fence_tool(8)

NAME
fence_tool - A program to join and leave the fence domain

SYNOPSIS
fence_tool <join | leave | wait> [OPTION]...

DESCRIPTION
fence_tool is a program used to join or leave the default fence domain. Specifically, it starts the fence daemon (fenced) to join the domain and kills fenced to leave the domain. Fenced can be started and stopped directly without using this program, but fence_tool takes some added steps that are often helpful. Before joining or leaving the fence domain, fence_tool waits for the cluster be in a quorate state. The user can cancel fence_tool while it's waiting for quorum. It's generally nicer to block waiting for quorum here than to have the fence daemon itself waiting to join or leave the domain while the cluster is inquorate. Since fence_tool join is the usual way of starting fenced, the fenced options -j, -f, and -c can also be passed to fence_tool which passes them on to fenced. A node must not leave the fence domain (fenced must not be terminated) while CLVM or GFS are in use.

OPTIONS

-w  Wait until the join is completed. "fence_tool join -w" is equivalent to "fence_tool join; fence_tool wait"

-h  Help. Print out the usage syntax.

-V  Print version information.

-D  Enable debugging output and don't fork (also passed to fenced)

-j secs
    Post-join fencing delay (passed to fenced)

-f secs
