# This file causes block devices with Linux RAID (mdadm) signatures to
# automatically cause mdadm to be run.
# See udev(8) for syntax

# raid devices manually

# We process add events on block devices (since they are ready as soon as
# they are added to the system), but we must process change events as well
# on any dm devices (like LUKS partitions or LVM logical volumes) and on
# md devices because both of these first get added, then get brought live
# and trigger a change event. The reason we don't process change events
# on bare hard disks is because if you stop all arrays on a disk, then
# run fdisk on the disk to change the partitions, when fdisk exits it
# triggers a change event, and we want to wait until all the fdisks on
# all member disks are done before we do anything. Unfortunately, we have
# no way of knowing that, so we just have to let those arrays be brought
# up manually after fdisk has been run on all of the disks.
# First, process all add events (md and dm devices will not really do
# anything here, just regular disks, and this also won't get any imsm
# array members either)
