similar to: Centos 7 how to make second disk of RAID1 bootable

HI all, I just did a fresh C7 install using kickstart. fdisk -l /dev/sda shows: # Start End Size Type Name 1 2048 2050047 1000M EFI System EFI System Partition 2 2050048 104450047 48.8G Microsoft basic 3 104450048 112642047 3.9G Linux swap 4 112642048 234440703 58.1G Microsoft basic What extra do I need to

On earlier versions of Centos, I could boot the install CD in rescue mode, let it find and mount the installed system on the HD even when it was just one disk of RAID1 partitions (type=FD). When booting from the centos5 disk the attempt find the system gives a box that says 'You don't have any Linux partitions'. At the bottom of the screen there is something that says:

Hi, There was some problem with our system so I re-installed the server with CentOS 7. Now, when I am trying to run 'fdisk -l' command, it is returning a broken output. It throws this error- "fdisk: cannot open /dev/sdc: Input/output error". There are valid /dev/sdd and /dev/sde devices which are mounted and they are accessible but, somehow /dev/sdc is having a problem and

Greetings, until yesterday I was running a btrfs filesystem across two 2.0 TiB disks in RAID1 mode for both metadata and data without any problems. As space was getting short I wanted to extend the filesystem by two additional drives lying around, which both are 1.0 TiB in size. Knowing little about the btrfs RAID implementation I thought I had to switch to RAID10 mode, which I was told is

I am building a mailserver and with all the steps, I want to image the drive at various 'checkpoints' so I can go back and redo from a particular point. The image is currently only 4GB on a 120GB drive.

Hello, I have a question about margins when plotting an unrooted tree (type="unrooted") with the 'ape' package ver. 1.7. When I plot an unrooted tree with: no.margin=TRUE it seems that the margins are still there. It appears to be only when type="unrooted". I'm plotting multiple plots using layout() and would like to be able to get rid of the margins or if

Dear experienced R-users, I am having some probably trivial trouble estimating the confidence interval for the difference of two group means, with groups been of unequal sample size. I am using the "Bootstrap" package and the function "bcanon"(bcanon(x, nboot, theta, ...,alpha=c(0.025, 0.05, 0.1, 0.16, 0.84, 0.9, 0.95, 0.975)) for Nonparametric BCa confidence limits. The

That is perfectly true. I had a beautiful bug in the code .... Switching from python to C have some weird side-effect. Indenting is not enough, brackets are required.... So I pushed https://github.com/ErwanAliasr1/syslinux/commit/5a122d218553a6d4019273653ba9fad66d6ae79e with the fix. I tested it on my multi-disk system with success. I also changed the name of the function. 2016-07-17 8:21

Hi I got a very tricky problem when I tried to compile a C++ program which links to libRmath.so. The program itself had no problem, I can compile and run in my own linux machine where I compiled libRmath.so file and copied it to system directory (/usr/local/lib). Now I want to compile my program at another linux box where I don't have root privilege. That machine only has binary version of R,

Hello, today I wanted to remove one drive from raid1, and people at #btrfs advised me to use ''-dconvert=single'' before ''btrfs device delete''. I thought of adding ''-mconvert=dup'' too, but the kernel does not let me do that. It looks like ''dup'' is disallowed for an array of multiple devices. So, to go back to a single-drive

Hi, is it possible to convert a bootable raw hdd image including grub (originally created with grml-debootstrap) to a bootable iso somehow? Cheers, adrelanos

Hello List I have a Bootable USB stick that we use to Boot our servers and then install CentOS, PostgreSQL and our SW thru a Kickstart script. It works like a charm but now we are thinking of going Virtual and prepping Virtual CentOS servers under VMware ESXi. However, to have the same "Boot and Install" functionality I see no other solution than Booting a VMware machine from an ISO.
