Raajeev, Thanks for the feedback.
I'm looking to create a RAID1 (mirror) on the OS drives and 12 RAID 0 volumes of 3TB each on the 12 3TB drives. Our target hardware is 12 Dell 720xd boxes. They are currently configured without the 2 OS drives in use and with the 12 3TB drives configured as 12 2TB RAID0 volumes, with the first 2TB volume standing in for the OS drives. This configuration means that 1/3 of our storage is unavailable because of the limits in the Crowbar RAID/BIOS (not sure which actually causes the limit). Given the OSS status difference between 1.6 and pebbles, do you have any suggestions on which is a better target for this enhancement? Also, I haven't dug too deeply into the source code for Crowbar/Chef so I don't have a good idea of how complex this proposed change might be. Is it simply a issue of re-scripting the hardware discovery for our specific configuration and dictating the correct RAID config or are there deeper complications?
