Subject: [PATCH] 90multipath: add shutdown script
|
||
|
|
|
||
|
|
As the device-mapper module is removing all device-mapper tables
|
||
|
|
during shutdown we need to make sure to disable queuing on the
|
||
|
|
multipath devices; otherwise there might still be I/O pending
|
||
|
|
and the removal will fail.
