Move linux to another hard drive (dump, restore, backup)

by

There are several methods to move running Linux to another hard drive at the same server. But I used Unix dump/restore utility to perform this… First of all it’s necessary to partition new hard drive in the same way as it’s done with old drive (Linux is running at). I usually use ‘fdisk’ utility. Let’s assume that old drive is /dev/hda and new one is /dev/hdb. To view hda’s partition table please run ‘fdisk -l /dev/hda’ which should show something like this: Disk /dev/hda: 60.0 … Read more

How to create custom linux ISO image?

by

It’s rather trivial task to make some changes into already burned installation or live CD. It may be performed to add some files to this CD or edit files on it. In any case it’s impossible to loop mount .iso file and then save it as iso9660 filesystem is read-only. So, just mount your CD or iso image to some directory by commands: sudo mkdir /mnt/image sudo mount /dev/cdrom /mnt/image or sudo mount /path/to/your.iso /mnt/image -o loop then copy it’s contents to some directory: mkdir … Read more

Source: server running rather obsolete Fedora Core 1 with Apache, sendmail, ftp and other stuff. Target: any Linux server with at least one hard drive of appropriate disk space installed (in this case target server was running Knoppix). Third server: any ssh running system. First of all it’s necessary to get all servers to be accessible to each other via ssh. Read your distribution’s manual to find out how to achieve it. There are several possible ways to move Linux to another server by means … Read more
