Re: Converting RAID5 to RAID6 and other shape changing in md/raid

christian: You can stack the MD levels... So make the 6 500G disks into two 3-disk RAID-0s. Then you have 3 1.5T sized devices (the two RAID-0s and the 1.5T partition) and can build your final RAID-5 on top of that.

Ugly but doable.
