From 13298bf138e65f094a9368173c0cfba6c12ce875 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Wed, 2 Dec 2015 13:00:15 +0100 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.
