Table: VXFEN driver error messages
Message | Explanation |
---|---|
Unable to register with coordinator disk with serial number: xxxx | This message appears when the vxfen driver is unable to register with one of the coordinator disks. The serial number of the coordinator disk that failed is displayed. |
Unable to register with a majority of the coordinator disks. Dropping out of cluster. | This message appears when the vxfen driver is unable to register with a majority of the coordinator disks. The problems with the coordinator disks must be cleared before fencing can be enabled. This message is preceded with the message "VXFEN: Unable to register with coordinator disk with serial number xxxx." |
There exists the potential for a preexisting split-brain. The coordinator disks list no nodes which are in the current membership. However, they, also list nodes which are not in the current membership. I/O Fencing Disabled! | This message appears when there is a preexisting split-brain in the cluster. In this case, the configuration of vxfen driver fails. Clear the split-brain before configuring vxfen driver. |
Unable to join running cluster since cluster is currently fencing a node out of the cluster | This message appears while configuring the vxfen driver, if there is a fencing race going on in the cluster. The vxfen driver can be configured by retrying after some time (after the cluster completes the fencing). |
