Upgrading to 2.6.11
by Jerry Geis 11 Apr '05

11 Apr '05

What would be the proper steps to upgrade to 2.6.11 on centos 4.0 This is what I think... tar -zxvf linux-2.6.11.6.bz2 cd linux-2.6.11.6 make oldconfig - enter for all choies presented vi .config - change 8250_NR_UARTS to 36 to support 4 - 8 port rs232 cards make bzImage make modules_install mkinitrd /boot/initrd-2.6.11.6 2.6.1.6 cp -f arch/i386/boot/bzImage /boot/vmlinux-2.6.11.6 edit /etc/grub.conf Is this the correct procedure? Thanks, Jerry

trouble booting the system with I2O hardware RAID
by Aleksandar Milivojevic 11 Apr '05

11 Apr '05

I've just made (yet another) CentOS 4 installation. The install process seems to go fine, however the machine doesn't wan't to boot. The system in question has one of I2O Adaptec RAID controllers. I've configured LVM with one volume group and several volumes. If I boot into the rescue mode, all looks fine and dandy. Anaconda finds the installation, and I can access all volumes. However, when doing "real" boot, it gets into trouble. All required modules are loaded from initrd image (as far as I can tell). The I2O modules are able to locate the RAID devices (I see all partitions reported: /dev/i2o/hda1 (unused), /dev/i2o/hdb1 (/boot), and /dev/i2o/hdb2 (rest of the system under LVM). The only thing different from rescue mode is that i2o/hda and i2o/hdb are reversed (this is strange, but it shouldn't affect things since /boot partition has a label "/boot", and all the rest is under LVM, so everything should be device name independent). I have no idea why i2o device drivers behave differently when loaded from initrd image during boot, and by Anaconda during installation. The last couple of messages printed on the screen are: Creating root device Mounting root file system kjournald starting. Commit interval 5 seconds EXT3-fs: mounted filesystem with ordered data mode. mount: error 2 mounting none Switching to new root WARNING: can't access (null) exec of init ((null)) failed!!!: 14 umount /initrd/dev failed: 2 Kernel panic - not syncing: Attempted to kill init! Looking at the "init" script from initrd image, this correspond to: echo Mounting root filesystem mount -o defaults --ro -t ext3 /dev/root /sysroot mount -t tmpfs --bind /dev /sysroot/dev echo Switching to new root switchroot /sysroot umount /initrd/dev Which would indicate that mount of root file system went OK, but then it failed to mount /dev filesystem (basically, move already mounted /dev to /sysroot/dev). After the switchroot /sysroot, old /dev mount point become invalid (non-accessible), the new /dev mount point was not there and of course everything broke from that point on. I've Googled around a bit, and the only relevant thing Google gave me was this French page. There were couple of more pages with similar but different problem (modules failing to load and/or detect disk drives, which is not the case here, all modules were loaded correctly as witnessed by successfull LVM initialization and successfull root file system mount). http://www.fedora-france.org/modules/newbb/viewtopic.php?topic_id=3838&foru… I do live in Canada, but don't speak a word of French (shame on me, but in my defense it is on my todo list). However I did managed to figure out somebody suggested going with Grub instead of LILO. IMO, Grub or LILO shouldn't make any difference, since the error is happening way after boot loader did its job. Anyhow, just for fun, I reinstalled the system from scratch, this time choosing Grub as boot loader of choice to be installed into MBR. However, for whatever reason, Anaconda did not install Grub (dd & less showed no signs of Grub in MBR). Boot into the rescue, chroot, grub-install, OK now I have Grub in MBR. But again, no joy. Grub doesn't even start and system simply hangs in mid-air. No errors printed, no anything. Currently, I'm kind of stuck and idea-less. The system did worked perfectly in the past with Red Hat 7.3 (and LILO as boot loader), and exactly the same hardware RAID configuration (two volumes, one for system, one for data). Any help, hint, etc would be greatly appriciated. -- Aleksandar Milivojevic <amilivojevic(a)pbl.ca> Pollard Banknote Limited Systems Administrator 1499 Buffalo Place Tel: (204) 474-2323 ext 276 Winnipeg, MB R3T 1L7

CentOS Firewall can handle multi IP?
by Franki 11 Apr '05

11 Apr '05

Hi guys, Just a quick question. Can RHEL4/CentOS built in firewall handle multiple IP's bound to one interface? For example on one of my boxes out there I have 64 IP's bound to an interface used in virtual hosting. I searched long and hard for a easy and useable solution without much success. I ended up rolling my own, but it's a hack. Was wondering if CentOS has any answers for me in that regard. rgds Franki

Media check problems
by Kenneth Kalmer 11 Apr '05

11 Apr '05

Dear community I've just noticed that the CentOS 4.0 ISO's I downloaded from ftp.sunsite.org.uk fails the media check on installation. All four fail. The md5 checks pass and I've done 5 full installations from the set of failed cd's and no problems what so ever. I never bothered to do the media check untill a friend asked me what it does... The installation works, wonder what the problem could be? Any suggestions or should I provide more information to help fix this if it might be a bug? Regards -- Kenneth Kalmer kenneth.kalmer(a)gmail.com http://opensourcery.blogspot.com

MailScanner SPAM Forward & Postfix Problem
by Kennedy Clark 09 Apr '05

09 Apr '05

First, thanks to the CentOS folks for creating such as awesome distro! Second, thanks to all for contributing to such an great mailling list! I installed MailScanner/SpamAssassin/ClamAV last week based on the excellent threads that have recently discussed the subject. For folks who missed it, I used Johnny's wonderful guide at http://www.hughesjr.com/content/category/1/14/30/Guides (see Part 4). I'm using CentOS 3.4. On the MTA side, I am using Postfix with a virtual alias table. I want to have MailScanner use the "forward" "Spam Actions" option to put all spam in a central email account (it's a local account on the same server). I can email to this central spam account no problem (both locally and from outside accounts such as gmail). The "Spam Actions = forward blah(a)blah.com" works if blah(a)blah.com is an account on a separate system (such as this account on gmail). However, no matter what I do, I cannot make it work with a local account -- I always get the following postfix error in /var/log/maillog: ..., status=bounced (user unknown in virtual alias table). I'm guessing it has something to do with the fact that I'm using a virtual alias table, but I don't want to get rid of that (even for testing purposes) because it's obviously being used for live email. :-) I know this might be more of a Postfix or MailScanner question, but I thought I would start here. Many thanks for any assistance! Kennedy

Cannot open root device "LABEL=/" on 00:00
by Roberto DaSilva 08 Apr '05

08 Apr '05

I have Centos 3.3 installed on a vmware virtual machine on a AMD Opteron processor. I upgraded the kernel to version 2.4.21-27.0.2.EL, and now when I boot the system I get the following message: Cannot open root device "LABEL=/" Kernel panic: VFS: Unable to mount root fs on 00:00 The server boots fine with kernel-2.4.21-20. I've change the root=LABEL=/ to use the /dev/sda2, and it did not work. Does anyone has any ideas what causes the system not to boot? Thanks. Roberto DaSilva
