Too me it looks more clearly arranged this way. Thank you. I tend to read documentation all the way through before following it, when I read it at all ;). So, I didn't initially understand the depth of emotion that appeared to be expressed over the previous version. (simplified english: Russ seemed very annoyed.) But, with Russ's patient explanation and a bit of thought, I think I understand what he was saying. I think both points of view are valid but the new organization is probably more applicable to our audience. I hope the new document is more useful as a reference document and produces less confusion. It occurs to me that I could separate the vhost.d/ and virtual disabling sections into separate Tips articles. Please let me know if this is desireable. Is that desirable? You're weighing options here (do it this way or do it the other way), so I don't really see how that could be split out in a sane way. Yes. I think so, as well. However, the document is getting a bit large for a tips page and goes slightly beyond the stated scope. If that isn't an issue, yet, I don't have an issue with leaving it as a single document. For example, we could split the restart section into a separate document and expand the explanation a little.. Then, this page and other potential Apache tips pages could refer to it by command and link. The disabling virtual hosts could probably be put into a separate doc, though it depends on putting the virtual host config files in a directory, so both docs would need to refer to each other. The potential pitfall here is that no single document completes a thought and the referrals fly, apparently endlessly. I sometimes have trouble drawing the line. The axiom, In for a penny; In for a pound, seems to exclude, or maybe ignore, the idea of only being in for tupence. Certainly wouldn't be the first to question my sanity, though. The other thought I had is collecting all the Apache tips into a howto, but I'm not ready to accept the responsibility to create and maintain it, nor do I have the confidence that it would be sufficiently authoritative.

The user should be instructed to start rescue mode with networking in order to be able to retrieve the patch for mkinitrd. The mkinitrd instructions should be moved to the beginning of the guide. Networking sometimes requires very complicated configurations which could be quite hard to load from the rescue mode (imagine using ndiswrapper for example). May be we could provide a patched package which will replace mkinitrd, perhaps in centos-plus repo? 3. Some additional discussion on how to handle multiple partitions should be added. There is an implicit assumption that only / is used. Ideally we should also provide a guide for the LVM case. I had an email discussion with William Schwartz, who was making partitionable RAID1 with LVM setup and managed to do that. The changes are: 1. Additional steps were required to start LVM manually after starting raid with mdadm: vgscan vgchange -ay VolGroup00 # I think name could be omitted - Lev. 2. grub boot options are certainly unchanged in LVM case. 3. pvscan and Co. will detect false volumes or complain, so something like this needs to be added to /etc/lvm/lvm.conf: filter = [a/md*, r/.*/] William wrote that he did not do this last step and things work fine for him. -- Lev. ___ CentOS-docs mailing list CentOS-docs@centos.org http://lists.centos.org/mailman/listinfo/centos-docs

[CentOS-virt] VirtIO with CentOS 5.4
Hi, all, I'm attempting to run a Windows 2003 (32-bit) VM under CentOS 5.4, generally following: http://wiki.centos.org/HowTos/KVM I've seen nice performance benefits with the VirtIO driver under Fedora, so I'd like to get that running with CentOS as well. I have the September drivers build .iso. According to: http://www.linux-kvm.org/page/Virtio I need a KVM version 60 or later - fair enough. Back at the wiki there's a note about later KVM in -testing, and sure enough there's a -66 there, but it's only built for an old kernel. I got that SRPM and tried to build it against the current kernel, but get kmod build errors, ala: /root/rpmbuild/BUILD/kvm-kmod-66/_kmod_build_/kernel/external-module-compat.h:421: error: redefinition of typedef 'bool' ... /root/rpmbuild/BUILD/kvm-kmod-66/_kmod_build_/kernel/external-module-compat.h:734:1: warning: __aligned redefined The wiki also has a note about -84 being in Levente Farkas's repo, but those don't appear to be there any longer.

Basically, whatever process I am doing hits 100% cpu usage in Windows. If I open IE, it will use 100% cpu for a bit while it opens. If I try to click on a website, it will do it again. Thus, it is causing a very sluggish session as it keeps pausing. It isn't just IE, it's any program I try to use.

[CentOS] Xorg without xorg.conf (a bit OT)
I like to try out other distributions of Linux. Today I took a look at Mint Linux 8 and Fedora 12. I installed and updated each on a small partition -- actual physical install, not virtual machines. Both worked great at 1280x1024 (their defaults) but neither would let me use 1024x768 resolution. Both came with newer versions of Xorg, neither of which build an xorg.conf file. Mint gave me three settings, 1280x1024, 640x480 and something like 700x400(?). Fedora gave me the choice of 1024x768, but when I tried to use it, it just went black until timing out. When I downloaded and ran system-config-display, it built an xorg.conf file, which I modified to 1024x768 (by removing the 1280x1024 selection). When I tried rebooting, it locked up. (I have an Intel 865G video chip, BTW.) So, what is it about the newer versions of Xorg that doesn't like 1024x758 resolution? At least not on an Intel Graphics chip? Just weird. And I'm curious as to how Xorg determines its monitor resolution choices when there is no xorg.conf file. Is there a good tutorial on this subject available? Frustrating situation -- and I'm still nervous that Red Hat 6 is going to end up with the same issue -- if this is an Xorg problem with Intel it seems reasonable to assume that they will inherit it. -- RonB -- Using CentOS 5.4 ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Hi everybody, I have a CentOS 5.4 server I need to se-up as Subversion server.

I am now trying to set it up so that after login the default keyring is unlocked. This way I won't be asked for the keyring password ever. I have followed the instructions found at http://fedoraproject.org/wiki/Tools/NetworkManager#Gnome-specific_information but it doesn't work. I have rebooted the server few times with no avail. I have checked that my password and the keyring password are the same. Every time I run a Subversion command I'm prompted for the keyring password. Can anyone help me?

[CentOS] trouble shooting slow ssh logins
Hi all, I noticed that my ssh logins to a particular server were taking up to 5 seconds to finally login. My tcpdump -vv weren't producing much output (not good) and my pings to and from that host were normal and almost identical to other hosts on my subnet that had no ssh login delay issues. Log files also showed nothing alarming. My hosts file was missing this at the very end of the file; ::1 localhost6.localdoamin6 localhost6 I chose to disable ipv6 during install but no big deal that I needed that line. My question is; What tools could I have used to trouble shoot this as packet sniffers on the switch port or the host didn't seem to do the trick, nor did log file analysis? I just had a hunch and decided to look at my hosts file, not the most effective way to fix issues but one I've used several times.

You can also run SSH in debugging mode on the server, and increase verbosity on the client. See the man pages.. I usually just fire up another sshd on another port and test with that. nate ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

DNS was normal, forward reverse lookups exist and match that host. I'll turn on ssh debug and remove that line at the end of hosts to see what happens.

[CentOS] /proc/mounts always shows nobarrier option for xfs, even when mounted with barrier
Ran into a confusing situation today. When I mount an xfs filesystem on a server running centos 5.4 x86_64 with kernel 2.6.18-164.9.1.el5, the barrier/nobarrier mount option as displayed in /proc/mounts is always set to nobarrier Here's an example: [r...@host ~]# mount -o nobarrier /dev/vg1/homexfs /mnt [r...@host ~]# grep xfs /proc/mounts /dev/vg1/homexfs /mnt xfs rw,attr2,nobarrier,noquota 0 0 [r...@host ~]# mount | grep xfs /dev/mapper/vg1-homexfs on /mnt type xfs (rw,nobarrier) [r...@host ~]# mount -o barrier /dev/vg1/homexfs /mnt [r...@host ~]# grep xfs /proc/mounts /dev/vg1/homexfs /mnt xfs rw,attr2,nobarrier,noquota 0 0 [r...@host ~]# mount | grep xfs /dev/mapper/vg1-homexfs on /mnt type xfs (rw,barrier) Can anyone else confirm this behavior?

Ever since updating to the latest *.164* kernels, we have mysterious machine lock ups. Sometime there will be an oops message, other times there will be none. The oops messages aren't the same when we manage to get one. Sometimes a machine will just drop off network without even a blip on the serial console. I still have to try to get a memory dump from one of the machines to see if I can find anything there, but I'm curious if anyone else has run into the same issues. Never mind.
