So I really would do that till you have figured out > if the cable is falky or not. > Adding an internal bitmap to an existing array will not destroy any data, correct? mdadm --stop /dev/md0 mdadm --assemble /dev/md0 /dev/sdc1 /dev/sdd1 mdadm /dev/md0 --re-add /dev/sde1 appears to do the trick (still sync'ing...) Anyway I wonder why the array did not come up automatically as 2 out of the 3 devices were still working and in sync. On previous occasions with just the same kind of setup, this always worked fine out of the box. Thanks for your help!
