So, it installed happily. Then wouldn't boot. No problem, I'll bring it up with pxe, then chroot and grub2-install. Um, nope. I edited the device map from hd0 and hd1 being the RAID to /dev/sda and /dev/sdb, then ran grup2-install. It now tells me can't identify the filesystem on hd0, and can't perform a safety check, and gives up. What am I missing? Google is not giving me any

Hello, I have installed the Xen 4.1.1 and a working kernel 2.6.32.43 which supports Xen on a Ubuntu Linux 10.04 LTS. However, I have never successfully booted the Hypervisor and Dom0. The screen is always black after some kernel messages rapidly go by. I think that I may pass the wrong parameters to the kernel or Hypervisor with GRUB2. Can any one share his/her working grub.cfg for GRUB2 with

Hi messmer, seems that anaconda supports partitioned RAID devices. Disk selection see one mdraid device and permits to create partition on it.

Hi All, I have a Dell R710 that has 6x1TB in a RAID-5 configuration. When installing CentOS 7 using the full disk capacity and booting in UEFI mode the machine dumps me into a GRUB rescue mode prompt. error: disk `,gpt2' not found Entering rescue mode... grub rescue> If I use the PERC RAID controller to make the disk smaller ROOTDISK volume of 100GB in size and then a DATA volume

That module should be available.

Dear All: I am having trouble trying to dual-boot VMware and Linux, and I tried everything I could come up with. The situation is that /dev/sda is fully used by VMware and /dev/sdb is used by Linux. VMware uses Syslinux, so I thought this would be simple... However, it is not. The bootable FAT partition is too smal to have kernels in it. As a fallback I tried to chain-load GRUB, but that did not

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>

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

I am running rsync throuhg cygwin and trying to "mirror" two hard drives (hd1 -> hd2). HD1 have tons of hard links (I will say about 2 millions) because I do monthly backups and have about 13 folders and maybe about 150,000 files. Every month when I make a new snapshot I would also want to mirror HD1 to HD2. I tried running rsync -aH --progress -vv /cygdrive/d/ /cygdrive/e/ I though

I just updated a server that's running CentOS 7. I do have elrepo enabled, because this Rave computer has four early Tesla cards. It won't boot. Nor can I get it to boot with either of the other two kernels, and I'll be the one that worked was erased. *Once* it complained that it couldn't fsck the large filesystem (IIRC, it's XFS). The other four-five times, I get pNFS

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 a laptop with windows 10. I went into the Windows disk manager and shrunk the volume to make room for C7. That worked. I also changed the BIOS from secure boot to "both" (secure/legacy) I installed C7, went fine. About the time it was done I realized I never saw anything about "other" boot options (seems I saw that in the past). Anyway sure enough, got done and C7
