[Server-devel] Cloning

[David Leeming]

Hi Martin

We had some results doing this , but it is actually much more time consuming
than installing and configuring the servers individually. What would be
really useful is (a) some way of automatic this or (b) the ability to export
the XS configuration especially the Moodle settings.

Hi David,

super brief -

- get the machine in 'single user mode' ("init 1" on the commandline will
work)
- plug new disk in, setup the partition table, and the filesystems
- rsync / and /library to the temp mountpoints
- remove hardware-specific files: /etc/udev/rules.d/70-persisntent-net.rules
- fixup /etc/fstab to match the UID of the new filesystems
- run grub targetting the new disk
- move new disk to new machine

that will _clone_ the XS so it will keep a lot of identifiers (and all
the data) from the original XS.

Do NOT use this technique for "cloning a base install". Use
kickstart/anaconda methods to automate many-machine rollouts.

cheers,


martin
