[gpfsug-discuss] Odd networking/name resolution issue

[TURNER Aaron]

Dear All,

We are getting, on an intermittent basis with currently no obvious pattern, an issue with GPFS nodes reporting rejecting nodes of the form:

nodename.domain.domain.domain....

DNS resolution using the standard command-line tools of the IP address present in the logs does not repeat the domain, and so far it seems isolated to GPFS.

Ultimately the nodes are rejected as not responding on the network.

Has anyone seen this sort of behaviour before?

Regards

Aaron Turner
