Making a network recovery from a tape recovery

[David Hawes-Johnson]

Hi,

Now I know that we can turn a network recovery into a tape recovery, but can we do it the other way around?

I have a tape that contains an image that has been rolled out over 56 D-class boxes in remote sites over the UK. What I want to do now is turn the tape into a network archive for disaster recovery.

Getting the tar file off the tape isn't the problem, but getting the right config files are. I have run a network recovery to get the config files from a box for test, and then killed off the network archive creation. So should replacing the incomplete tar archive with teh complete one from the tape work?

I know of no easy way to do what you want to do.

The only thing that comes to mind is, if you have a spare D box lying around, go ahead and install from your tape and then immediately do a make_net_recovery from that box to get your network image.

That's the easiest way that I can think of.

Yes, I have two spare D's but they aren't in the most accessible place, and aren't network connected. These are the machines that we used to burn the D class disk before distribution.

I was going to let the whole network archive build, but the network is not particularly fast and I don't want this to continue into the online day..

Good idea though, I might see if there are any networked D classes (hopefully on the same subnet!!)

You can do a dd of Ignite tape and place it to the archive directory and change the configuration files as required.

I've done a combination of the two idea to get this working.

I used two other networked D-class machines to run a make_net_recovery, this helps to create the config files, etc... and means to stupid syntax mistakes are made.

I've then copied the 0x... (/var/opt/ignite/clients) directory using the MAC of the server I actually want to ignite an d modified the files in the directory to point to the new server (hostname/ip addresses/etc).

I've then used the tar file dd'ed from the tape and placed this in the archives dir (/var/opt/ignite/recovery/archives) - ensuring that everything has the correct permissions (644 at the very least).

This works a treat, and means that I can create client directories for all the systems (/var/opt/ignite/clients) easily and use the same archives directory to save on space..

Cheers guys
