Hello Friends,

We are using DELL POWEREDGE 6650 Server for our main Database Mysql running on TRUSTIX 2.2 OS.
we have upgraded our RAM from 4GB to 14 GB, Linux recognizes only 4 GB of RAM but it does not recognize the other 10 GB of RAM. The RAM is recognized by the HW through BIOS.

Is there a upgrade patch OS available for huge mem kernel, or we need to recompile the the Kernel.

If yes, any documentation or help is available for that.

Thanks in advance
Sai.

You need the "bigmem" kernel patch. I don't know anything specifically about the "Trustix" distribution, but if you google "bigmem trustix" I suspect you'll be able to find out if there's a prebuilt bigmem kernel for your distribution.

I guess that would depend on if you had a custom rolled kernel. Recompiling seems better since if you haven't..you can strip away things that don't get used.

Hi,
I tried on the internet but did not find any file related to the bigmem-trustix.
Secondly tried installing linux trustix version 3.0 but did not working even with that.
For recompiling we need the package which we are just not able to find on the net any related links also will be of great help.
Thanks,
Sai.

Hello Friends,
I figured it out - had to recompile the kernel with specific options.
Thank you everybody for all the support.
