intall problems
by rado 11 May '05

11 May '05

I have just migrated to CentOS 4 from fc3. 3 machines involved k. 2 machines w/raid 1 arrays. Installing these were the problems. 1st machine: just a reg install hda for all the sys and a big drive: hdc for all my backups. This install worked fine. the other 2 machines, w/raid 1 drives...grrrrrrrrrr first of these 2: tried to do a reg install...of course, I had to use disk druid to map out the drives etc then just my reg (everything) install. all seemed to go fine but then when it rebooted...omg!!! 1st thing I saw was a fedora screen then like little things here and there kept referring to fedora...I ended up doing the following install choosing hda drive only...did minimal install (worked fine) then install choosing hdc drive only did minimal install (worked fine) then did my reg disk druid mapping raid 1 arrays and then this install finally worked fine. 2nd machine of these 2: Followed the same procedure as the above and when it rebooted, it hung on (I think it said grub 2) :sigh: I then did the same above procedure as above and it finally took! wow...was not a nice stable experience tho! I keep thinking that it would be a good time if the install systems would do a complete zeroing of the hds, if need be, before formatting the file systems...I just used zeroing as an example but it did kinda freak me out seeing fedora stuff on a brand new CentOS 4 install! thx John Rose -- ...you ever notice the look on your neighbors face when you start talking about linux?

Kernel panic on Dell 1850
by Jason Dixon 11 May '05

11 May '05

I'm attempting to upgrade to kernel-smp-2.4.21-27.0.4.EL (x86_64) on a Dell 1850. The new kernel is panicing on reboot. When comparing against the current working kernel, I just noticed that we're currently running the "UP" kernel: [root@polaris root]# uname -srvp Linux 2.4.21-27.0.2.EL #1 SMP Wed Jan 19 11:49:43 CST 2005 x86_64 First question... why is the kernel version reporting as SMP when this is the UP kernel package? I thought it might have something to do with HT, but no, it's seeing both processors: [root@polaris root]# cat /proc/cpuinfo | grep proc processor : 0 processor : 1 processor : 2 processor : 3 Second question... has anyone else experienced problems with kernel-smp-2.4.21-27.0.4.EL on x86_64? I installed the newer kernel and it paniced on reboot. I'm offsite without console, so I'll be going in tomorrow to take a closer look. Just FYI, here is the information on each kernel we're working with: [root@polaris root]# rpm -qi kernel Name : kernel Relocations: (not relocatable) Version : 2.4.21 Vendor: CentOS Release : 27.0.2.EL Build Date: Wed 19 Jan 2005 12:56:58 PM EST Install Date: Fri 08 Apr 2005 05:44:16 AM EDT Build Host: head Group : System Environment/Kernel Source RPM: kernel-2.4.21-27.0.2.EL.src.rpm Size : 33381631 License: GPLv2 Signature : DSA/SHA1, Thu 20 Jan 2005 10:52:57 AM EST, Key ID 7049e44d025e513b Summary : The Linux kernel (the core of the Linux operating system) Description : The kernel package contains the Linux kernel (vmlinuz), the core of your CentOS operating system.

Software RAID on Centos 4 - new issue
by Nigel Kendrick 11 May '05

11 May '05

OK, I have managed to get software RAID 1 running on my wonderful Proliant server but now have two challenges: 1) Fresh after an OS install and reboot, the RAID array starts to do its stuff but straight away (as part of the boot messages) I am told that the second disk is 'not ready for command' and the system hangs as soon as resyncing starts. I think this is fixed by adding an hdparm line to turn on DMA (I was also losing ticks), but cannot check this because... 2) As part of the testing, I rebooted the system with the second drive pulled out, the whole lot then boots and I can use mdadm -a to add the second drive to the mirrored pair. The drives resync at a decent speed and the pair works fine for the duration, but when I reboot the second drive is not part of the mirrored pair unless I manually add it again. Looking at the md superblock for the second disk, I am wondering if all the attempts at setting up the RAID array have confused it as this is what I get - the last section looks wrong (??) mdadm -E /dev/hde /dev/hde: Magic : a92b4efc Version : 00.90.00 UUID : b0dcd24f:7044414a:1f0ba458:adabce9e Creation Time : Thu Sep 16 06:21:59 2004 Raid Level : raid1 Device Size : 193157440 (184.21 GiB 197.79 GB) Raid Devices : 2 Total Devices : 2 Preferred Minor : 0 Update Time : Wed May 11 09:13:50 2005 State : clean Active Devices : 1 Working Devices : 2 Failed Devices : 1 Spare Devices : 1 Checksum : 2652883e - correct Events : 0.15217 Number Major Minor RaidDevice State this 2 33 0 2 spare /dev/hde 0 0 22 3 0 active sync /dev/hdc3 1 1 0 0 1 faulty removed 2 2 33 0 2 spare /dev/hde Any suggestions on getting this pair talking properly? Thanks Nigel

Multi-homed faq or docs needed
by Michael Rock 11 May '05

11 May '05

I tried to implement a multi-homed box using this faq 4.2.1 split access http://www.tldp.org/HOWTO/Adv-Routing-HOWTO/lartc.rpdb.multiple-links.html But it says table is invalid. Can someone tell me what the difference is in Centos? I assume the FAQ is leaving out how to add tables to the iproute files? I am trying to have eth0 and eth1 service two different subnets for apache and not act as a router. If I use redhat-network-config and set one or both with default gateways one side will not work. So I assume I need to create two routing table files? Can someone point me in the right direction or a better FAQ. thx __________________________________________________ Do You Yahoo!? Tired of spam?

MIrrored drives won't boot after installation
by Jerry Geis 11 May '05

11 May '05

On Cent OS 4 the very last screen says REBOOT. Before click that do CTRL-ALT_F2 and get a prompt. then enter the following commands. This will allow the software raid arrays to boot. grub find /boot/grub/stage1 device (hd0) /dev/hda root (hd0,0) setup (hd0) This is easier the setting up mdXXX commands after boot. Jerry

Dear all I had an issue on CentOS 4_64 with yum that I would like some input on. When running yum, the following errors appear: Traceback (most recent call last): File "/usr/bin/yum", line 6, in ? import yummain File "/usr/share/yum-cli/yummain.py", line 23, in ? import yum File "__init__.py", line 33, in ?

centos 4: java crashes on amd64
by Dario Lah 11 May '05

11 May '05

Anyone experiencing problems with java on amd64? Different versions of java are crashing after few minutes. Googling around reveals that problem is probably in JIT. Disabling JIT makes it unusable (slow) but it doesn't crash. Fix anyone? Hint? Regards, Dario
