     Hi,
     I would like to request for two features of the Linux RAID subsystem to be
     integrated into webmin.
     1) It would be very nice to be able to assign GLOBAL spares to RAID
     devices. GLOBAL spares are spares which are shared among RAID devices.
     This is now made possible with the 'spare-group'  option in the mdadm.conf
     file. Having disks in the same spare-group shares them among raid devices.
     Very handy in my opinion.

   That's a nice idea, although sadly my test systems don't have enough disks
   at the moment for me to develop this! Patches are welcome though.

     2) It is not possible to add unpartitioned disks as RAID disk inside the
     RAID Module at this moment. You first have to create a partition (Linux
     RAID) on each disk for the module to see them as usable disks. The real
     big  advantage  for  not  having  to use partitions is performance.
     Unpartitioned raid devices perform better then partitioned one because the
     partition breaks the alignment of the disks.

   Cool, I didn't know this was possible - support for it will be in the next
   Webmin release.
