Subject: [PATCH 79/83] mdadm/udev: Don't handle change event on raw devices
|
|
|
01ff50 |
|
|
|
01ff50 |
The raw devices are ready when add event happpens and the raid
|
|
|
01ff50 |
can be assembled. So there is no need to handle change events.
|
|
|
01ff50 |
And it can cause some inconvenient problems.
|
|
|
01ff50 |
|
|
|
01ff50 |
For example, the OS is installed on md0(/root) and md1(/home).
|
|
|
01ff50 |
md0 and md1 are created on partitions. When it wants to re-install
|
|
|
01ff50 |
OS, anaconda can't clear the storage configure. It deletes one
|
|
|
01ff50 |
partition and does some jobs. The change event happens. Now
|
|
|
01ff50 |
the raid device is assembled again. It can't delete the other
|
|
|
01ff50 |
partitions.
|
|
|
01ff50 |
|
|
|
01ff50 |
So in this patch, we don't handle change event on raw devices
|
|
|
01ff50 |
anymore.
