Subject: [PATCH] IPsrcaddr: Better error message when no matching route found
|
|
|
92e3c0 |
|
|
|
92e3c0 |
If OCF_RESKEY_destination is not explicitly set and `ip route list`
|
|
|
92e3c0 |
can't find a route matching the specifications, the NETWORK variable
|
|
|
92e3c0 |
doesn't get set. This causes a certain failure of the start operation,
|
|
|
92e3c0 |
because there is no PREFIX argument to `ip route replace` (syntax
|
|
|
92e3c0 |
error). It may also cause unexpected behavior for stop operations (but
|
|
|
92e3c0 |
not in all cases). During a monitor, this event can only happen if
|
|
|
92e3c0 |
something has changed outside the cluster's control, and so is cause
|
|
|
92e3c0 |
for warning there.
|
|
|
92e3c0 |
|
|
|
92e3c0 |
Exit OCF_ERR_ARGS for start, log debug for probe, log warning for all
|
|
|
92e3c0 |
other ops.
|
|
|
