similar to: A puzzle with grub-install

Hello Everyone I have a remote CentOS 6.4 server (with KVM access), when I received the server it was running with LVM on single disk (sda) I managed to remove LVM and install raid 1 in sda and sdb disks the mirroring is working fine, my only issue now is that everytime I reboot the server I got the grub command line and I have manually boot using comand grub> configfile

I'm playing with software RAID and LVM in some virtual machines and I've run into an issue that I can't find a good answer to in the docs. I have the following RAID setup: md0: sda1 and sdb1, RAID 1. This is /boot md1: sda2 and sdb2, RAID 1. This is a PV for LVM. VolGroup00, this is the volume group and md1 is the only PV in it. LogVol00 is swap LogVol01 is / LogVol02 is /home

Greetings - The short story is that got my new install completed with the partitioning I wanted and using software raid, but after a reboot I ended up with a grub prompt, and do not appear to have a grub.cfg file. So here is a little history of how I got here, because I know in order for anyone to help me they would subsequently ask for this information. So this post is a little long, but

Hello, I have two disks sda and sdb. One of the was broken so I have changed the broken disk with a working one. I started the server in rescue mode, and created the partional table, and added all the partitions to the software raid. *I have added the partitions to the RAID, and reboot.* # mdadm /dev/md0 --add /dev/sdb1 # mdadm /dev/md1 --add /dev/sdb2 # mdadm /dev/md2 --add /dev/sdb3 # mdadm

I'm experimenting with how to attach storage to a guest virtual machine (I sent another message to th elist about that as it's slightly different) Looking in the XML files for my virtual machine, I see this: <disk type='file' device='disk'> <driver name='qemu' type='qcow2'/> <source file='/vm/myvm/tmpeuiVc9.qcow2'/>

I am attempting to get multipath working with device-mapper (CentOS 4.2 and 4.3). It works on EVERY install of mine from RH (also v4.2, 4.3), but the same multipath.conf imported to all my installs of CentOS do not work. Note that I have tested a working 4.2 configuration file from RH on CentOS 4.2 and a working 4.3 configuration (it changed slightly) on CentOS 4.3. Neither worked. Our production

Hi list, I'm new with UEFI and GPT. For several years I've used MBR partition table. I've installed my system on software raid1 (mdadm) using md0(sda1,sdb1) for swap, md1(sda2, sdb2) for /, md2 (sda3,sdb3) for /home. From several how-to concerning raid1 installation, I must put each partition on a different md devices. I've asked times ago if it's more correct create the

Hi, I see some strange and dangerous things happening on a HPE server with HPE Smart Array controller where EL9 ends up with wrong device nodes/symlinks to the attached disks/raid volumes: (I didn't touch anything here but at 08:09 some symlinks were changed) /dev/disk/by-id/: lrwxrwxrwx 1 root root 9 Mar 1 07:57 scsi-0HP_LOGICAL_VOLUME_00000000 -> ../../sdc lrwxrwxrwx 1 root root 10

Earlier this evening, I had the interesting experience of shutting down my machine (because of that lp out-of-sync problem, discussed elsewhere), and watching it not come back up. I admit that I changed out one of my DVD writers for another one, but I don't understand how that could have had any effect on this: When I restarted the machine, it came up to the point where it normally shows:

Hello everyone. I'm trying to install CentOS 8 with root and swap partitions on software raid. The plan is: - create md0 raid level 1 with 2 hard drives: /dev/sda and /dev/sdb, using Linux Rscue CD, - install CentOS 8 with Virtual Box on my laptop, - rsync CentOS 8 root partition on /dev/md0p1, - chroot in CentOS 8 root partition, - configure /etc/mdadm.conf, grub.cfg, initramfs, install

Basically the issue comes down to my Volume Groups not being found by this initrd, causing good ole kernel panic. initrd-2.6.12.6-xen3_12.1_rhel4.1.img [root@xen01 lvm]# uname -a Linux xen01.inside.***.com 2.6.9-22.0.2.ELsmp #1 SMP Thu Jan 5 17:13:01 EST 2006 i686 i686 i386 GNU/Linux [root@xen01 lvm]# cat /etc/redhat-release Red Hat Enterprise Linux ES release 4 (Nahant Update 2) Everything

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)

I have followed the procedure on the Centos page: http://wiki.centos.org/HowTos/CentOS5ConvertToRAID My setup is slightly different. I am using two partitions, / and /home. I have setup swap as a file, /home/swapfile. My hard drives are 500Gig sda and sdb. In modifying the instructions for initializing sdb I have: used /dev/md0 for / (sdb1) used /dev/md1 for /home (sdb2) In section 3.6 The

I have a 1.5TB internal disk on my server. I partitioned this with fdisk, and CentOS-5.6 runs perfectly on it. But fdisk gives a very strange report. Here is the perfectly normal response to mount: ----------------------------- /dev/sdb10 on / type ext3 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) /dev/sdb2 on /boot type ext3
