+
+ This command changes the role of the node. Each options takes
+ either a literal yes or
+ no, and only one option should be given as
+ yes. The meaning of the roles are described
+ in the manpage
+ ganeti7
+ .
+
+
+
+ In case a node is demoted from the master candidate role, but
+ there are not enough new nodes for this case, the operation
+ will be refused. To override this check, pass the
+ option.
+
+
+
+ Example (setting a node offline, which will demote it from
+ master candidate role if is in that role):
+
+# gnt-node modify --offline=yes node1.example.com
+
+
+
+ Example (setting the node back to online and master candidate):
+
+# gnt-node modify --offline=no --master-candidate=yes node1.example.com

+
+ This commands (tries to) forcefully reboot a node. It is a
+ command that can be used if the node environemnt is broken,
+ such that the admin can no longer login over ssh, but the
+ ganeti node daemon is still working.
+
+
+
+ Note that this command is not guaranteed to work; it depends
+ on the hypervisor how effective is the reboot attempt. For
+ Linux, this command require that the kernel option
+ CONFIG_MAGIC_SYSRQ is enabled.
+
+
+
+ The option can be used to skip
+ confirmation, while the option is
+ needed if the target node is the master node.
