Epeisis me hotadd bazeis spare diskoys se raid5 array.

  Ayto poy mallon theleis (kai den to exo dokimasei) einai to GROW:

GROW MODE
       The  GROW  mode  is  used  for changing the size or shape of an
       active array.  For this to work, the kernel  must  support  the
       necessary change.  Various types of growth are being added dur-
       ing 2.6 development, including restructuring a raid5  array  to
       have more active devices.

  Koitakse to sxetiko meros sto man toy mdadm.
