Hello everyone,
for some strange reason I dont't succeed any longer in starting my raid5.
See log below at line
mdadm -Af /dev/md2 /dev/md1 /dev/sdc4 /dev/sdd4
BTW, there is no /etc/mdadm.conf.
Kernels tried are 3.11.6 an 3.12.0
mdadm version is "v3.3 - 3rd September 2013".
Does anyone see what I am missing?
Cheers,
Arnold
