Subject: [PATCH] udev-md-raid-assembly.rules: Skip non-ready devices
|
||
|
|
|
||
|
|
If a device isn't fully initialized (e.g if it should be
|
||
|
|
handled by multipathing) it should not be considered for
|
||
|
|
md/RAID auto-assembly. Doing so can cause incorrect results
|
||
|
|
such as causing multipath to fail during startup.
|
||
|
|
|
||
|
|
There is a convention that the udev environment variable
|
||
|
|
SYSTEMD_READY be set to zero for such devices. So change
|
||
|
|
the mdadm rules to ignore devices with SYSTEMD_READY==0.
