similar to: md0 and moving to another system

Hi, i've been using rsync for about 3 years to keep common a set of shared applications on 40 linux boxes. No problems with it on redhat 6.2, but now I have about 4 redhat 7.3 boxes and the rest 7.2 and when I try to rsync the common directory I am getting 'unexpected tag 90' errors. the command I am running is: strace /usr/bin/rsync -e ${SSH} -avx --delete --exclude

Hi all, Please excuse the many posts. Wondering if any one can help me with the the setup. I have 2x2TBdisks. I would like to mirror them. I would like to create two LVMs so that I can snap shot from one to the other. During Centos 6 install, how would I go about this as its confusing? So far I am here; 1) Created the following raid devices; md0 500MB (use it for /boot) md1 4000MB (use it

Hi all, Taken from this link; https://www.centos.org/modules/newbb/print.php?form=1&topic_id=34988&forum=55&order=ASC&start=0 Seems like I am having the same issue. I assigned my boot loader to be on /dev/md0 rather then the default of /dev/sda1 Does any one have insight to this? Thanks in advance. BTW, I have no swap partition and will do a swap file instead, easier to

I have a p4 motherboard with 2 ide interfaces, I connect 2 40 GB drives as hda and hdc, I install Centos 4 from a CDROM, and partition the drives as 2 x raid partition each plus a swap partition on hda, the make md0 and md1 to install /boot and / respectively. Install goes well, everything looks great, go to reboot from drives, and all I get is "grub" but no boot. I have tried this ten

I have a system that is RAID -1 configured as /dev/md0 is /dev/hda1 /dev/hdb1 /dev/md1 is /dev/hdb3 /dev/hdb3 it seems as though /dev/hda has failed.... I have another disk (identical model) that I can replace hda with. I know about the commands fdisk to repartion and raidhotadd /dev/md0 /dev/hda1 and raidhotadd /dev/md1 /dev/hda3 (to be ran after the system boots). BUT... how do I now get

I have a CentOS 4.2 system that was set up VERY quickly following the demise of its former life as a CentOS 3 server - you don't want the full story, but it had to be done quickly to get a company up and working following a slight disaster involving an electrician, a portable appliance safety tester and a pulled power cable - anyway, here's where I am at... Everything is running fine but

Hi All, I'm currently trying to install centos 5.4 x86-64bit on a raid 1, so if one the 2 disks fails the server will still be available. i installed grub on /dev/sda using the advanced grub configuration option during the install. after the install is done i boot in linux rescue mode , chroot the filesystem and copy grub to both drives using: grub>root (hd0,0) grub>setup (hd0)

Hi, When I perform a software RAID 1 or RAID 5 installation on a LAN server with several hard disks, I wonder if GRUB already gets installed on each individual MBR, or if I have to do that manually. On CentOS 5.x and 6.x, this had to be done like this: # grub grub> device (hd0) /dev/sda grub> device (hd1) /dev/sdb grub> root (hd0,0) grub> setup (hd0) grub> root (hd1,0) grub>

Hello list, I'm trying to make sure that I'm performing a path analysis correctly using the sem package. the figure at http://flame.cs.dal.ca/~sstewart/regressDiag.png has a detailing of the model. The challenge I'm having is that reuse is an indicator (0/1) variable. Here's the code I'm using: corr =

Does anyone have a standard install of CentOS virtualization grub.conf working in a proven state with the FALLBACK option? If so, can you post your grub.conf? I mistakenly updated to 5.5 and am concerned about nvidia driver comments in the release notes. I did not have protectbase configured on this machine. It is a remote device that will reboot.

Hi- I am having a weird problem with setting dom0 kernel output to the serial console with Xen 3.0.4-1, below is my grub setting. With this setting if I don''t enter the grub menu and have the default boot to the first image, everything works fine and I can get output/input to the serial console. The problem is when I enter the grub menu and select the image to boot from, if I

Hi folks, I updates one of my long-running CentOS 4.x systems today, and afterwards it wouldn't boot properly. My issue was that it would start, then announce: Checking root filesystem /dev/md0 is mounted. e2fsck cannot continue. After much twiddling around, I discovered that if I booted from the first kernel I had, it would boot properly. Now this is a hand-rolled RAID, not an

Hi all, As part of my raid experience, I have yet to have to do this, but was wondering how you guys would attempt it. I have 3 drives in a raid 1, with one as a hot spare. They are 250gb with all space used by two raid devices, 1 with boot, the other with LVMs filling them up. Now, lets say down the road I want to put in 500gb drives and replace them....yikes. I was thinking of taking out the

Hi all, I'm trying to setup a RAID-1 with Centos4.2 on HP Netserver E60. The raid consists of 2 9,1GB SCSI disks. The partitioning and installation process went smoothly, but after it finished and rebooting, there is an error: Missing operating system. The partition is: / /home swap Bootloader is on device md0. What could be possibly wrong? Thank you, -- Fajar Priyanto | Reg'd Linux
