After updating to latest upstream, bug2163711 can be fixed. We don't use rhel only udev rule anymore and we use the udev rules from upstream. So we don't need to modify our rhel only udev rule again. Resolves: bz#2163711 Signed-off-by: Xiao Ni <xni@redhat.com>

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