assemble didn't quite (was "Re: all of my drives are spares")

Stopping was easy:

  diskfarm:~ # for A in 51 52 53 54 55 56 ; do mdadm --stop /dev/md$A ;
  done
  mdadm: stopped /dev/md51
  mdadm: stopped /dev/md52
  mdadm: stopped /dev/md53
  mdadm: stopped /dev/md54
  mdadm: stopped /dev/md55
  mdadm: stopped /dev/md56

Restarting wasn't as impressive:

  diskfarm:~ # for A in 51 52 53 54 55 56 ; do mdadm --assemble /dev/md$A /dev/sd[dcblfk]$A ; done
  mdadm: /dev/md51 assembled from 3 drives - not enough to start the array.
  mdadm: /dev/md52 assembled from 3 drives - not enough to start the array.
  mdadm: /dev/md53 assembled from 3 drives - not enough to start the array.
  mdadm: /dev/md54 assembled from 3 drives - not enough to start the array.
  mdadm: /dev/md55 assembled from 3 drives - not enough to start the array.
  mdadm: /dev/md56 assembled from 3 drives - not enough to start the array.

  diskfarm:~ # mdadm --detail /dev/md51
  /dev/md51:

  diskfarm:~ # grep md51 /proc/mdstat
  md51 : inactive sdk51[6](S) sdl51[4](S) sdf51[5](S) sdc51[1](S) sdd51[3](S) sdb51[0](S)

Still all spares.  And here I was hoping this would be easy ...


Thanks again
