- Raid Controller: 3Ware 9650SE-24M8
- Disks: 21 x 1TB RAID5
- Stripe 64KB
- OS: Windows Server 2003 SP2 32x
- Disk: Dynamic 19557.44GB
- Volume: Capacity 15832.19GB
I guess my array must have a 4KB block size which is limiting it to 16TB. I think I would have to switch to a 64KB block size to be able to see a maximum of 256TB. Or create another unit on my controller to go above 16TB of storage.
Unfortunately I have already added over 16TB, ideally I would like to shrink the array and reclaim the 5 disks that aren't doing anything. I don't think this is possible. More likely, can I change the block size so 20TB becomes visible in windows?
My problem is the array has accepted over 16TB of disks but isn't displaying it. I can see no way to reclaim the disks without destroying the array or changing the cluster size. I'm concerned changing the cluster size might take days/weeks/months? using Acronis. I've opted to purchase four 3TB drives to migrate the data off and then I'll rebuild the array as two smaller volumes. Thanks for your help :)
