I tested OpenSSI recently in a VMware-environment (3 virtual nodes), and found
it a very nice solution for my home-network (where I run some older PCs), especially
the "feature", that I have to install and maintain only one OS, and the transparency of
esp. the device files over the network. (I hope, I can use my scanners, which are connected
on one PC, anywhere in the network ;-)).
My Home-Configuration shall be one Initnode (which also runs the services DNS, WWW, Mail etc.
for the home net, and which has a DSL line to the internet), some cluster-nodes in the
internal net, and additional some none-cluster-members (like Windows-PCs), also in the
So I tried to install Debin 3.1 and openSSI on my Initnode, and run into some problems.
First there was the problem, that a debian-network installation didn't like the DSL-connect
to the internet. But I managed that somehow ...
Then I followed the paper "Installing an OpenSSI Cluster on Debian 3.1", where I think
there are some errors in it:
- it says "Install Debian testing (3.1) ...", maybe "stable" is better?
- the suggested entries in /etc/apt/sources.list didn't work (there is no
http://ftp.easynet.fr/openssi/openssi-v2 only http://ftp.easynet.fr/openssi)
- then I entered blank lines into the preferences file, and I got errors when
calling "apt-get dist-upgrade", so I removed that file, and ended up in a
totally messed installation ;-). Ok, next try ...
Now, I have the problem, that not all of my cluster nodes are i686 machines (I have also
a K6 ...), so I have to compile the kernel by myself.
Question: is it enough to change the content of /cluster/kernel_version, so that ssi-ksync
later will work as expected?
The next problem is, that I find the network configuration a bit confusing.
I want to run the cluster with addresses 192.168.87.X, and the non-cluster home-network
with 192.168.98.X, the CVIP of my cluster shall be on the home-network.
How can I add additional routes to the cluster-interfaces and routes with the CVIP
as gateway? And what do I have to configure to see the CVIP on the non-initnodes?
In my test-VMware-environment I failed to configure that ...
When the cluster runs, then I will run X on some nodes, maybe additional questions
occur then ;-)
But a question: what is the format of /etc/rc.nodeinfo? (I think, that is the file,
which says, what services should be started on which nodes. Am I right?)
And a last question for now: Is there somewhere a short description, what to do,
when I want to run a laptop as cluster-node with a PCMCIA-WLAN-card?
So for now, what I have seen in my test-cluster, openSSI is great work (and my
problems, which I mentioned above, should be no real hard problems....)
Best regards, and merry solstice and a happy new year, Robert
