Because in many cases it destroys your data. I recommend: 1) Show/look at the output of "cat /proc/mdstat" 2) If your arrays shows up there as partially assembled, use mdadm --stop to release the drives. 3) retry "mdadm --assemble --force --verbose /dev/md2 /dev/sd[ijklm]1" 4) If that fails, show the output, then 5) mdadm --stop again, then retry the assemble leaving out the "m", like so: mdadm --assemble --force --verbose /dev/md2 /dev/sd[ijkl]1 And report its output.
