SYNOPSIS

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

DESCRIPTION

15       fence_tool is a program used to join or leave the default fence domain.
16       Specifically, it starts the fence daemon (fenced) to  join  the  domain
17       and  kills  fenced  to  leave  the  domain.   Fenced can be started and
18       stopped directly without using this program, but fence_tool takes  some
19       added steps that are often helpful.
20
21       Before  joining  or  leaving the fence domain, fence_tool waits for the
22       cluster be in a quorate state.  The user can  cancel  fence_tool  while
23       it's  waiting  for  quorum.   It's generally nicer to block waiting for
24       quorum here than to have the fence daemon itself  waiting  to  join  or
25       leave the domain while the cluster is inquorate.
26
27       Since  fence_tool  join is the usual way of starting fenced, the fenced
28       options -j, -f, and -c can also be passed to  fence_tool  which  passes
29       them on to fenced.
30
31       A  node must not leave the fence domain (fenced must not be terminated)
32       while CLVM or GFS are in use.

OPTIONS

36       -w     Wait until the join  is  completed.   "fence_tool  join  -w"  is
37              equivalent to "fence_tool join; fence_tool wait"
38
39       -h     Help.  Print out the usage syntax.
40
41       -V     Print version information.
42
43       -j secs
44              Post-join fencing delay (passed to fenced)
45
46       -f secs
47              Post-fail fencing delay (passed to fenced)
48
49       -c     All nodes are in a clean state to start (passed to fenced)
50
