similar to: How to check server kernel support 32 Gb RAM (X86,

we have CENTOS 4.7 (X86) on DELL server, I already put 32 GB RAM on it. I can use "top" or "free" to check memory and it did show 32 GB. I check REDHAT site and found it say: The "SMP" kernel supports a maximum of 16GB of main memory. Systems with more than 16GB of main memory use the "Hugemem" kernel. I use "uname -r" to check kernel and it

I am building a new system which will have a pair of dual-core Opterons and 16GB memory. Should I use kernel-smp or kernel-hugemem? I see that RH recommends the hugemem kernel if you have more than 16GB (and we may upgrade at some point, the MB supports 32GB). Any comments on this? The only difference that the descriptions show is the 4GB/4GB split with the hugemem kernel and I'm not quite

Is this a known bug? Suprisingly google didn't turn up much. I'm running DDR RAM and a AMD XP processor on CentOS 4.

greetings how about some more of that practical CentOS stuff like amount of RAM vrs specific kernel info... im sure it is in a doc somewhere yet can someone enlighten... in all cases running latest" CentOS 4.... and since we all know when we have more than one processor, it is easy to choose SMP or not... and most of us can tell if we are i386, i586, i686, AMD whatever, Opteron etc...

There was a discussion here several days ago that was precipitated by my decision to manually install the new kernel before YUMming the upgrade to CentOS 4.2. The upgrade went south but I recovered by doing a fresh install and a bunch of copying from backups. All's well EXCEPT that I'm back in the same "box", thanks to anaconda. I set out to upgrade kernels this morning:

I am changing a system from zap to DAHDI. I removed everything zap. when doing the command: sh -x /etc/init.d/dahdi start, I see initlog -q -c 'modprobe wct4xxp' sh: /sbin/ztcfg: No such file or directory FATAL: Error running install command for wct4xxp doing updatedb then, locate zap returns me /var/lib/asterisk/sounds/spy-zap.gsm /usr/share/groff/1.18.1.1/font/devps/zapfdr.pfa

Hi All, I am having issue when trying to build a custom kernel in CentOS 4.4. Current Kernel Version is 2.6.9-42.ELsmp and the server is HP Proliant DL380 G3. I downloaded the source rpm and then installed it. Gave the command, rpmbuild -bp --target=i686 /usr/src/redhat/SPECS/kernel-2.6.spec. But it throws me an error after patch operations. The following is the error.

I''m currently using the xen-3.0-testing.hg version with the XEN_TARGET_X86_PAE=y complied dom0/hypervisor. I have an HP dl585 with 28GB but the hypervisor boots and says "(XEN) WARNING: Only the first 16 GB of the physical memory map can be accessed...". Xentop shows 16GB. When I boot a RHEL4 2.6.9 hugemem kernel, I can see all 28GB. Any suggestions? Toby

I've apparently gotten myself into somewhat of a bind. I've been trying to exclude various packages from the different repos, and while I *think* I've gotten a working configuration again, it it still pulling stuff in that I have excluded I think in the right repos, but things I have no use for whatsoever. Items like kernel-hugemem-devel, kernel-hugemem, and anything involving

Dear All, I am new in Itanium server Installation and I have installed all the CentOS4.4 ia64 CDs and I have try to install clustersuite packages and i am getting the following error messages like error: %post(package name here) scriptlet failed, exit status 255 and error: %pre(package name here) scriptlet failed, exit status 255 problem Cluster Suite RPMS are ccs-1.0.7-0.i686.rpm

Hello, First of all thanks to the poster on the wiki for centosplus. I've configed it added include and exclude lines, do i need the centos-priority plugin? I want to enable centosplus to use the centosplus kernel and the centosplus webstack. Below are my base, updates, and centosplus repo definitions. I'm getting an error when i do a yum update that a dependency for postfix

Looking for any ideas where I need to look to fix this: I'm installing RHEL3 AS (update 4) on Dell PowerEdge 6850's. I've installed the hugemem kernels on these boxes and need to install and run ocfs. Kernel: ------- 2.4.21-27.0.4.ELhugemem Loaded the ocfs rpm's --------------------- # rpm -qa | grep ocfs ocfs-2.4.21-EL-smp-1.0.14-1 ocfs-support-1.1.5-1 ocfs-2.4.21-EL-1.0.14-1

If you have an AGP video card which you aren't actually using you can try selecting the minimum possible AGP apperture (window whatever) size (possibly even disable it?). This might help. Also removing the AGP card and using a junk 1-8MB svga card will also possibly work. In my experience the linear framebuffer of video cards is by far the greatest memory hog these days. Cheers, MaZe.

I've got a Centos 4 box at work, where I noticed a pile of old kernels lying around and no longer needed. I did "rpm -qa | grep -y kernel > list" then edited the list to remove from it the newer kernels, then "yum remove `cat list`". Yum has come up with a list of 71 packages it wants to remove, even though there were only 33 kernel-related RPMs in the list. this

we have DELL 6800 server with 20GB RAM in it. We like to expand it to 64 GB. I checked Redhat web site and it say max memory is "Architecture & system dependent". Does anyone know what is Max RAM Redhat CENTOS 4.3 (32 bits) support? Thanks. ___________________________________________________ ??????? ? ???????????????? http://messenger.yahoo.com.tw/
