AW: other RAID features

Hi, 

Please,  any body know if there is a plan to support
more RAID features under Linux?  If yes, when.
I am interested in two of them (can either online or offline, 
but online will be really good):
1. Expend capacity.
2. RAID level migration.

Check out the raidreconf tool at http://unthought.net/raidreconf/index.shtml, I've sucessfully used it to add a new disk to a raid5 array (4 Disk ==> 5 Disk), thus extending the capacity without data loss. 

Bye, Martin
