OK todays problem. I have a HP N54L Microserver running centos 6.5. In this box I have a 3x2TB disk raid 5 array, which I am in the process of extending to a 4x2TB raid 5 array. I've added the new disk --> mdadm --add /dev/md0 /dev/sdb And grown the array --> mdadm --grow /dev/md0 --raid-devices=4 Now the problem the resync speed is v slow, it refuses to rise above 5MB, in general

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

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

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'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 all, On a F18, I installed livecd-tools-18.15-1 I downloaded CenOS6.x minimal .iso and with livecd-iso-to-disk the resulting USB is never bootable: the computer doesnt boot on it. Tested on many computers. The fact is I succeded to install CentOS on a Netbook (no CD/DVD tray), but I dont remember how I invoked livecd-iso-to-disk. I tried with many combinations (/dev/sdc is the USB

Hi, I have to do some maintenance on a CentOS 7 proxy installed on a routerboard without a video card. The only way to access this machine directly is via Minicom and serial port. I'm using NetworkManager TUI (nmtui) to configure network interfaces, but Ncurses rendering in Minicom works in the sense that chickens fly and horses swim. What you get is a forest of question marks with a few

Dear R user, if the dates are in format as "20050425" i.e., Apr. 25 2004" can you suggest an easy way to transfom it to standard form as "2005-04-25" or "2004Apr25" or "2005/04/25" or any other format which is R recognizable? if there is no easy way to do that, can you let me know what is the function in R performing similiar function as the

Has anyone seen any attempts to give Markdown a PEG (parsing expressions grammar) recognizable by some ruby PEG parser generator grammar like Treetop? http://treetop.rubyforge.org/

Hi, I have researched batch mode for windows and could not find anything that worked. I know the code should be $ R CMD BATCH inputfile.R outputfile.Rout or R <inputfile.R > outputfile.Rout I tried these without success. I need detailed, step by step instructions on how to do this. I have tried typing C:\R\bin\x64\Rgui.exe before it, but this just opens R. When I tried to do this, it

How do you resize the partition without loosing data? gparted does not support LVM.

Hi: When debugging some floating point assembly, we found it is inconvenient to read the decimal constants in assembly. In hex form many FP numbers are immediately recognizable, their exponents are more obvious etc. We normally use hex form in debugger or LLVM IR, not sure what is the reason that we want to use decimal in assembly? The form change won't change precision or affecting

Hi, I'm working on writing a FLAC encoding plugin for a personal cd ripping project of mine which uses paranoia for the raw audio extraction. My basic setup which follows gets me oddly high pitched audio with lots of noise (although the music IS somewhat recognizable). #include <FLAC/stream_encoder.h> FLAC__StreamEncoder *encoder; FILE *output_file_descriptor; encoder =

Hi, I tried using lldb built from master, but still seeing some STL container member functions not recognizable in a debugging session. I am wondering if the work has been pushed to master; also if it's pushed but not enabled by default yet, is there a flag I can use to turn on the expression evaluator using Clang modules. Thanks a lot for the great work. Best Regards, Jiading

FWIW, I've got a powershell script that builds an exports.def file for recognizable C functions. You could adapt it to Python and make it part of the official build if the LLVM community thinks it will be beneficial to have libLLVM.dll The script is located here: https://github.com/mjsabby/LLVMSharp/blob/master/GenLLVMDLL.ps1 On Wed, Apr 1, 2015 at 9:03 AM, Reid Kleckner <rnk at
