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.
It would probably be faster to backup, rebuild and restore too...
Besides saying it is available in the latest kernels is like saying it's available in another OS... That's nice, but does nobody here any good.
