[CentOS-docs] What's an Enterprise class OS
Hi all, One of the concepts we see arise on the forums time and time again that's poorly understood is the concept of an Enterprise Class OS and everything that involves. I think it would be of benefit to have a one stop page to point users to that explains the concepts and provides the information required. Much of this content already exists on the Wiki but it is scattered over many individual pages and new users often don't find it (new users often don't search at all!) I'm thinking something that covers the following topics: Relationship with the upstream product stability and long term support (vs bleeding edge) Support lifecycle backporting Not installing software from source ... Much of this could be a narrative linking to existing content on the Wiki where possible - not really that much new content, just bringing it all together in one place in an easy to read/navigate format. Initially I envisaged this as an About type page but that already exists (in title), so maybe something like Understanding an Enterprise Class Operating System. I'd also written a forum post in the FAQ and ReadMe First section on Installing Software: http://www.centos.org/modules/newbb/viewtopic.php?topic_id=14408forum=47 and am wondering about transferring this content to the Wiki too - maybe under the /HowTos/PackageManagement section, and some of that obviously relates to the content above. IMHO it makes sense to have this information centrally available on the Wiki rather than separately on the forums. I guess the reason for this post stems from frustration that the information is there on the Wiki but many new users are simply not finding it (I think forum users are maybe less inclined to search before asking than ML users). This makes me think we need to look at how we can restructure the information on the Wiki to make it more accessible or maybe produce pages that bring together related but individually scattered content in a more structured (easier to find and navigate) manner. ATM we tend to find ourselves writing the same answers over and over again which demonstrates a need for a centralised page covering all of this related content.

First order of business is to replace the single drive with a raid array. Second order was to replace a single iscsi server with duo of machines. If one machine had some sort of non-recoverable problem, the other could pick-up the torch and carry on, even if that means I need to flip a switch to make it happen. My solution for semi-critical stuff (i.e. a few minutes of downtime won't cost the 6 figures it would take to prevent it) has been to use RAID1 in a chassis with hot-swap carriers and keep a spare chassis handy. That way the common case of a disk failure doesn't even cause a slowdown and you can rebuild at an off-peak time without shutting down and in the much less likely case of a motherboard failure you yank the drives, put them in the other box and reboot. But, that means you are probably limited to 6 disks total with half used as mirrors and you still need backups for software or site disasters. The next step up from this would be DRBD to keep hot copies on the spare machine but I've always gotten away with one spare chassis for several active servers (and sometime using it for testing other things too...). You do need to know about the NIC hardware address in /etc/sysconfig/ifcfg-eth? when swapping disks around, though. -- Les Mikesell [EMAIL PROTECTED] ___ I've been contemplating a setup similar to what you're referring to. Basically, take two PC's, (say a Dell PE 860 - I got some of these), and then network-RAID the two PC's, and setup them up with HA to offer one single IP to the network. Thus, if either one of them fails, you still have the other one left. If space (i.e. rackspace) is a problem, then 2x1U's won't cost that much, and they can take 2 HDD's each, so you could seup RAID 1 (mirror) on the 2 HDD's as well. If you can afford 2U space, then you can setup a 2950 with 6 drives each, which has more capacity, and the 2 servers clustered will give redundancy. Has anyone done something like this? What was your experience with this? I know SuperMicro has a chassis that can take 2x small factor motherboards, which means you can setup something like this on the same chassis. -- Kind Regards Rudi Ahlers ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Perl Trouble
2008/11/8 Dirk H. Schulz [EMAIL PROTECTED]: I am running several CentOS 5.2 servers with similar configuration. On all of them I received the following error when using a certain perl module: Base class package Class::Accessor::Fast is empty. (Perhaps you need to 'use' the module which defines that package first.) On most of the servers installing Class::Accessor::Fast manually via CPAN shell has resolved the problem, but there is two of them where this did not help. I know that during setup of these hosts I used yum and cpan shell both to install perl modules; I guess that was wrong to do. Mixing CPAN based module installations with rpm-based module installations is a terrible idea as rpm (or yum) and CPAN install modules in different directories (vendor-perl vs site-perl) so you can (as you have found) end up with two versions of the same module installed. This is a recipe for disaster. My advice is to never mix CPAN installations of Perl modules with rpm installations. And given that the system installation of Perl already comes with a number of rpm modules installed, I only ever add rpm-based modules to that installation. If you want to do CPAN installations then I recommend building your own version of Perl and installing it completely separate to the system installation. You might be interested in by presentation Perl in RPM-Land which goes into this in more detail. http://www.slideshare.net/davorg/perl-in-rpmland-presentation/ Now even an install Bundle::CPAN in cpan shell does not solve the problem. How can I find out what exactly goes wrong there? Googling for the error message does not show up anything helpful. The module that you want is already build as an rpm.

[CentOS] Reinstalled Windows and GRUB - Cannot boot Linux - fstab and grub.conf errors?
Background: This is a dual boot (Windows XP and CentOS 5.2 (32 bit) box. There were four (4) NTFS partitions. The C partition got full. I deleted the 4 NTFS partitions and did a clean install of Windows XP, into one (1) NTFS partition. I knew that I would need to install GRUB again and I did that, using the CentOS 5 Installation DVD.

[CentOS] A broader CentOS information sharing issue? [ Was What's an Enterprise class OS ]
On Sat, 2008-11-08 at 08:55 -0800, Akemi Yagi wrote: snip Many of you on this mailing list may still remember the longish thread regarding the writing of a HowTo rpmbuild article. At that time, I quoted several forum posts to demonstrate the fact that we repeatedly *type* the same answer each time a new person asks the same question. This was because there wasn't really a good single point of reference we could use and the best way of responding was to write the whole thing out (again and again). At lease for me, the most propelling reason for creating a new article is to make things easier for people helping new users rather than to expect new users to read it. And the article/subject Ned is proposing is indeed worth writing. With so many people switching from Fedora and other distros, we have been having so many occasions in which we should explain what an enterprise class OS (thus CentOS) is about. Agree 100%. I just want to mention that the OP, combined with your post, really opens a whole can of worms, when considered in the light of things such as what you mention and the assumption that the user base is growing. I thought it might be useful to the project to think about this. If not, just ignore this please. In projects I've seen in the past, the addressing of things such as _effective_ FAQs, proper indoctrination of new users (in ML, fora and chat rooms) into the _basics_ of the project are usually delayed until the swelling volume forces action to be taken just for sanity/survival of the hittest. :-) Although these things weren't ignored, they are often considered, effectively, in isolation. Consideration or estimations of user-base constituency, user-base size, project growth, degree of confusion experienced by new users, ... often miss the mark. The folks who try to actively help get hit the hardest with repetitive questions. the most frequent symptom of the need for a re-examination. Often these don't make it into a FAQ or other standard frequently referenced place because of a lack of a FAQ coordinator or maintainer or a lack of effective support from the rest of the group in proposing new potential FAQ entries. Further, the new user often doesn't review the FAQ (or other resources) until someone gets really ticked and says something like It's in the FAQ - GO READ IT. Some mild coercion when a user signs up for an ML, forum or chat room could help alleviate that situation. If the FAQ is well maintained, organized, supported by appropriate proposals, and somewhat forcefully introduced to new sign-ups, ML and fora support folks might see reduced repetition and could also use it, via a quick inclusion of a URL, to expeditiously answer some of the oft seen issues. However, this is an isolated stab at a larger problem, IMO. The number of informative articles on the wiki can be expected to continue to grow. There are also many links in the list archives that reference outside resources, such as blogs or other web sites, that answer many questions. This list has already entertained a thread that proposes some consolidation of activity in the fora and mailing lists. Unresolved, IIRC. The basic issue here is that in a project with a user base as diverse as CentOS (regardless of a strong skew of the profiles towards one or another group, like administrators or programmers, or ...), there are too many portals to obtaining information: Planet/People/.../FAQ/Forum/ML/homer page Information drop-down, ... Combined with search engines, all this conspires to overwhelm a new user, especially of the user is in a time-constrained environment where a quick resolution is needed. If my sense of the growing popularity is correct, I suggest that now is a good time to start a thorough discussion about the information infrastructure and ways of ... encouraging new users to use the infrastructure _and_ reduce the number of possible paths that exist to finding needed information. A combination of single path access to all these information resources, a new sign-up introduction to this path, a dedicated support team to keep the components current and a commitment of all those who participate to constantly propose (and generate/maintain where possible) these components should be considered. If something results from this thread, I volunteer to help as I can, although most of you realize that my skills are limited and dated. But I still can learn relatively quickly. It's just that I seem to fit the profile I read long ago: younger folks grasp, retain and more quickly recall details while older folks tend to grasp, integrate and apply concepts more quickly without being as nimble about the details of things.

[homes] comment = Home Directories browseable = no writable = yes hide files = /~*/ Unfortunately after restarting the server the files are still visible. If you have Windows Explorer set to show hidden files, they will appear in a dim color. Quoting from the book Using Samba at http://oreilly.com/catalog/samba/chapter/book/ch05_02.html « Instead of simply hiding files beginning with a dot, you can also specify a string pattern to Samba for files to hide, using the |hide| |files| option. For example, let's assume that we specified the following in our example |[data]| share: [data] hide files = /*.java/*README*/ If we want to prevent users from seeing files at all, we can instead use the |veto| |files| option. This option, which takes the same syntax as the |hide| |files| option, specifies a list of files that should never be seen by the user. For example, let's change the |[data]| share to the following: [data] veto files = /*.java/*README*/ » ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] centralized logs server and also storing the logs on the local server
Hi Friends, I am running most of my company's Linux Servers on Centos 4.x/5.x 32 and 64-bit. I am now trying to configure a centralized logging server where logs of all the linux servers will be stored and also I want to store all the logs on the local server aka means logs will be sent to the central log server but also will be stored on the local server. The reason for storing the logs locally is because we have offices in different cities and few more offices are coming up and it is good to store the logs locally so that when the connectivity b/w the offices break the logs does not get lost. There are lots of configuration available on internet which tells how to send the logs to the centralized log server but I did not find any configuration where logs can be stored locally as well as send to the centralized log. Moreover I am also looking for logs analyzer tool which can generate reports separately for each host for ex there are logs of 15 servers are stored on the server and this logs analyzer tool should generate reports separately for each host.
