Clustering

So we’re trying to get Sun Cluster 3.1 failing over an instance of M-Vault (our X.500/LDAP server) between two Solaris 10 (x86) machines. If you recall I mentioned way back when that we’d added SMF support so we were good Solaris citizens…

But it doesn’t work. Run the start script by hand, which pretty much just does a svcadm enable eddy and it works. The stop script does what you might expect, and also works.

Copious debug-by-printfs later, we decide that the cluster manager’s starting & stopping the server several times, not involving the probe command, and then just giving up.

A little googling… Ah, how to use Sun Cluster 3.1 with a service managed by SMF is mentioned in the clustering release notes. Click link. Here we go. To do that:

1. Don’t use SMF.
2. …

Round objects.

But apparently Cluster 3.2 integrates heavily with SMF, so our work wasn’t wasted
