Hi, Why does http://www.centos.org/docs not point to say this for example: http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/index.html The latter is more comprehensive. The links that http://www.centos.org/docs contains all have upstream labels on the reading material, so I'm guessing the trademark boundries are not being crossed.

Re: [CentOS] CentOS 6.2 + areca raid + xfs problems
On 04/03/2012 05:58 PM, Tony Schreiner wrote: Two weeks ago I (clean-)installed CentOS 6.2 on a server which had been running 5.7. There is a 16 disk = ~11 TB data volume running on an Areca ARC-1280 raid card with LVM + xfs filesystem on it. The included arcmsr driver module is loaded. At first it seemed ok, but with in a few hours I started getting I/O error message on directory listings, and then a bit later when I did a vgdisplay command there was garbage in that. The file system data are being corrupted. This can only happen either through human intervention or hardware failure; assuming that the original installation was okay. This is a safe assumption to make considering you've reinstalled and it now seems to be okay. I then ran the volume check on the RAID card bios, it flagged 3 errors. When I restarted the system, things were ok, but then the problem reappeared. I ran another volume check and no errors were flagged (I should note, the check takes about 9 hours). but upon restarting, the file system was ok, but then went bad again. Presumably the card bios runs checks only on the firmware and/or the hardware; say disks and the card itself. The reported errors therefore point to those components. Another symptom was that the cli64 raid management utility, which I got from the Areca site would just hang. I would guess the utility is a piece of client code that queries the firmware. Assuming nothing is wrong with the client code, this implies some form of defect occurring in the firmware. Could be unresponsive hardware or corrupt firmware code. After a couple of days of this, I decided I could not afford to have this system unavailable, and I reinstalled CentOS 5.8. Everything has been fine since. The firmware and file system may well have corrected the errors on your first pass. But then for the corruption to happen again without any detected errors sounds inconsistent. There's something missing here. Maybe the card corrected the errors itself the second time leaving corruption behind. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Installing CentOS 6.2 *TO* a USB drive, not installing from USB.
I'm trying to setup a very small system intended for doing monitoring/logging. It's done on an Intel Atoms in a small box and the idea was to simply run it off a pair of USB flash drives in software RAID 1. Now the problem is that while the 6.2 DVD installer could go through the entire install process, grub will load then just stop at the prompt. The system will work if I use a SATA hard disk so motherboard compatibility is not an issue. Attempting the various methods to re-install grub (via rescue mode) or using the grub prompt to setup the disk does not work either. grub just does not seem to be able to find the USB drives. e.g. commands like root (hd0,0) just says device not found. This is despite grub having just loaded from it and despite that grub-install in rescue mode does not report any error. Same problem even if I just go with one USB drive in a plain vanilla ext3 setup. It seems that some sites are saying that EL variants just don't seem to be adaptable to installing and running off USB drives. Is this really the case and that I should be looking at using another distribution or am I just missing some crucial steps in the process? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

This sounds more like something an SELinux rule could do better, and on a per-process basis. Now, I don't have such a rule or policy file written, but I think for this purpose SELinux is the right tool to try to use. You might have to go from the rather lenient 'targeted' policy to the rather difficult to use 'strict' policy to make it happen, though.

There is a 16 disk = ~11 TB data volume running on an Areca ARC-1280 raid card with LVM + xfs filesystem on it. The included arcmsr driver module is loaded. At first it seemed ok, but with in a few hours I started getting I/O error message on directory listings, and then a bit later when I did a vgdisplay command there was garbage in that. The file system data are being corrupted. This can only happen either through human intervention or hardware failure; assuming that the original installation was okay. This is a safe assumption to make considering you've reinstalled and it now seems to be okay. I then ran the volume check on the RAID card bios, it flagged 3 errors. When I restarted the system, things were ok, but then the problem reappeared. I ran another volume check and no errors were flagged (I should note, the check takes about 9 hours). but upon restarting, the file system was ok, but then went bad again. Presumably the card bios runs checks only on the firmware and/or the hardware; say disks and the card itself. The reported errors therefore point to those components. Another symptom was that the cli64 raid management utility, which I got from the Areca site would just hang. I would guess the utility is a piece of client code that queries the firmware. Assuming nothing is wrong with the client code, this implies some form of defect occurring in the firmware. Could be unresponsive hardware or corrupt firmware code. After a couple of days of this, I decided I could not afford to have this system unavailable, and I reinstalled CentOS 5.8. Everything has been fine since. The firmware and file system may well have corrected the errors on your first pass. But then for the corruption to happen again without any detected errors sounds inconsistent. There's something missing here. Maybe the card corrected the errors itself the second time leaving corruption behind. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos i'm not sure what you're saying can be entirely true. What I failed to mention in the original post, is that I did not recreate the problematic data volume during either install; it was preserved both for the upgrade and the downgrade. It doesn't appear that there is any filesystem corruption independent of the raid software, xfs_check doesn't discover any. I'm willing to believe that the raid firmware is problematic, but it seems to be an issue with version 6 but not version 5. I'm in the process of reporting to the BugTracker. As KB mentioned, there is an existing id 5517. Tony Schreiner ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Centos6 iptables startup vs. restart?

My problem is just that the boot-time startup isn't loading the saved state from /etc/sysconfig/iptables, but a subsequent 'service iptables restart' does - and it is something new in 6.x. Did you make sure that the service is active and that the iptables service is actually startet on bootup? Try chkconfig --list iptables to see if it is active and chkconfig iptables on to activate it. Yes, it does start, but the initial rules don't include the port redirection in the nat table. I still think it's a timing problem. Have you checked to see that the proper NAT module is loaded in the kernel at the time when the iptables rules are loaded? At least for diagnostic purposes I would try adding a delay in the startup. You might even find that adding an lsmod into the startup sequence (for diagnostic purposes) there would fix the problem. I have not had a chance to look at the scripts that do this in CentOS 6. Nataraj ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Centos 5.6 Kernel Panics

[CentOS] question on DHCP
If a machine with centos 6.2 is set for DHCP and it looses power and the switch looses power for a long time. lets say a day. so the switch really goes off even with batter backup. Now power comes on, the machine asks for a DHCP address before the switch is read as its not back up yet. there is no response and the machine does not get an address. Finally the switch comes back up , the machine has already posted that it Network got an error as there was no DHCP server. Does the machine ever ask again or do I have to manually do a server network restart or reboot the machine again. It seems to never ask again. jerry ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I would probably start by running MEMTEST and the basic diagnostic tests provided by DELL, which if you don't have installed on your disk can be downloaded in the form of a CentOS based openmange liveCD from somewhere on the dell site. It could also be a disk problem, but from the output you provide I think I would look for memory or IO bus problems first and then look for disk problems if you don't find anything with the first two. It almost looks like a memory controller problem. Nataraj ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Because when I read the grub documentation, it said that hitting tab at the prompt after typing the command will produce a list of possible devices/drives. However, in my case, nothing happens which seemingly implies grub could not find any device. I also did try manually doing (hd0,1), (hd1,0) but none of it seemed to be a findable device. For what it's worth, the installer did see them as sda and sdb. I also disabled the onboard SATA controller during my attempts in order to eliminate it from showing up as a possible device, since grub doc says the (hdx,x) number usually matches the order in which the devices were discovered. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] 3.2 kernel with C5? Or ndiswrapper?

I can see from the boot messages that the kernel is seeing them, but it's failing to mount and switchroot. (of course I can't get useful information 'cos you can't do anything useful after a panic!) Looking at the initrd, it seems to have all the right drivers and modules, and the init script _looks_ correct... but it's just not working. Has anyone else tried to get 3.2.9 to work with C5.8? Or has anyone any advice for getting ndiswrapper to work for me (or other ways of running the N150 card)?

For what it's worth, the installer did see them as sda and sdb. The grub order and names and the linux kernel/udev order and names should not be assumed to have any correlation of any kind, since they are discovered differently. If you can boot a USB live media on this box, you could bring up a grub shell and see how grub sees the disks from that (at a root prompt, type 'grub' and you'll be greeted with the grub shell, and then you can do detection or whatever from that). This also works in the rescue environment given by the install media; you do want to do a 'chroot /mnt/sysimage' in that shell before entering the grub shell, though. It is completely BIOS dependent as to how the devices show up to grub. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I compile 3.2.9, install the modules and then try an boot... and it fails to find my root disk and panics. I can see from the boot messages that the kernel is seeing them, but it's failing to mount and switchroot. Seems to me that your kernel build configuration does not include the FS module, for example, if your root FS is ext4 or xfs you should select it as compiled into kernel not as a module, that should ease a lot of pain. Also the problem with compiling a new kernel is that the vanilla configuration may not work for you and configuring kernel options can be pretty daunting at first and even with each new version new stuff keeps piling in. If you are going the kernel route I suggest to check if you can get the centos kernel config, check if the centos kernel has config build-in, if it does you should have a file in /proc/config.gz which should help you bootstrap the new kernel with the correct options.

[CentOS] virtio or IDE on SBS 2011 (or any domain controller)
CentOS 6.2, using latest KVM drivers for Windows guests. Using LVM for storage, software raid 10, RAW with write cache disabled in the virt manager. When using virtio drivers for disk drives Windows Server complains about write caching being enabled. I can't disable it either. Using IDE prevents this from being happening, however the performance sucks. All searches related to fixing the write cache issue results in it being a controller setting, bios setting or manufacturer flaw. Since this is all software raid, LVM and Red Hat's virtio drivers it doesn't apply (or at least is fixable by others methods). My concern is data integrity over performance, but I'd like to know what others are doing. My fallback plan is to use IDE for the OS and virtio for the Data drive, moving Exchange and the folder redirects to the data drive (or even a different server install attached to the domain), but I'd appreciate others experiences before I resign to dealing with this limitation.

If I try to configure wpa_supplicant then it never associates properly. So I'm not totally convinced ndiswrapper is working for me. So I figured... dammit; let's try a generic kernel. Not good, but... I compile 3.2.9, install the modules and then try an boot... and it fails to find my root disk and panics. I can see from the boot messages that the kernel is seeing them, but it's failing to mount and switchroot. (of course I can't get useful information 'cos you can't do anything useful after a panic!) Looking at the initrd, it seems to have all the right drivers and modules, and the init script _looks_ correct... but it's just not working. Has anyone else tried to get 3.2.9 to work with C5.8? Or has anyone any advice for getting ndiswrapper to work for me (or other ways of running the N150 card)? You might try the uek2 kernel (rebuilt from the oracle sources) for el5 from the testing repo too: http://dev.centos.org/centos/5/ That is based on a 3.1.x kernel, though it is versioned as 2.6.39-* signature.asc Description: OpenPGP digital signature ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] dns cache rbl lists?
No idea where else to ask this and get a real qualified answer but here. Not exactly pure centos questionbut... I am adding blacklists to my postfix smtpd settings. I have the inkling that after the first lookup for a domain or ip that my dns caches the result and I no longer bother the RBL or RHSBL list owners anymore in that instance. Is that correct? I hate to waste their resources if it is not. thanks, bob ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] 32/64-bit Library Sharing and Placement
Good evening... I'm rebuilding much of the gnu toolchain for some development testing I'm working. GMP, MPC, MPFR, PPL, as well as many others. I need to be able to have both 32 and 64 bit versions of these libraries avilable on the system, in more or less the same path (/toolchain/lib, /toolchain/lib64). Generically speaking, is there an easy way to build both 32 and 64 bit versions a the same time??? Or, more specifically, what is the best way to get both versions built???

It is whatever TTL they return, though generally short for two reasons, they and you probably want it so that they can quickly remove entries from the blacklist once issues have been resolved. They want to know how often you query the blacklist, because they want to charge a fee if you are a large site with high volume queries. I guess they need to fund their service somehow.
