CentOS 5 - Problem Installing OpenVZ Kernel
Just to make things clear, i am not new at setting up VPS nodes, i have set up all of my servers with the HyperVM/OpenVZ setup and they work perfectly, but im having a problem with a new server. Just received my new server, installed HyperVM-Slave, rebooted but the OpenVZ kernel was not installed for some reason, so i manually installed the OpenVZ Kernel using the RPM as yum seemed to install the wrong kernel. I then installed the kernel using RPM and got this error at the end of installation: grubby: unable to open /dev/hda: No such file or directory grubby: unable to open /boot/boot.b: No such file or directory grubby fatal error: unable to find a suitable template I have never encountered this error with any of my other servers before... Also after installation everything seems to be correct. /etc/grub.conf has the new OpenVZ kernel displayed, and default is set to 0, so upon startup it should be booting the correct kernel, but the thing is, when i reboot the machine the default kernel is loaded even though the grub.conf is configured to load the OpenVZ Kernel. Im thinking that this may be due to the error i got when installing the kernel.

CentOS 5x But 32bit Or 64bit
2 server configuration will look something like below. I heard that the 32bit kernel is better for the web server since I'll have cpanel on it. Anyone able to confirm this or should I just put 64bit on both of them? Web Server 5420 2.5GHz (Dual QuadCore) 2x250GB SATA2 (RAID1) 2GB RAM DB Server 5310 1.6GHz (Clovertown, DUAL processor) 2x73GB SAS (RAID1) 4GB RAM

Clamav Compile Problem On Centos 4.3 64bit
I'm trying to install Clamav on my Centos box (64bit version) but on the Make command I get the following error: /usr/local/lib/libz.a(gzio.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC /usr/local/lib/libz.a: could not read symbols: Bad value collect2: ld returned 1 exit status make[2]: *** [libclamav.la] Error 1 make[2]: Leaving directory `/root/clamav-0.88/libclamav' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/root/clamav-0.88' make: *** [all] Error 2 I'm guessing is something to do with X86_64 but I still can't find a solution to this.

Openvz Kernel Vs Dedicated Kernal
I have a company offering me the follow: Core 2 Quad Q6600 Processor 1 GB RAM 250 GB Hard Drive 500 GB Bandwidth 5 Usable IPs Free Cpanel The issue here is that they're not real dedicated servers, they're Openvz Dedicated Kernel with Quad Core CPU. The question I have is does anyone have any experience with openvz servers and how does the performance add up compare to dedicated servers? The hosting company says they do it this way because they get cpanel licenses cheap so can give it away for free. Any thoughts?

Centos + Kernel 2.6.9-34.0.2- How To Upgrade Kernel
Last year I ordered a new server with Centos 4.3 and it had the kernel kernel 2.6.9-34.0.2ELsmp installed. It runned fine and I didn't update any packages since then. Today I started getting a problem where both mysqld and kswapd0 uses very high amounts of CPU, spiking up to 100% and my memory usage is at 99% all the time. The problem seems exactly the same as the one mentioned in this thread. In that thread the exact same kernel is said to be insecure and to cause this problem. I also came across a centOS bug that reports this problem with high cpu, mem usage and mysql & kswapd0 consuming all resources. In the linked thread the person solved the problem by upgrading to kernel 2.6.9-42 using rpms but others recommended a newer kernel or a custom compiled kernel for CentOS. Apparently when they used yum it said 34.0.2 was the latest kernel. What should I do to upgrade the kernel, which version should i upgrade to, and where do I get it from? I won't be able to compile a custom kernel and I've only installed basic rpm packages before.

Centos RAID Configuration For OpenVZ
Would this be a good setup for a VPS Serving system with 2x 500gb hard disks (up to) 8gb memory.... (Looking to use OpenVZ to create about 14-15 512mb VZ VPS's)? Host machine to do nothing other than host the VPS's. Host O/S to be Centos 5 x64, guest O/S's to be the usual OpenVZ supported linuxes. Make 2 software raid partitions 120mb, each | +- Make RAID 1, mounted at /boot Make 2 s/w raid partitions Remainder of drive | +- Make 1 LVM Physical Drive, using RAID 1 | +- Make Logical Partition, 20gb, mounted '/' +- Make LP, Swap 16gb +- Make LP. ext3 remainder, mounted as '/vz' Is it important what order I should make the Logical Partitions? Should I create a /tmp partition? If so, how much?

CentOS 5, CPanel 11, Kernel Buggy
(The box, 2 years now, never had issues before all you will read...) I do have a box at the IP xxx.xxx.xxx.xxx, which on 15th Nov. was: AMD 4200+ with 300 GB hdd for OS, and CentOS 4.5 on it... Because the system was facing few load problems of wrong installed applications, we decided to do a fresh OS reload to the latest OS version and cPanel. on 16th Nov, the box was up and running with CentOS 5, and cPanel 11. the kernel is: 2.6.18-8.1.15.el5 After few hrs the box was done and IO restored all backups in it anbd all worked fine, I realized that I couldnt access cPanel, page was blank for everything. Also, most pages (except simple html) where showing internal error 500. I did a reboot. probelm was fixed. After few hrs, problem came up again... I left ssh logged in to see whats wrong. I found out that every few hrs, that issue was happening: Message from syslogd@server at Sun Nov 16 11:47:21 2007 ... server kernel: journal commit I/O error Then, we had techs to check HDD for errors. they did fsck, and said disk has to be replaced (at this point, without wanting to offend anyone, I have to state that 90% of techs in datacenters, or at least at mine --won't name them, 99% you guess which DC it is...-- are just low paid students that don't know SIMPLE things...) so we told them to replace the HDD and do OS reload in new drive... So, on 17th Nov. we had online a new HDD, 400 GB with CentOS 5 loaded in it, and cPanel 11... After few hrs and all working and backups recovered, the issue came up again! This time, with exactly same error, techs told us it may be RAM, so they replaced the RAM and we waited... In 2,5 hrs, bang, it happens again, same error. They say, it might be the sata cable... we replace it... AGAIN ERROR. we ask them to loook at it seriously, and after lot pressure, to avoid case that mo/bo or controller is wrong, they do upgrade us in a BRAND NEW colocated box, which was this time: Intel Core 2 DUO, 6300, with brand new 500 GB HDD and new RAM. We recover in the new box the backups. Box is online today at 18th Nov... and the issue comes up again! Message from syslogd@server at Sun Nov 18 11:47:21 2007 ... server kernel: journal commit I/O error I ask them what the **** is going on now and why after having all hardware replaced with new, and all OS reinstalled clean on new drives and new devices, 3 times, why we have again the same error... And their response: power cable was loose, we replaced power cable... Guys, sorry, this is really DUMP... loose cable cannot give that error... and the error... continues! Also, at this point, I have to let you know, that when this error comes up, (Message from syslogd@server at Sun Nov 18 11:47:21 2007 ... server kernel: journal commit I/O error) the filesystem becomes READ-ONLY and nothing gets affected, if we do a cold reboot by reset button, it comes up again and all work PERFECT, until the issue comes back again..... I am desperate with that, let me know what I have to do!

CentOS 5.3 Default Kernel RealTek Support
I'm not sure if anyone else has come across this but I'm sure you are all aware that CentOS 5.3 default kernel comes with realtek support. But the default realtek drivers have a bug in them when it slows down upload and downloads drastically and shows ping times above 2000+ ms in the same datacenter. A fix for this is simply upgrading the kernel to the latest version available (2.6.29) with realtek driver support.

Install 32 Bit Pae Kernel On Centos
i have a 32bit centos running with 8 gigs, but only 7 is registering when i contacted support they told me Your server does in fact have 8GB of physical memory however the reason it is not being recognized is due to the fact that you are using a 32 bit operating system. By default, the 8GB would be recognized if it were a 64 bit OS however on a 32 bit operating system, you must install and boot into the PAE kernel (physical address extension) for the 8GB to be recognized and utilized. The PAE kernel can be installed through yum when connected to your server as root over SSH. Once you have installed the kernel, you will need to reboot the server for these changes to take effect i tried yum pae install yum pae kernel install both didnt work can anyone give me a quick step by step guide on how to go about this.

we have one box in hivelocity.net that has been down so many times this month that we were forced to remove links to siteuptime where we were once so proud of having a 99.7% uptime for 3 years in theplanet. syslog shows that just before crashing, these entries were made: kernel: kernel BUG at mm/rmap.c:479 kernel: invalid operand:0000 [#1] dmesg also shows this: ...

Choosing 32bit Versus 64bit OS
I'm in the process of preparing to install CentOS 5 on my server, and was wondering whether most people recommend going with the 64bit version or sticking with 32bit. My server's CPU is 64-bit capable (Xeon 3060 at SoftLayer), and I have previously run CentOS 4.4 64bit on it, though I did have some struggles from time to time getting things to work (following setup guides that tend to assume 32bit more often than not). I'll be running just a standard setup of PHP 5, MySQL 5, and Apache 2, powering several moderate-traffic sites that run on the Drupal CMS (e.g. about 7000-10000 visitors per day total, though hopefully more in the future of course). I don't plan on running a control panel other than Webmin, though I might get DirectAdmin or similar in the future to make hosting some friends/clients a bit simpler. Will going with 64bit offer any worthwhile advantage with this setup?

RHEL 5 - 32bit V 64bit Running Cpanel 11 For Hosting
As cPanel is an integral part of server hosting and has the ability of compiling Apache 1.3.x with PHP4 (cgi) and PHP5 (dso) on your server OS. Does anyone know or have baselines/benchmarks for which performs better generally for hosting: 32bit or 64bit RedHat 5 when cPanel 11 has compiled for the Apache and php mentioned above on either of these OS editions? (assume latest versions of apache/php4/5) I was wondering if 32bit performed better or 64bit on a quad core Xeon. Don't forget PHP is compiled for prefork and not multi-threading for Apache 1.3.41 (which are considered legacy 32bit forked apps compiled against 64bit OS). Or rephrased, could i be hampering performance by running it on a 64bit OS on a Xeon (X3210) or improving performance? I'd assume 64bit would offer better all round processing power, or is this a misconception. I recently decided to get a server on RedHat Enterprise 5 X86_64 (64bit), when i wondered if 32bit version would have provided better performance and been the better options for compatibility.

32 Or 64bit & Existing Domain Net Vs New Domain
delving into a new server, a dual opteron w/Centos. Got two questions as I think about setup. 1) 32 bit or 64bit? 2) Regarding host names and server assignemt...I can either assign it as a node to a domain hosted elsewhere in a reseller account, or I can start with a completely unused domain which is currently parked. Any preference, in an ideal world? (I have absolutely no preference, but it occurrred to me it may or may not be of consequence, perfomance & IT-wise and generally speaking .. all things being equal, of course.) Like I said, a newbie. So I'm braced for the if-you-have-to-ask, you-shouldn't-be-in-one" musings for these rather basic boneheaders.

Overselling In OpenVZ
Just how it actually works? I have a pretty good knowledge about Xen and Linux KVM (somewhat about VMware as well). Prior to joining WHT, I rarely heard about Virtuozzo and OpenVZ. I'm just interested in RAM usage actually. I also read on some threads that you can oversell storage and net bandwidth as well? That just seems a little weird to me. I also used a fairly good amount of Solaris Zones as well. Example, if I have a 8GB box and I leave some, say 512MB, reserved for CT0. 8192-512=7680 (I know the ACTUAL RAM amount will NOT be 8192), that leaves 7680MB use for CTs. So technically in OpenVZ if you dice out dedicated 512MB VEs... you end up with 15 right? So you are able to sell more than 15 VPSs on a 8GB server box? If also set all burstable RAM to 1GB for all VEs. In Xen, when you set dedicated RAM it is taken away from dom0, period. That's all there is to it, no oversell (Xen 3.3+ you can use ballooning to overcommit RAM, I know). Within CT in VZ, user is able to check beancounters to see the guaranteed/burstable RAM. Technically you can't lie to the users. I researched around... when oversell in VZ and the RAM gets maxed out... VZ will try to slow/stop/kill processes in order to keep the guests happy, to me that's just dangerous. Why needs to kill processes for RAM saturation? Anyone can shed some lights for me? Or point me to an article(s). It can be technical, I should be able to grasp.

HyperVM+OpenVZ
When you're creating VPS container, you can ssh with that IP and login with your username and password correct? But, what is the problem when I successfully created a VPS, and when trying ssh into it, I can't. Ok, here we go. I want to create a 2nd vps and will be using it as my DNS server. I enter a set of IPs into HyperVM's IPpool. First IP: x.x.x.178 Last IP: x.x.x.182 Resolv Entries (space Separated) : Gateway (IP): x.x.x.x.177 NetMask: 255.255.255.248 Then I created a vps resource plan. And then I created a VPS and it use the first IP from above. I want to connect to SSH and want to make it as my DNS server but seems the IP are not responding, it wasn't even live. So, what is the problem here? Where I did wrong? Just to let you know, I successfully created 1 VPS before that and it works without any hiccups. Got even whm/cpanel installed as well on it. The thing that I suspected is that my DC pulled the IPs off me and assigned them to other server. Waiting for their reply on this though.
