Cluster wont form with only 1 node.

[Peter Scott]

I have built a 2 node cluster and have come across a couple of annoying problems I can't get to the bottom of.

First, when one node fails, the second node attempts to reform the cluster, but waits for the first node to come back up before reforming the cluster. I know this must be something really obvious, but I just can't see what.

Second, on one occasion a node failed, and this forced a TOC on the second server. This has only happened once, and the NODE_FAIL_FAST_ENABLED and SERVICE_FAIL_FAST_ENABLED parameters are set to NO.

Hi,

1. is the cluster lock disk accesable to the second node?
the NODE_TIMEOUT can be found in the cluster ascii file.

2. I guess you try to say if a package fails. This can couse a node to fail if the package software generates a panic without the intervention of the cluster deamon.

Hi,

Check for messages from cmcld in syslog.log to see if it gives any reasons/help for why the cluster won't form with only one node.

If there was a race for the cluster lock, the node which fails to get it will TOC, so as mentioned before, can both nodes see the cluster lock disk ?

Hi Peter,

How about the cluster lock disk. Are you using one and is it configured properly. In a two node cluster, if one node fails the second node takes hold of the cluster lock disk and will form a cluster. Look into the syslog.log file and see what happens when one node fails.

Hope this helps.
