Use stripping to join 2 raid1 disks together.
raid1 size is 39000000 sectors
raid2 size is 29000000 sectors
I followed the man page on raidframe as follows:
raidctl -C /root/raid3.conf raid3
raid3.conf:
START array
1 2 0
START disks
/dev/raid0a
/dev/raid1a
START layout
128 1 1 0
START queue
fifo
The resultant combined size is 58753024 sectors. The overhead is about =
5G. The combined size should be around 68000000 sectors. Is it right?
Or my configure is wrong?
