similar to: GRUB woes: GRUB Hard Disk Error

Since the "SELinux - way of the future or good idea but !!!" thread is deep in heated discussion, I decided not to derail to ask a simple question. I found this guide for SELinux: http://www.linux-books.us/centos_0005.php and it looks like it's straight out of RedHat. However, it's dated 2005. Will this be sufficient to help understand a CentOS 5 - or 6 - installation of

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

Hello: I've written a Grub Installation How-To, and I'd like to post at least a draft version. The information presently at http://wiki.centos.org/TipsAndTricks/InstallFromGRUB is somewhat related, but my How-To is much more detailed. The information at "Tips and Tricks: Installation Tips" is most closely related to what I prepared, so I suggest that a new page entitled

Hello, I'm using the latest CentOS with phpBB 3.0.x + postgreSQL + sendmail (relayed through gmail.com) - all those programs working fine, with no big modifications of the CentOS defaults (i.e. SELinux is on). Now I'm struggling with the seemingly simple problem, that when I put an .html file into /var/www/html/ then Apache won't serve it. In the browser I see: "Forbidden You

I have Windows 7 on /dev/sda and CentOS 6.4 on /dev/sdb. Here are the layouts: (parted) select /dev/sda Using /dev/sda (parted) print Model: ATA WDC WD10EZEX-00Z (scsi) Disk /dev/sda: 1000GB Sector size (logical/physical): 512B/4096B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 374MB 373MB primary ntfs boot

doing that grub-install /dev/sda will give me the "corresponding BIOS device" error. But now I fixed it by doing a manual grub install. first boot with cd1 and type linux rescue at the prompt when you're at the linux prompt after detecting and mounting the partitions, do a "chroot /mnt/sysimage" then # grub --batch #grub> root (hd0,0) Filesystem type is ext2fs,

Hello tincers, I was recently trying to add a new Windows client to my tinc network and ran into an interesting error; upon starting tinc I am met with the usual successful startup (debug level 0; detects TAP device; Ready), however it appears that any writes/reads from the TAP device fail with: "Error while writing to Windows tap device <device ID truncated>: (997) Overlapped I/O

I've got two pendrives. I want to install a Debian on them. RAID1. Ok... ... After I installed it in RAID1, it works perfectly, ok! :) When I pull out one of the pendrive [good pendrive], it still boots up, hurrah :) But: ... When I pull out the other pendrive [i plug in the first one i tried] it say's: GRUB hard disk error What can I do? I already tried: grub-install /dev/sdc

With Centos3, fedora1/2 I have been able to put /boot on a RAID1 partition and have it boot normally. Unlike earlier versions that used lilo as the default boot loader, these did not make the 2nd drive bootable but at least I was fairly confident that if the first drive failed I could use the install CD in rescue mode to fix up the 2nd one and go on. However, Centos4 won't boot at all with

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>

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

Hi, This must be a FAQ somewhere, although I am unable to find the answer quickly. We would like to have a bootable USB device offer the possibility to boot from the local disk. Unfortunately what happens when using 'chain.c32 hd1' is that GRUB works, but the GRUB configuration refers to it's disk as 'hd0', so booting an entry fails. One has to manually change 'root

Dear All, I'm trying to install Centos 4.2 x86_64 on a new Opteron server, using a software raid 1 boot partition. Here is the appropriate section of my kickstart.cfg #System bootloader configuration bootloader --location=mbr #Clear the Master Boot Record zerombr yes #Partition clearing information clearpart --all --initlabel #Disk partitioning information part raid.01 --size 50000

Hi, After upgrading my workstation to CentOS 7.5 (1804), I had to upgrade my kernel from vanilla to kernel-lt from ELRepo. My NVidia GeForce 210 would only work with the driver provided by NVidia, which in turn required a more recent kernel than 3.0.10. Anyway. Right now here's all the kernels that I have on my workstation: [root at alphamule:~] # rpm -qa | grep -i kernel

Hi all! Doing some tests with CentOS 5.5 on a KVM virtual machine, after doing the installation, I added a second disk. But when trying to boot from it, I get the following error: --------------------------------------------------------------------- root (hd1,0) Error 21: Selected disk does not exist --------------------------------------------------------------------- The two disks are

I hate to bother the list with this, but I am lost. With our servers that use LILO we use append=rootflags=data=journal. I have read everything I can find on GRUB, the key is everything I can find, and I have no idea how perform the same function in grub.conf Randy
