clone(2) 30-sec delay in apache

I’ve issue with apache. Everything begins about a week ago (so this may be related to latest system updates) – my monitoring tools SMS me about non-working website. I’ve checked it, and looks like request to trivial cgi (implemented in perl) took 30 seconds. After restarting apache problem was fixed for next few hours/days, and then happens again. Initially I suspect php, because it was only update (5.3.15->5.3.18) which may affect apache. I’ve tried to […]

Alternate way to create a clone of a UNIX System

THE STORY: (If you don’t like to read much, down below is the question ) Where I work we have two HP RP2470 servers same hardware same number of hard drives same everything :). One of them is a production server and runs HP-UX 11.00. The poor ba***rd hasn’t been turned off for years and now I have to make a clone of it on the other server – just in case, for redundancy. The […]

large (30+ at a time) scale cloning of hard disks

I know that it is possible in *nix to clone a hard disk within a machine using DD if=/dev/hda of=/dev/hdb I am wondering if something similar could be accomplished over a LAN (assuming a decent gigabit switch) with BitTorrent. Would it be possible to use a “master” with a torrent tracker like Vuze to make a .torrent from the /dev/hda in one box, and then boot multiple other boxes on the LAN from a knoppix […]

Clone CentOS 6.0 Unique identifiers

when cloning CentOS (minimal install + nginx, tomcat, postgres all not running) in a VMware virtual environment what unique identifiers are present on the cloned machine? The information I have found so far is that when cloning, the new MAC address causes an a new interface to be added, so it is necessary to follow instructions here: That is, remove the 70-persistent-net.rules and update the MAC address in /etc/sysconfig/networking-scripts/ifcfg-eth* But, is there any other unique […]

Partition size inconsistency after dd clone

We have recently upgraded a system HDD – it was 160GB, now 2TB. We upgraded as we were running low on space, mainly on /usr, and also on /home. I prepared the new drive with a Live CD and GParted (and made some partitions larger). Then I cloned /, /usr, and /boot to the new drive using dd. The partition size of /usr on the old drive was 23GB, but I made it ~50GB on […]

SSH/Git: Specify paths with hostname instead of IP

Alright, quick question. When SSHing to a server using the IP, I can also specify a path to use, such as: git clone ssh://git@127.0.0.1:/home/git/project.git SomeProject However, when using a hostname, the command thinks the path is part of the host name: git clone ssh://git@localhost.com:/home/git/project.git SomeProject Which yields an error about the : before the path ssh: localhost.com:: no address associated with name (Yes, I am aware that I cannot SSH into localhost.com) Is there a […]

Cloning a linux system from sdx to cciss

I have an HP ML 310 server running CentOS Linux 5.5. I’m buying a RAID card (LSI 9260-8i) to set up a mirrored OS drive. Right now, the boot drive is set up with GRUB installed on the MBR of /dev/sda & has a 100MB /boot partition for /dev/sda1, then the rest is configured in LVM with a 20GB with a 20GB VG for the root partition & ~80GB VG for home. The new disk […]

Cloning old RHEL 4.3 on Dell Poweredge 2850 to PE2950 with SAS PERC6i

I have a Dell PowerEdge 2850 with a PERC 4 controller and SCSI drives. I need to clone that to a PE2950 with a PERC6i with SAS drives. I’ve used the DKMS package along with the latest driver on Dells website to create a driver disk and successfully installed by hand so I know that it will install but I need a good suggestion for cloning options. I’ve tried clonezilla but it does not recognize […]

What’s the easiest way to clone a production virtual machine for testing?

We’re running Hyper-V on Windows Server 2008. I have a production environment VM for which I’m planning some major application upgrades. These upgrades are completely within the VM (not at the host level) and are not related to the OS. I’d like to clone the production VM so I can test the upgrade procedure without affecting active users. So my questions are: what’s the easiest way to clone the production machine? When I do the […]
