From 3a77acd7170199adc690332ded37c41f067c720e Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Mon, 27 Mar 2017 11:15:44 +1100 Subject: [PATCH] udev-md-raid-assembly.rules: Skip non-ready devices References: bsc#956236 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.
