Hi,

I'm currently in the process of converting a 3 disk RAID5 array into a 4 disk 
RAID5 array. I'm using mdadm 3.1.4 and Linux kernel 2.6.35-28-generic 
(Ubuntu). My questions now is this conversion save in a live (running) system? 
Or is this now allowed/supported?

Thanks.

Best regards,
Stefan
