OS= CentOS 5.4, 64bit. I've always had great luck using dd to copy entire disks, and booting on other systems.? However, I'm having difficulty with a couple systems.? I boot using an install DVD so the OS disk is quiet, and dd to my target disk: # dd if=/dev/sda of=/dev/sdb bs=1024k /dev/sdb is the blank disk.? The disks are 2T.? After a few hours the operation is complete.? But when I

I have a disk that is flagging errors, attempting to rescue the data. I tried dd first - if gets about 117G of 320G disk and stops incrementing the save image any more. Now I'm trying ddrescue and it also stops about the same point Thoughts on how to continue past that point ? Thanks, Jerry

Hi team! At work I have several small branch offices with ~5 PCs each. All PCs are member of a Samba4 domain, whose DCs are on the headquarters (linked by consumer grade VPNs) I want to ship "some small, cheap, reliable and magical device" to each branch, in order to provide just 2 things: * AD replication * File shares That't it, period. Nothing fancy. Suggestions??? What do you

Hi All, I downloaded: http://mirror.centos.org/altarch/7/isos/armhfp/ for the PI3 This article says the PI3 runs X. http://news.softpedia.com/news/centos-7-linux-officially-released-for-raspberry-pi-2-banana-pi-and-cubietruck-497891.shtml When I groupinstall Gnome desktop and reboot, then run startx I get an error about no screens found. Whats the trick to get X on the PI3? Thanks, Jerry

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

Is there a good guide for setting up a Samba active domain controller? I am currently running ClearOS, but it does more than what I want, even that I had to modify to suit my needs. Only a few systems. Currently still XP, but I will migrate to Win7 with this move. Of course I will be doing the install on a Cubietruck armv7. thanks for any pointers.
