Subject: [PATCH] libmultipath: select resize action even if reload is forced
|
|
|
8b67ad |
|
|
|
8b67ad |
The ACT_RESIZE action is the same as the ACT_RELOAD action, except that
|
|
|
8b67ad |
it flushes outstanding IO because the device size is changing and
|
|
|
8b67ad |
the new size might be too small for some of the outstanding IO. If we've
|
|
|
8b67ad |
detected a size change, and a forced reload is requested, we still need
|
|
|
8b67ad |
to flush the IO because the reload will change the device size.
