-p, --print-nodes |
224 |
Prints the before and after node status, in a format designed to |
|
225 |
allow the user to understand the node's most important parameters. |

It is possible to customise the listed information by passing a |
|
228 |
comma-separated list of field names to this option (the field list |
|
229 |
is currently undocumented), or to extend the default field list by |
|
230 |
prefixing the additional field list with a plus sign. By default, |
|
231 |
the node list will contain the following information: |
|
232 |
|
|
233 |
F |
|
234 |
a character denoting the status of the node, with '-' meaning an |
|
235 |
offline node, '*' meaning N+1 failure and blank meaning a good |
