Maintaining GFS for VTS | 221
If VTS server fails to fence
Fencing is a term used to describe when a server is excluded from the GFS cluster. When a server is
not available for updates and cannot vote in the GFS process, it may be fenced off from access to the
file system. You must rejoin that server to the cluster. To verify if fencing is occurring, complete
these steps:
1. Check the /var/log/messages file on the primary VTS server. You may see this message: “VTS
unauthorized to join cluster. Fence failed.”
2. Restart the GFS cluster by bringing GFS down and back up. See "Powering hardware and
starting a cluster" on page 206.
