WebA1. Export the GPFS filesystem using NFS. Edit /etc/exports and add an entry to export the GPFS filesystem to the network of the Bright Cluster: /gpfs1/test WebThe issue occurs when you loose link on one of the two cNFS interfaces on a cNFS server with two cNFS interfaces. cNFS goes in a failover->failback->failover->failback loop forever. I've tested this behavior on two totally different GPFS clusters (3.5.0.11 and 3.5.0.13) with similar configurations.

WebCNFS network setup In addition to one set of IP addresses for the GPFS cluster, a separate set of one or more IP addresses is required for CNFS serving. CNFS setup You can set up a clustered NFS environment within a GPFS cluster. CNFS administration There are some common CNFS administration tasks in this topic along with a sample configuration. WebNFS failover. As part of GPFS™ recovery, the CNFS cluster failover mechanism is invoked. It transfers the NFS serving load that was served by the failing node to another node in the CNFS cluster. Failover is done using recovery groups to help choose the preferred node for takeover. The failover mechanism is based on IP address failover. chilton manor farm

Ensure that you are the only person who is doing the work! check gpfslogs (first on cluster manager, then on FS manager, then on NSD servers) check syslog (/var/log/messages) for eventual errors. grade rods fiberglass 10ths
