# mdadm --stop /dev/md0 # mdadm -A /dev/md0 will result in the array started with 3 drives out of 4 again. what am I doing wrong? Akos
AFAIK, mdadm -A <raid device> will use /etc/mdadm.conf to know what underlying partitions you mean with your /dev/md0. So, try # mdadm --stop /dev/md0 # mdadm -A /dev/md0 /dev/sd[abcd]1 And then have a look on your /etc/mdadm.conf, especially the line starting by ARRAY /dev/md0 ...
