Subject: [PATCH] multipathd: monitor new multipath dev even if we can't update
|
|
it
|
|
|
|
If a multipath device was created by the multipath command, multipathd
|
|
might not agree with how the device was created. ev_add_map() can reload
|
|
the device with a different table by calling add_map_without_path() ->
|
|
update_map(). If this reloading of the map failed, multipathd was simply
|
|
ignoring the multipath device, even though it still existed.
|
|
|
|
One way that reloading can fail is if a path that multipathd already has
|
|
initialized goes offline. If a multipath device is created by the
|
|
multipath command while the path is offline, it will not use the offline
|
|
path, since multipath won't be able to get the necessary pathinfo.
|
|
However, multipathd will already have the pathinfo for the path, and may
|
|
not even know that it's offline, since the path is an orphan. When it
|
|
tries to reload the device, it will include the offline path, and the
|
|
reload will fail.
|
|
|
|
Instead of ignoring the device if it can't reload it, multipathd should
|
|
just montior it as it is. When the path device is no longer offline, it
|
|
can be added back to the multipath device by calling
|
|
"multipathd reconfigure" or "multipathd add path <path>".
