Topic: My SME server 7.4 do not recognize more than 4GB of ram in my server

[veebr0]

Hi guys, today I finally install my IBM X3650 server  with 12GB of ram,  but when I ron the free command I can see that only 4 GB of ran has been recognized event 12GB that I had installed in this Server, really need that the server recognized all of physically memory due to I have to user VMware to create a Virtual Windows 2003 server r2.

[root@serverfp ~]# free

SME Server is not 64 bit so it is not possible to see all 12GB.
Here is my recommendation.

Install CentOS 64-bit on your server (usually designated by x86_64 or AMD64), then install VMWare on that, and finally install SME in a virtual machine.
It may not be pretty but it is the only way to utilize all 12GB of RAM in your server.

this is not true.. please read here.. you need a different kernel

I only meant that the default SME install is not 64 bit.
That looks like it will work well, except that you would have to manually set it up if its not available in any repos.

I don't think that is what Stefano meant. SME normally has smp as a kernel option which will give you 16GB addressable. You should only have to do something "unnatural" if you need more than that (going to hugemem). I personally run 8GB and have VMWare on top of SME.

When the system boots up you will be given an option as to running EL or ELsmp. If you run a single proc then you may have to take additional steps to boot with the smp kernel. I'm sure a check through the wiki will get you what you need.

No, there is nothing special to do, just choose ELsmp from the menu, using arrow keys.
Once the SMP kernel is chosen, it will be the default at next reboot.

"SME server 7.4 do not recognize more than 4GB of ram" sounds like a problem to me.

I wasn't sure because in my quick search I found:
http://bugs.contribs.org/show_bug.cgi?id=3095
which let to FAQ entry:
http://wiki.contribs.org/SME_Server:Documentation:FAQ#Booting_with_SMP_kernel_after_upgrade_to_version_7.2_from_CD

which seem to indicate uniproc's may require you to install ELsmp explicitly for an upgrade (with resolution to the bug in SME8 timeframe). But I wasn't sure if a fresh install would see the same issue given the problem description in 3095.

Yes. I'd forgotten about that bug (which should never have been allowed to creep in).

Hey, In this opportunity I want to say Thanks  to all, but specially to Craig, Stefano and Christian due to the information provided was very interesting, however as I said before I´m not an expert in SME  now,  I hope in the future will be  , really Cristian I don't understand when you say that "there is nothing special to do, just choose ELsmp from the menu, using arrow keys" where I found this option when the SME server is booting or when I'm installing it.

I really appreciate your answer or necessary clear steps to find a fine solution to my problem.

Actually Charlie said that but what I said was:

When the system boots up you will be given an option as to running EL or ELsmp.

So boot, and you will be given the choice (for about 5 seconds before it chooses the default); use the arrow keys to choose the kernel you want. Charlie then further clarified that once you choose this option, it will be saved as the default kernel for booting.

If when you boot you only see an option for EL and ELsmp does not exist then take a look at the FAQ entry I refer to above (http://wiki.contribs.org/SME_Server:Documentation:FAQ#Booting_with_SMP_kernel_after_upgrade_to_version_7.2_from_CD).
It will tell you how to update to ELsmp.

Hope that helps.

Thanks Charlie for your advise, I will consider your recommendation for futures questions, however the ELsmp module was available in the boot option, so now I can see 12GB ram and all server procesor installed in my server (4), but for culture and learning more what ELsmp mean, can some one explain me or sent a link page that I can red.

Thanks to all

Have you done an advanced search on these forums as I'm certain that question has been answered here previously. Go back a year or two or three though.

Even google should give you the answer.
