i see one available in the repos, but i don't recall seeing any announcement about it. from googling, it does seem to be real, but still a bit disconcerting to not have an announcement about it.

Software RAID 10?
by Mickey Everts 02 Apr '07

02 Apr '07

Hello... I have a server with 4 x SCSI drives and I would like to install Centos 4 (or 5) onto a software RAID 10 array. Do you know if this is possible? I noticed that under the Centos 4.92 beta, RAID 5 is an option but for some reason RAID 10 is not listed. There does appear to be a RAID 10 module.... /lib/modules/2.6.9-42.0.8.ELsmp/kernel/drivers/md/raid10.ko More info I found here: http://cgi.cse.unsw.edu.au/~neilb/01093607424 Many thanks for any help on this; I hate to buy hardware raid controller if not needed....

LVM & Softraid & expansion
by Cen Tos 02 Apr '07

02 Apr '07

I've been reading the RHEL 5 manual/guide linked from centos, and the idea of LVM with expandable partitions seems like a great idea (yes duh why else would it exist if not?). Although the documentation shows a screenshot of how the final setup would look like with LVM & RAID together, it doesn't actually gives the step. 1. Am I correct in thinking it should be done in this way - setup Softraid - setup LVM on the raid partitions Secondly, LVM allows expansion of the LVM group when we add a new drive. But with softraid, how will this happen? Searching around does not turn up any guide on this. Am I correct in thinking I must always add new drives in pairs (for Raid 1), create a new softraid partition then assign this new partition to the LVM group? Thanks!

CentOS 5 beta upgrade path
by eric＠austinconventioncenter.com 02 Apr '07

02 Apr '07

How hard would it be to upgrade from CentOs 5 beta to the released version? Would it be as simple as a yum upgrade or would I have to upgrade via booting from cd/dvd/pxe ? Pardon my ignorance if this has been asked already -Eric

How to resolve an up2date package conflict?
by Olaf Greve 02 Apr '07

02 Apr '07

Hi, At present I'm setting up several CentOS (4 and 4.4) machines, and in the process of installing the several updates that are automatically mentioned by up2date as being available, I'm running into a package conflict. More particular, when trying to install several of the C compiler related packages (like gcc, cpp, etc.) I get the error message: "Test install failed because of package conflicts: The following packages were added to your selection to satisfy dependencies: (name) libtool (version) 1.5.6 (release) 4.EL4.c4.4 package libtool-1.5.6-4.EL4.1.c4.4 is already installed" Now.... this seems to be somewhat of what we call over here a "chicken-and-egg-problem", IOW, in order to resolve it libtool should be added, yet when adding it, libtool is already installed and causes the conflict; so which to solve first :P Can anyone let me know how I can manually solve this problem (note that libtool was not offered as a selectable package, but rather is enforced when trying to install e.g. gcc)? Tnx in advance, and cheers, Olafo

Performing a test install of CentOS 5, I no longer have the capability of requesting a minimal install as their was in CentOS 4. Is there any possibility this could added back in before final release? Thank you, Brett

Wait for 5 or just use 4.4?
by Cen Tos 02 Apr '07

02 Apr '07

I'm a relative newbie to all this so pardon me if the following are all stupid questions. Firstly, I'm setting up a web server and gone from planning to use Ubuntu (due to some familiarity as a desktop at home) to CentOS based on recommendations by experienced webhosters. However now that I looked into CentOS, I find myself at a point where it's transitting to a major new version. So the key question for me is, should I wait for CentOS 5 to be released or just go for 4.4? Being rather new to Linux, my attempts to try to figure out the differences between the two has been rather futile since I can't readily tell what is really important to me or not. All that I think I'm sure of now is that 5 would support virtualization using Xen and 4.4 doesn't have it. This alone is food for thought since the idea of being able to compartalize each website in their own VM sounds good in the long run. I'm tempted to wait for 5 since I'm reluctant to run the risk of having to upgrade a live server to version 5 and have it failed specutacularly if I screw it up. On the other hand, it's uncertain when 5 will be out and definitely waiting more than another 2 weeks isn't quite acceptable without compelling reasons. Hence I'll appreciate it if the knowledgeable folks on this mailing list can advise which is the wiser route to go. Some additional information which may be relevant to the decision. 1. RAID : Was planning to run "hardware" RAID 1 on the server and has noted comments that software RAID 1 on Linux may be better than raid 1 using onboard firmware controllers. 2. Software that would be running on the server would include Apache 2.xwith ASPx support, php 5.x, MySQL 5.x, Exim, ProFTPD, Direct Admin (supposed to be developed on RH and one user apparently tested it to work right out of the box with 5 Beta, part of the reason why I decided to go with CentOS) 3. Hardware to be used would be Intel Core 2 Duo on an Asus P5B-VM-D0 (Q965, ICH8-D0, Intel GMA3000 GPU) with SATA hard disks. 4. Network bandwidth control based on request IP or domains (i.e. connections to IP #1 can be limited to 512Kbps, while connections to IP #2 can be limited to 1024Kbps, or connections to www.domainA.com is limited to 256Kbps etc. Thanks!

Missing samba binaries
by Mark Hull-Richter 02 Apr '07

02 Apr '07

I went to enable samba on my home machine, which has a largely plain vanilla install of CentOS 4.4 Plus, and the smbd and nmbd files are missing. As you may know, this makes it rather difficult to run samba. For some reason, the winbindd binary is present, and rpm reports: samba-common-3.0.10-1.4E.11 samba-client-3.0.10-1.4E.11 as present. So how do I retrieve the missing samba binaries/ Do I remove and reinstall the packages, or do I rebuild the latest samba from source, or . . . ??? Thanks.

Centos 4.92
by John Summerfield 02 Apr '07

02 Apr '07

I'm looking at the first ISO image (I only have two so far), and I don't see instructions a repo for preparing for a network install. It used to be basically copy all the RedHat/Fedora/CentOS directories to a common location. Then one booted from the network, CD or whatever and gor right into it. The last part I'm sure is substantially the same as before, but we do need a new recipe for creating the repo. If it's "on the internet," I can't get at it at present; nor will I for a few days. -- Cheers John -- spambait 1aaaaaaa(a)coco.merseine.nu Z1aaaaaaa(a)coco.merseine.nu Please do not reply off-list
