New issue 724 by [email protected]: improve man page documentation of gnt-node failover
http://code.google.com/p/ganeti/issues/detail?id=724

What software version are you running? Please provide the output of "gnt-
cluster --version", "gnt-cluster version", and "hspace --version".

root@vserver8:~# gnt-cluster version
Software version: 2.9.4
Internode protocol: 2090000
Configuration format: 2090000
OS api version: 20
Export interface: 0
VCS version: v2.9.4
root@vserver8:~# gnt-cluster --version
gnt-cluster (ganeti v2.9.4) 2.9.4


What distribution are you using?

Ubuntu 12.04.4 LTS


The manpage of gnt-node does not mention that a failover will stop instances:

   FAILOVER
       failover [-f] [--ignore-consistency] {node}

This command will fail over all instances having the given node as primary to their secondary nodes. This works only for instances having a drbd disk template.

Normally the failover will check the consistency of the disks before failing over the instance. If you are trying to migrate instances off a dead node, this will fail. Use the --ignore-consistency option for this purpose.

       Example:

              # gnt-node failover node1.example.com



Command line help of gnt-node is ok IMHO:

failover - Stops the primary instances on a node and start them on their secondary node (only for instances with drbd disk
                      template)


thanks
