Is it possible to create an image that when installed skips over some
drives on the cloned machine?
More detail...
I have been using systemimager successfully with cluster's of machines
where I can overwrite all data on all drives of the cluster nodes. But
recently I needed to work with a cluster that has data that needs to
remain in place on one of the drives on the nodes. This is because the
cluster will be dual booting with WinXP on one drive and Linux on the
other. (yes, I know I am asking for trouble but I really need to do it).
My setup is:
- /dev/sda - WinXP (must not be overwritten)
- /dev/sdb - Linux
I want to use systemimager to manage the Linux drive for all the nodes
and ignore WinXP.
At first I saw the new option (to me anyway) of --exclude that can be
passed to si_prepareclient. It seemed appropriate since the docs say
"Do not gather partition information for DISK(s). The result of using
this option, is that DISK(s) will not be partitioned during the
auto-install process.". Unfortunately what this really means is ignore
the drives when making the image and then map the drives from the golden
client to the clones based on disk order. For example, when I used
--exclude /dev/sda on my system it did ignore the drive, but then when
setting up the clone the contents (partitions, data, etc) from the
golden client's /dev/sdb got installed onto the clones /dev/sda.
Unfortunately I lost a windows drive learning this, but that is part of
the fun of doing this type of thing right. :)
So I am looking for other ideas. One idea I have yet to try is to
reorder the drives in all the systems so sda is the Linux drive and sdb
is the WinXP drive. Then I could probably use --exclude /dev/sdb to
ignore the windows drive like I tried above but then when it maps the
drives for installation it will still get the correct drive.
For right now I am just manually editing the autoinstall scripts. Not a
great solution but it may work for a while.
If anyone has another idea please let me know.
Thanks,
Allen
