Does it need more (or less) background info ? Or more (or less) substance perhaps ? Regards, Jasper I'd like to see more info on things like: - What is the relationship with swap? - How/when does swap get used instead of RAM? - How do I determine the size of RAM to use? - What impact does using 100% of RAM have on the active memory in the system? - What happens if all system RAM is full, and tmpfs is also full? I think your doc is a good start, but as of now it's got the same info as all the other tmpfs docs out there, and they don't go into much detail about the real impact on a system when using tmpfs. Tmpfs is billed as a more sophisticated ramdisk, so docs addressing it should go into the details of what makes it better. A simple ramdisk just allocates a chunk of RAM, so why is tmpfs better? ___ CentOS-docs mailing list CentOS-docs@centos.org http://lists.centos.org/mailman/listinfo/centos-docs
[CentOS-virt] Error setting up bridge with static IP address
Hello: I am trying to follow the RHEL virtualization guide to set up a bridge on a system running CentOS 5.4. I copied my ifcfg-eth0 to ifcfg-eth0:1 and set its content to this: DEVICE=eth0:1 HWADDR=[The MAC address from eth0] ONBOOT=yes BRIDGE=br1 I then created ifcfg-br1 with this content: DEVICE=br1 TYPE=Bridge BOOTPROTO=static BROADCAST=192.168.2.255 IPADDR=192.168.2.202 NETMASK=255.255.255.0 NETWORK=192.168.2.0 ONBOOT=yes DELAY=0 When I do service network restart, I get this error: error in ifcfg-eth0:1: didn't specify device or ipaddr I specified the device so it looks like it wants an IP address but that is contrary to what I am reading on the Internet.

Re: [CentOS] EDAC Kernel Panic 2.6.9-78 and above
Chris, I've got a production system running CentOS 4 that was rock solid until I upgraded from 2.6.9-55 to 2.6.9-78.0.13 (now running 2.6.9-89.0.11). The system now crashes intermittently after a few weeks. I finally caught the panic message : EDAC MC0: INTERNAL ERROR: channel-b out of range (4 = 4) Kernel panic - not syncing: MC0: Uncorrected Error Looking at the kernel changelog, I see that EDAC support was added for the Intel 5000 chipset in 2.6.9-68.20.EL which this server runs. Same issue here with a machine running centos 5.3. The problem began with a kernel update that introduced the 5000 chipset. See the thread RAM errors after kernel-update for more details. I couldn't solve the problem yet, but because the machine crashes every two days with this kernel, I had to boot an earlier kernel without chipset support. I'm trying to determine if this is a potential memory issue, or is this related to some other hardware item. Also considering disabling EDAC in the kernel (is noedac a valid option?) as a last resort. I will run memtest86+ on the server as soon as possible to check the memory, just formulating my game plan if it's something else. Don't use the memtest86+ version that comes with the centos ISO. There is a much newer version available from the authors website. Only the new version identifies the chipset correctly. -- Mit freundlichen Grüßen Michael Schumacher mailto:michael.schumac...@pamas.de ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Casale jcas...@activenetwerx.com wrote: which is about as useful as Microsoft Windows support... is it broken? reinstall windows FFS, this attitude amongst opensource guys that MS is the devil and are trying to murder your family or sabotage your life is such BS. I don't know what Microsoft's support is like for servers, but on the desktop they *definitely* tell you to reinstall for almost any major problem. I don't work on computers for a living anymore, but my wife is always telling people that I can help them when their Windows computers go down. An older lady at our church had a Vista machine go KSOD (black screen of death on her). It was a fairly new Dell. I called them and explained to them that I couldn't get it to boot -- they gave me instructions on reinstalling. Microsoft's support suggestion was to reinstall. I found out later why, there must have been 10 different ways to fix KSOD (that worked for some people but not others) and I tried every one. Finally using MSCONFIG I was able to open a hive (I've purposely avoided Vista so this is all new to me) and backed up the user directories to a portable hard drive. And then I did what I almost always have to do with Windows... reinstalled it. The KSOD event occurred after an automatic Windows update (which isn't all that uncommon I found out). Take the Tin Foil Hat off and settle down, MS support is easily on par w/ or *the* best support there is. Again, telling you to reinstall is not good support, in my opinion. I maintain both Linux/Unix and Windows machines, and since high school days I have been using PSS and there is nothing like it. They have have *ALWAYS* fixed everything but one issue I have had, where that one issue I resolved before them. Okay, what did they tell you about KSOD? Even if I can't fix it, I would at least like to know what really causes it. (There are a lot of theories out there.) Spreading your FUD reflects on _you_ not MS. All he said is that they tell you to reinstall which is what they do. It's not FUD. I love Linux (and prefer to toil in this forest) but don't preach that anti-ms crap, its utter malarkey. Seems to me you're a little bit too sensitive here. I've reinstalled Windows on many personal computers for friends and family, and have seen many Windows computers re-imaged in the corporate environment. Reboot and/or reinstall are two of the most common fixes for Windows. This is not tin-hat malarkey, it's the simple truth -- and it's one of the big reasons I moved to Linux. -- RonB -- Using CentOS 5.3 ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Caught between a Red Hat and a CentOS
Remember that windows integration website ( don't remember the name but related to nLite and ryanvm) shutdown by Microsoft - it made a great deal of news because they had scripts to take out annoyances such as balloons popping up in the taskbar. MS lawyers had them disbanded For a good reason, because silly non-admins where using nlite in a corporate environment? WTF, if you take all of RHELS rpms and recompile them in an unsupported manor then call for help, what do you think they will do? You have got to be kidding me, ms should just support anything anyone wants to do? Sigh... It takes way too much time to install a windows system from scratch, configure how you want it, and then install all the apps on top and then all the updates and then all the updates to the apps ad nauseam. Oh, you want to image that harddrive now? Well you get 3 attempts with sysprep and then you start all over - no thanks.. Well, if you need some guidance on how to do this, I would be willing to help. Even at home I use RIS/WDS and deploy almost all of my apps to windows lab vm's with GPO's. So, unfortunately yes, I do *completely* automated deployments that setup all my apps and even pre-populate some settings at the push of F12. When I didn't have this knowledge, I never assumed Bill was an a$$hole, I took the time to learn it. Same with Linux, when I never had kickstart knowledge and couldn't automate my CentOS deployments, I never assumed KB or the CentOS devs were scumbags, I took the time to learn it:) Guess what, now I can do both!

Bottom line is, I work with both and quit successfully get equivalent uptimes and QOS with both. Many guys do it, it's possible. I met one of the guys who did the barnes and noble setup at an msdn conference, I guess that successful setup wasn't the result of competent guys who actually knew their sh!t and did a good job, but just dumb luck.

It wasn't a BSOD, it was high IO across a set of spindles with VSS enabled and setup wrong by my corp. What the entry tech (as it wasn't yet elevated) didn't know was specific details about how my fileserver was utilized which had an impact in my scenario.

Cheers, Niki ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos Hi, The suggestions offered by other posters to install/use a monitoring/polling/graphing system is a fine idea. Using something like Cacti is great for collecting and viewing historical data. However for looking at what a server is doing _right now_, that kind of system falls short. I think your original idea is spot on! I do exactly what you suggest. I keep a minimal X install on most of my headless machines -- I still boot run level 3. This lets me ssh -X to a machine and execute graphical commands, and up the come on my local Linux workstation. Occasionally, this is very useful for me. For instance: I have some of these headless boxen scattered throughout the network. With this, I can launch firefox on a remote machine. This lets me test viewing resources from various points of the network; great for security policy testing. What you're talking about works great too. I have gkrellm installed on these machines too, as well as the servers. Cacti is great for looking at trending or historical data. But to see what a server is up to _right now_ I fire up gkrellm this way (along with things like tail 'cat /var/log/_something_' and htop) to see what the machine is up to right then and there. gkrellm is available from the wonderful rpmforge repo, but I'm sure Conky would work too.

[CentOS] full-fledge PDF editor for Linux
Hi all, Does anybody know of an editor that can do on Linux what Acrobat / Acrobat Pro can do on Mac/Windows? I have tried to use the PDF Import extension to the Open Office which appears barely functional - at least it is so slow as to be almost impractical. I have also tried pdfedit under Linux which seems to work fine but seems to have rather limited functionality. For instance, the capability to make bookmarks or to search through the whole document (as opposed to the current page) seems to be missing there. Any tips much appreciated.

For instance: I have some of these headless boxen scattered throughout the network. With this, I can launch firefox on a remote machine. This lets me test viewing resources from various points of the network; great for security policy testing. What you're talking about works great too. I have gkrellm installed on these machines too, as well as the servers. Cacti is great for looking at trending or historical data. But to see what a server is up to _right now_ I fire up gkrellm this way (along with things like tail 'cat /var/log/_something_' and htop) to see what the machine is up to right then and there. gkrellm is available from the wonderful rpmforge repo, but I'm sure Conky would work too. You can take this one step further by picking an always-on host where you run freenx. Then connect with the NX client from www.nomachine.com and start a desktop where you can park long running jobs like monitoring tools (including remote X connections or a bunch of xterms with ssh connections elsewhere). Then you can disconnect the NX client and reconnect later with everything still running. The connection can be from any linux/windows/mac NX client and you get very good remote performance even over low bandwidth connections - and unlike normal X connections, losing the connection doesn't kill the processes. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Now the oracle dba has strict parameters on what versions can be installed and which can't. The rpms in c:/install meet those requirements. In addition, since this is a production machine, it can be down at most for one day. So all I want to do is upgrade what's currently on the system. Moreover, if something horks, I want two chances to back out (the second being asking the backup guy to put the system back to yesterday). The command to do this would be rpm --freshen --repackage * run in that crazy c:/install directory (or what the redhat guy called, a folder). This command runs fine for one file which has no dependencies (i.e., change '*' to a specific rpm). It also upgrades three or four co-dependent rpms if they're narrowly specified. But if the file/rpm spec is '*', rpm complains about two missing dependencies and stops. Yeah, this directory contains 1507 rpms (IIRC)... which is a lot, but it should still work. This is Linux, after all. And there's plenty enough memory and cpu to handle it. Running rpm --freshen --repackage * for 1500+ rpms probably exceeds the maximum character length for some part of the system after expansion of the '*' by the shell. Try breaking it up into smaller chunks (say two or three hundred at a time). You can match subsets of the files using shell expansions like rpm --freshen --repackage [a-g]* and tweak the line for any dependency complaints manually. Alternatively, use 'createrepo' to create a Yum repository of the RPMs and use yum to handle it for you. -- Benjamin Franz [The rh support written response was that there wasn't a problem, that this was expected behavior.

[CentOS] Openfiler question - fiber channel?
Hey folks, I don't seem to be able to get a response from the openfiler forums (and they want 40 quid for the fine manual!), and since there has been a lot of chat about it here lately, I figured I'd ask here. Please forgive my terminology as I am just making my first baby steps into iSCSI and Fiber Channel, and am not very well read on the matters. So I could be using the wrong terms (anyone got a good primer to recommend?) It seems straightforward that I can install openfiler to server iSCSI disks out over the network. And it seems obvious to me that I'd want a dedicated network for doing that. That part is easy. But based on some poking around on the openfiler site and in the forums, it looks to me like it might be possible to stick a fiber channel card into an openfiler system, and serve fiberchannel out to other systems? Is that right? Is anyone here doing this? This does tie back in to CentOS directly because most of my systems are CentOS, and I'd eventually like to migrate them in this direction, depending on what comes of my benchmarking thanks, -Alan -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of In Defense of Food ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Which will not match these connections since the dest port is not 25. I could put a RELATED, ESTABLISHED line in for source port 25, but as you said, the ACCEPT all line should catch them anyway. -- Bowie ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Upgrade to 5.4 with an existing XFS-filesystem
Hi! I've got a fileserver currently running under 5.3 with the /home-partition being an XFS-filesystem. I use the kmod-xfs from extras. It works great ;) Now: as I understand it from the release-notes the 5.4 kernel has XFS already built-in. Right? Or is it just a kmod-package (technology preview) Now my question is: are there any recommendations for an upgrade-procedure? I mean, I can probably manage, but I'll want to minimize downtime Bernhard BTW: when doing yum list updates I don't see any kernel*-packages in the list. Is this because the last kernel from the 5.3-updates has the same build-numer (164 I think)?

[CentOS] openfiler (was: using CentOS as an iSCSI server?)
Simple, it's only a NAS device, and not really a file server / web server / data base server as well. Here is something I am currently lokoing at, and wondering if you'd considered it or if anyone here has done it. I've got a bunch of existing hardware - really good IBM stuff that is all installed with CentOS (with a few exceptions). We want to move to virtualization, but the direct-attached storage is a bit of an issue because with VMWare ESXi you cannot do some of the fancy stuff like VMove (moving a live running server from one host to another). So of course Openfiler comes to mine. However, most of this hardware has pretty significant CPU and RAM horsepower, so just running it as openfiler would be quite wasteful. What I se some people doing is - install ESXi (4.0) onto the bare metal - install openfiler as a virtual machine - give open filer all the disk - serve the disk out to other VMs via openfiler This may seem redundant vs just doing it without openfiler, but as mentioned a lot of the fancy features you only get with virtualized disk. I am about to do some benchmarks on this stuff to see what percentage of performance I give up for doing it this way. -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of In Defense of Food ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Doing that for the most part defeats the purpose of using things like Vmotion in the first place, that is being able to evacuate a system to perform hardware/software maintenance on it. Myself I have 12 vSphere ESXi systems deployed at remote sites using local storage, they run web servers mostly, and are redundant, so I don't need things like vMotion. Local storage certainly does restrict flexibility. Over complicating things is likely to do more harm than good, and you'll likely regret going down that path at some point so save your self some trouble and don't try.

[CentOS] Console priority
Hi all, A while back I vaguely remember someone posting a link to documentation on how to prioritise console access (for want of a better expression). For the life of me I can't find it in the archives or via Google; Can anyone provide a URL? Basically, I have a remote server that thrashes (that's my theory at least) occasionally, resulting in the service (httpd/mysql) failing. When its in this state logging on to the console (serial + screen) responds with login timeout. The only way back from this at the moment is a reboot.. If I can prioritize console access somehow and get on to the server I may find a clue as to what's causing it.

Also can be a good way to kill off prospects of using vmware if budgets are tight. When people think vmware most of them instantly think enterprise version and several thousand $ per CPU. Sort of like when people think Oracle they instantly think enterprise edition and $40k+ per cpu. I've been running vmware since 1999 and have never used vmotion beyond basic eval stuff. Currently I've got more than 350 VMs running in production and QA and none of them can do vMotion. Combination of ESX/ESXi and version 3.5 and version 4.0. In total about 34 servers, 12 of which are off site(using local storage mentioned earlier), the rest use fiber channel to a high end storage array. From a blog entry I wrote recently - http://www.techopsguys.com/2009/08/25/cheap-vsphere-installation-managable-by-vcenter/ However, once I get a quote I'll probably find out I cannot afford it anyway. See.. The core set of vmware features has gone down in price(not taking into account ESXi) more than 90% in the past two and a half years. For me and my 350+ VMs thats a steal. That said I am pushing to go to a advanced version for next year with new HP cClass blades and 10GbE. But I sold the company on vmware with the lower end stuff and have made it perform flawlessly for the past 14 months or so. Now they see the benefits and want the higher end stuff for production anyways, and to get production onto modern systems, currently running on 4+ year old HP DL585G1s. nate ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I've done it experimentally. It worked. Obviously you can't share a raid volume with multiple client hosts. 2) two ISCSI servers, each with identical storage, configured as active-standby cluster, using conventional cluster management software. active 'master' replicates block storage to 'slave' using DRBD. I've done this too (active-active using RH Cluster and GFS). I gave up finally because I just couldn't get reliable multipathing.

[CentOS] conventional cluster management software
I saw this in the openfiler thread, and realised it is another major hole in my knowledge What do you all use for clustering, and does it run out-of-the-box with CentOS? My main areas of interest are : - DB clustering (PostgreSQL) - yeah, we're looking at commercial stuff and skytools - web server clustering - Apache on CentOS - storage clustering thanks, -Alan -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of In Defense of Food ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
