I am trying to install CentOS 4.6 to a pair of 750GB hard drives. I can successfully install to either of the drives as a single drive, but when I try to use both drives and mirror the partitions, I start having problems. Anaconda crashes as it is trying to format the drives. This is what I'm trying to create: /dev/md0: 200MB, /boot /dev/md1: 2GB, swap /dev/md2: rest of the

I'm new to lvm. I decided to decrease the space of a logical volume. So I did a: $ df -m Filesystem 1M-blocks Used Available Use% Mounted on /dev/mapper/VolGroup00-LogVol00 1953 251 1602 14% / /dev/sda2 494 21 448 5% /boot tmpfs 1014 0 1014 0% /dev/shm

I am trying to mount this (my old hard drive) from my Centos 5 install as a USB drive so I can copy files over. I have made the change to max_luns so that I can have more than one drive on a USB drive. The first partition, /dev/sda1 mounts automatically as /boot_ The second partition, /dev/sda2 is the one I really want and it is an lvm partition. When I am booted from this drive (as the

I've done a fresh install on a new system with 2 SATA drives, Seagate 80GB each. This is the first time I've done an installation where I used software raid to provide mirroring capability to the system. The raid is level 1 for mirroring. I used the installation documention on RedHat's enterprise site to go thru the installation/configuration for this. I didn't receive any

I'd like to automate the upgrade from CentOS 4.6 to 5.1 as much as possible. Since upgrades per se are not really recommended, I'm planning to do a kickstart installation. However, I want to leave one of the existing partitions (/scratch) untouched during the installation. Here is my current layout (LogVol00 is swap so not shown in the df output below): # df -hl

Hi, I've been receiving message "No space left on device" but there is space. I've forced fsck on reboot 2 times but did not solve. # yum rpmdb: /var/lib/rpm/__db.001: No space left on device error: db4 error(28) from dbenv->open: No space left on device error: cannot open Packages index using db3 - No space left on device (28) error: cannot open Packages database in

Run: # top # vmstat 1 # iostat -x /dev/emcpowerb 1 The latter two you can save to a file. For top, just monitor cpu usage and see if any process is hogging all of it.

Does anybody here have any idea how to make an exact copy of a drive that has LVM partitions? I'm having trouble using dd to do this for an EL5 server. We're trying to diagnose a software problem of some kind and would like an exact, perfect copy of the software running so that we can see exactly what the problem is without disturbing our production copy. It's been admin practice

Hi, One of my servers in a IDC in another country mysteriously went down this morning, and when I contacted the IDC, I was told that XEN doesn't boot up, as follows: [QUOTE] This is error message on the screen " Error 19: Linux Kernel must be loaded before initrd" Server is currently up with 2nd kernel.

I''ve installed a FC5 domU under RHEL5-beta2 dom0 with virt-manager. As the disk for domU I used: phy:/dev/mapper/VolGroup00-LogVol02,xvda,w In the domU I have partitions: /dev/xvda1 on / type ext3 (rw) /dev/xvda2 on /var type ext3 (rw) How do I access these partitions from dom0? For example if I take an LVM snapshot of LogVol02, how do I mount the / partition of the domU installed on

I am installed CENTOS 5.5 on X86. After finish, I tried to apply latest patches. Rpm patch manager say need "dependency" "tzdata-java-20101-1.e15". I search CENTOS 5.5 CD and can NOT find this file. I also search Internet and no result. Can anyone tell me where to download "tzdata-java-20101-1.e15" RPM? Thanks.

Hello Group, I am building a company application based on Centos 5.7 OS. The application was working earlier and creating right partitions both for hardware as well as VM. But since we introduced Centos 5.7 OS and start building application with 5.7 anaconda the hardware partitions are duplicate of VM partitions *while creating hardware partition my code looks like.* cat >

Hi People I just updated a CentOS 5.2 Server that is a Guest inside VMware ESX 3.50 Server using "yum update". As far as I can tell the only three packages were updated Jul 24 16:37:49 Updated: php-common - 5.1.6-20.el5_2.1.i386 Jul 24 16:37:50 Updated: php-cli - 5.1.6-20.el5_2.1.i386 Jul 24 16:37:50 Updated: php - 5.1.6-20.el5_2.1.i386 But when I rebooted the Server one of my

I'm testing doing kickstart installations on Xen VMs. This is the first time I'm trying out kickstart at all, so I rather think I'm doing something wrong in the kickstart configuration than it is a Xen issue. I use a modified kickstart file from an earlier manual installation with a very basic filesystem setup. It fails with "SystemError: vgcreate failed for VolGroup00".

Dear friends: Using Centos 5. I have two physical drives. During install, I made sure to check hdb as well as hda. Both were listed as partitions (which is correct). But my fstab file does not show hdb. How do I make sure that hdb has been formatted and is part of my file system. If hdb is not formatted, how do I format it, please. Sorry for the question. I am a newbie. d[sher at localhost

Hi all, Excuse the question as I'm sure those more experienced will find it simple. I've a CentOS5.1 box with six physical drives, two of which are used for nightly rsync backups. Contents of /etc/mtab, /etc/fstab, df and a brief narrative follow: ====================================================== # cat ./fstab /dev/VolGroup00/LogVol00 / ext3 defaults

When trying to do a yum update, I am told I need more space in /boot. When I check the contents of /boot (ls -l /boot), there are no files. If I do a df -h, there is no available space yet it shows that it has a lot of used space. The fstab shows the following: # This file is edited by fstab-sync - see 'man fstab-sync' for details /dev/VolGroup00/LogVol00 /
