I'm going to guess that there are no IDE drives that have 4096 byte physical sectors, but it's worth confirming you don't have such a drive because the current partition scheme you've posted would be sub-optimal if it does have 4096

- Ahh OK now I see why I was confused. The originally posted partition map uses cylinders as units, not LBA. I missed that. Cylinder 1 is the same as LBA 63. And that is sufficiently large for a GRUB legacy stage 2. - OK this is screwy. Partitions 1 and 3 on both drives have the same number of sectors, but partitions 2 differ: /dev/hde2 401,625 975,691,709 975,290,085 fd Linux

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

Dumb thought: I don't remember how, other than from a grub menu, but I'm pretty sure there's a way to default boot into a grub shell. Once there, you can see, using file completion, the drives, and where your initrd is. mark

If I have a system with two disks, where device.map labels one as hd0 and the other as hd1, and I swap those numbers, the resulting boot sector will differ by one bit.

Hi, This morning one of my servers (centos 4.5) refused to boot. The console shows a lopp message grub loading stage2... I've been able to boot from the install CD choosing the rescue option. I can chroot /mnt/sysimage with no problems and even started the services (network, mysql , httpd etc). How can I solve this? I've followed the manual (

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

hi! raid 1 arrays: I already have 2 systems running this same raid1 config. 1 sys has 2 120 gb 1 sys has 1 120gb and 1 200gb but matching the raid partitions this system here that is giving me fits right now has 1 250gb and 1 200gb. I tried it w/a new 250 gb for the 2nd drive but the same results. Will not boot. in druid, when I am config. the raid arrays, I always create the boot partitions

Hello, I know that this card has support in FreeBSD but I'm curious if anyone has used them under heavy load in a RAID-5 configuration. We're thinking of equipping two of these cards with 8 120GB Hitachi drives and run it in an RAID-5 array for video material. The usual data streams will likely be 2-3 streams at about 5-20MB/s (totally) and I know that a single drive will handle that,

I never thought I'd say this, but I think it's easier to do this with GRUB 2. Anyway I did an installation to raid1's in CentOS 6's installer, which still uses GRUB legacy. I tested removing each of the two devices and it still boots. These are the commands in its log: : Running... ['/sbin/grub-install', '--just-copy'] : Running... ['/sbin/grub',

Please, download this. http://sourceforge.net/projects/bootinfoscript/ Run it: http://bootinfoscript.sourceforge.net/ Post a URL to the resulting file somewhere. I suggest having the entire computer assembled as it should be in normal use, rather than simulating device failure by removing a device. --- Chris Murphy

We're doing a "mini-RC3" to encourage testing of the Highpoint driver (hptrr) backout. Testing of 7.0-RC2 showed there were problems with the driver update done between RC1 and RC2. Because it's a "mini-RC" targetted at testing of one particular thing we have not bothered with setting up FreeBSD Update. You can use the normal cvsup-and-build method of doing an update

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
