues.
I would also request to forward this email to the right forum if the mailing list we are sending to is not the appropriate one.
Thanks and Regards. Kumar Ranjan LSI Technologies.

It's obvious that your research hasn't told you anything about what CentOS is. Via google, and via the website http://www.centos.org/, you can learn that CentOS 5.5 is technically the same as Red Hat Enterprise Linux 5.5. It is the same source code, but compiled by different people, except where branding changes are required, where the source code will be changed to change branding information only.
CentOS 5.5 has the same native cluster support as Red Hat Enterprise Linux 5.5 does.
Is there any cluster suite available for CentOS 5.5 ?
Yes, the Red Hat Cluster Suite is included with CentOS 5.5.
Can we use the cluster suite in CentOS 4 for 5.5.
No.
Does CentOS have any self Certification tool which allows
Not as far as I know, but you should do your own research on this, rather than ask us to do it for you.

CentOS support and engineering channels are described on the CentOS website. But in general CentOS does does not make any technical change in the kernel or clustering software - it is bug for bug compatible with the software produced by Red Hat.
I would also request to forward this email to the right forum if the mailing list we are sending to is not the appropriate one.
No mailing list will do this for you. You need to do your own homework.

What a typical response (on this mailing list). The arrogant and pompous undertones of your email are ridiculous. Heaven forbid a vendor actually try to work with the project to achieve support and compatibility standards.

Don't be foolish with over the top statements....
It takes a trivial bit of time and research to understand the CentOS project guideline of binary compatibility to the Upstream Vendor.
To any technical enough to have such a discussion it should be immediately apparent that 'working with CentOS to deal with bugs for drivers etc' is a pretty pointless statement... and the correct effort is upstream with Redhat.
Should LSI spend the time with Redhat - as they should already be doing quite frankly if they want to be relevant in the linux world - then it assists CentOS automatically.
To be asked to be forwarded to the appropriate forum with zero apparent research in insulting on their part.
The redirection requested was given - and now it is up to LSI to work with Redhat for anything they want certified.

This is far from a "foolish and over the top" statement. It doesn't matter how you think this is logically OK. None of the points you make, be they true or not, are relevant at all. The tone used in the message is the problem, not the facts. If you can't figure out how to talk to other human beings in a reasonable an respectful way, don't say anything at all.

P.S. This stuff *is* on topic because it specifically relates to how the project is run, or at least perceived to be run as users like this are continually allowed to treat others with derision and disrespect.

This response is completely unacceptable. It takes no additional, and actually less, effort to say:
Thanks for your interest but you will have better luck dealing with Redhat directly. This project repackages their software, so if you work with them, any issues you help fix will automatically be applied to CentOS. 2 birds with 1 stone, eh? Pretty nice!
If you can't figure out how to say something in a constructive way, don't say it. Allow others who can, handle it.

I am fairly sure that the CentOS Project does not have any relationship with LSI on any front ( internal storage or otherwise ). We have always encouraged vendors to speak with upstream ( Red Hat ) for things of this nature. However, being a non vendor driven project, there are still some options that you might be able to follow. The most promising one of which is self endorsement.
1)Cluster Support : ·Does CentOS 5.5 provides native cluster support ?
That would depend on what you imply by 'support'. Code components and resources needed to build something of this nature are included into the distribution.
2)Does CentOS have any self Certification tool which allows OEMs/Vendors to qualify the OS and post it in their compatibility matrix?
No. On the other hand, we prefer that vendors do both:
1) Approach upstream for such certifications / testing etc
2) Self endorse CentOS from their perspective with their own toolchains ( which, in your case would be LSI endorsing CentOS as a supported platform ). If there is a reasonable need to do so, we could potentially host a resource that allows third party vendors to document their certification / endorsement; but at the moment there is nothing of that nature on .centos.org
One we start our qualification, we might need some help in resolving issues/defects on CentOS. Can we open a channel or Point of contact who will be able to help us out with such issues.
http://bugs.centos.org/ is the best place to track something of this nature.
Its possible that these things might change in the future, but at the moment this represents the state of play.

MegaCLI is completely unacceptable and the reason why I refuse to buy LSI.
As far as I can tell, the MegaCli package is the way to manage the Dell PERC from the command line in Linux. To work with it you have to hunt down the MegaCli-1.01.39-0.i386.rpm tools since the tools are proprietary to LSI and don't ship with RHEL.
Then you RPM install it and go looking for the software it installed. MegaCli is rarely used. Only when setting up disks. They didn't call it megacli or something I might remember. They called it MegaCli64 (case sensitive) which is installed in /opt/MegaRAID/MegaCli/MegaCli64.
Then you have to figure out how to use it.
# /opt/MegaRAID/MegaCli/MegaCli64 Fatal error - Command Tool invoked with wrong parameters
hmm...ok
# /opt/MegaRAID/MegaCli/MegaCli64 --help Invalid input at or near token -
hmmm
# /opt/MegaRAID/MegaCli/MegaCli64 -h
whoah! This gets you a massive amount of cryptic command line options with no explanation as to their purpose.
This is LSI's idea of "help". I'm a command line commando of 20+ years and this scares even me! It would have been nice if they at least tried to make it work somewhat like the Linux mdadm command or at least provided some examples of common use cases etc. Because of the oddity of this command various people out on the net have compiled "cheat sheets" to help poor souls like me figure out how to use this thing:
http://tools.rapidsoft.de/perc/perc-cheat-sheet.pdf
Usually I avoid using this command and just reboot the server into the BIOS and configure the RAID card from there but often it is not a convenient time for a server reboot. I also avoid it because it is so complicated and one wrong command can lose all of the data in the server. Yes there are backups, which I would really rather not have to restore.
I needed to add a couple of disks on the fly and did not want to reboot. The command line I seemed to need and response it gave me was:
# /opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r0 [32:4] -a0 Adapter 0: Configured the adapter!!
Not a very reassuring response. Configured it how with what? It would be nice if it said "Added virtual disk number 4 as a RAID 0" since that is what that command told it to do.
Using the command:
/opt/MegaRAID/MegaCli/MegaCli -LDInfo -Lall -aALL
I was able to verify that it had in fact created virtual disk number 4 as a RAID 0. However, I didn't have a file to work with in /dev representing the disk. The operating system simply refused to see the disk so that I could actually do something with it. I spent some time trying to figure out why but couldn't come up with a solution. Eventually I just had to reboot and my whole investment in hot-swap chassis and RAID card went out the window.
