Do U know If I can clone a server using baremetal??
here we use something like a cluster (MS Load balancing) there is 3 computer with the same MAC, and exactely the same hardware, that 3 servers create an unique IP and all of them respond that. I wanna clone one of these servers to put another one in productioin just changing some configurations.
The dd method alows to restore on different hardware as well, in that case
for windows it will require you to reboot one or more times (new hardware found and reboot system, [after loading new drivers])!
for Linux users you have to go in for rescue mode make initrd for new hardware/SCSI Disk, install/fix boot loader and go with new hardware.
The dd+ssh method allows to create replica/close of any size. This is piped input-output.
The dd+gzip is greate and efficient with any other software product: you can create very small size BareMatel image. I usually do like this for my servers in SAN where disk size runs in hundreds of GB:
First you boot with LinuxLive CD or go in rescue mode, 2) mount the filesystem on some point in RW. create a file in the mounted filesystem like
wait to finish this, since it will take lot of time to fill up the blank space your file system. This is writing a stream of zeros. This is tricky. When you will compress your filesystem (or Linux Device) the whole of the blank space will become ZERO SIZE! (here commercial product lack the performance) AND the rest of the file system will become to less than 1/3 of the occupied by files.
For example, a full Linux/windows system with OS/RDBMS (except data), with 36GB drive results a compressed image of 3GB size.
Hi Zahid thanks for your tutorial, do you know how much space the BMR Server image takes up? Just wondering if it can be broken down to 1Gb for example per server.
i also have some other articles which you all guys may like. i am adding my article links for all of you. Hopefully i may be good. i tried my best for all you guys help.
