Subject says it. I would like to find out if I have anything written on the MBR of a disk in my system /dev/sda, or any other device. If there is something there, is it readable, or recognizable to humans? thanks, -chuck

Hi all, I used a kickstart script to setup a new machine of mine with RAID 1 (I couldn't get anaconda to create matching partition schemes). So I've now got /dev/sdg1 and /dev/sdh1 as 'bios_grub' (/dev/sd{a-f} are a separate array). 0 root at an-nas02:~# parted /dev/sdg print free Model: ATA ST3000NC000 (scsi) Disk /dev/sdg: 3001GB Sector size (logical/physical):

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

I don't know if this additional information helps. Looking at he efibootmgr output, is the centos entry pointing to the right place? Also, any idea why the update isn't being make permenant?

I am experimenting with KVM and I wish to create a virtual machine image in a logical volume. I can create the new lv without problem but when I go to format its file system then I get these warnings: Warning: WARNING: the kernel failed to re-read the partition table on /dev/sda (Device or resource busy). As a result, it may not reflect all of your changes until after reboot. Warning: Unable to

I'm hoping that someone here can help. 1: Is this system booting UEFI or BIOS? 2: Is the disk partitioned with MBR or GPT? 3: Is /boot on its own partition? 3TB drives are larger than MBR and BIOS properly support, so they're only really expected to work on a system partitioned with

Hi Jim, Thanks for this. I looked into what you said, and once happy I ran the command you gave. It appeared to work as it did not come up with any errors, and the output from efibootmgr showed 1) Centos had been added as an option and 2) it was the first in the boot sequence. However, when I rebooted the laptop went straight into Win8, and after rebooting back into KDE Live, the option is

On a headless C7 server (actually a pogoplug with the Redsleeve 7 distro), I have a usb attached backup drive (what other type of drives can you have on a pogoplug other than usb? :) ). I had reformated the partition as ext4: # parted /dev/sdb print Model: WD My Book 1230 (scsi) Disk /dev/sdb: 3001GB Sector size (logical/physical): 4096B/4096B Partition Table: msdos Disk Flags: Number Start

While researching another issue unrelated to Syslinux, I found some mildly disturbing news that affects Syslinux. As HPA stated back on 2009-06-04, hard drive manufacturers are pushing towards a 4096B (4kiB; 4k) native sector size. They're calling it "Advanced Format Technology". It appears that WD (Western Digital; WDC) is the first with some products being released back in

I have 4 ST2000DL003-9VT166 (2Tbyte) disks in a RAID 5 array. Because of the size I built them as a GPT partitioned disk. They were originally built on a CentOS 5.x machine but more recently plugged into a CentOS 6.2 machine where they were detected just fine e.g. % parted /dev/sdj print Model: ATA ST2000DL003-9VT1 (scsi) Disk /dev/sdj: 2000GB Sector size (logical/physical): 512B/512B

Results for parted: parted /dev/sda print Model: ATA KINGSTON SUV5001 (scsi) Disk /dev/sda: 120GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 1049kB 1050MB 1049MB fat32 EFI System Partition boot 2 1050MB 53.5GB 52.4GB ext4 3 53.5GB 57.7GB 4194MB

Hi I have reinstall Fedora 20 from distrib. I have run yum update and yum upgrade. Running kernel is : 3.14.7-200.fc20.x86_64 Installed Libvirt packages are: libvirt-client-1.1.3.5-2.fc20.x86_64 libvirt-daemon-1.1.3.5-2.fc20.x86_64 libvirt-daemon-config-network-1.1.3.5-2.fc20.x86_64 libvirt-daemon-driver-interface-1.1.3.5-2.fc20.x86_64 libvirt-daemon-driver-network-1.1.3.5-2.fc20.x86_64

we have DELL server with Centos 5.3 X86_64 bits version on it. This server also have couple MD1000 connect to it. We configured MD1000 as one hardware Volume size 2990GB. I tried to use "fdisk" to partition this 2990Gb volume and "fdisk" can only see 2000GB. does 64 bits O.S. still have 2TB limitation on File system? Does there has other tool can partition disk size large

Hey! I have a strange condition in one of the servers that I don't where to start looking. I login to the server via SSH (cant doit any other way) and anything that I type is slow HTTP sessions timeout waiting for screen redraw. So, the server is acting "slow". server is bare metal. no virtual services. no alarms in the disk raid note: server was restarted because of power failure.
