Subject: [RHEL7.9 PATCH 67/71] udev: Ignore change event for imsm
|
|
|
5bf14f |
|
|
|
5bf14f |
When adding a device to a container mdadm has to close its file
|
|
|
5bf14f |
descriptor before sysfs_add_disk(). This generates change event.
|
|
|
5bf14f |
There is race possibility because metadata is already written and other
|
|
|
5bf14f |
-I process can place drive differently. As a result device can be added
|
|
|
5bf14f |
to two containers simultaneously.
|
|
|
5bf14f |
From IMSM perspective there is no need to react for change event. IMSM
|
|
|
5bf14f |
doesn't support stacked devices.
