Using majority-based fencing
For Flexible Storage Sharing (FSS), only majority-based fencing is supported. Majority-based fencing does not require configuring a coordinator pool or coordinator disks. Enabling I/O fencing configures majority-based fencing if no shared disks are present.
Note:
Enabling or disabling I/O fencing causes a disruption of Veritas Access services. When I/O fencing is enabled or disabled, some services such as NFS shares, CIFS shares, and S3 shares have to be stopped as the process of enabling or disabling fencing halts the VCS and cluster services. If any I/O is going on, then the cluster cannot be stopped. Veritas suggests that you bring down the Veritas Access services, enable or disable I/O fencing, and then resume Veritas Access services.
To check the status of I/O fencing
- Check the status of I/O fencing while I/O fencing is not enabled.
Storage> fencing status
To enable majority-based fencing
- Enable majority-based I/O fencing.
Storage> fencing on majority
- Check the status of I/O fencing after enabling I/O fencing.
Storage> fencing status
To disable majority-based I/O fencing
- Disable majority-based I/O fencing.
