We're building an array of 12x 2TB drives in a RAID60 array using an Adaptec hardware card.
It's taking a long time to build/verify, and performance is slow. We've worked out that it will be around two weeks before the build/verify completes.
I'm currently tossing up whether to drop the whole thing and initialise using the clear method (ie zero out all the disks), but there is already 2TB of data on there so it's no small task.
A big concern is what happens if a disk fails during the build/verify phase - is our data safe? I can't find any documentation on this.
