A RAID-5 set can be expanded by adding extra drives. This requires "restriping" the array which means (almost) every block must be written to a different place. This option allows such restriping to be done while the array is online.
thats also a very risky operation as its extremely difficult to make it restartable in case of a mishap during hte many-hours-long restriping operation. I wouldn't undertake this on any production system without a full backup first.
