Hi folks. I have a box running Uduntu 11.10 server. I have a new box running nothing but with a pair of identical disks that I want to run as RAID 1 (mirrored). My problem is that I want the new box to be running exactly what is running on the old box. What I want to do is configure the RAID array in the new box, then copy absolutely everything across to the new box such that reinstalling/reconfiguring anything is not needed. I suspect this is quite straightforward, albeit laden with pitfalls. Does anyone know of a document containg the ins, outs, ups and downs of this process. Thankies Simon.
Raid runs at the hardware level so you don't need to do anything special, just configure your new box like you want then copy across the files and you're done.
True, if you have RAID hardware. I don't so, therefore, it's a software RAID done using the built-in OS functionality. Hence my question.
I'd create an image of the hard drive (e.g. with CloneZilla, dd, etc.) and copy it to the new system. You can then set up software RAID, e.g. like this: non-LVM system: http://www.howtoforge.com/how-to-se...ystem-incl-grub2-configuration-debian-squeeze LVM system: http://www.howtoforge.com/how-to-se...ystem-incl-grub2-configuration-debian-squeeze
