the "-m 1" is for things like mke2fs(fs formatting) not for
cfdisk(low level partitions)

in order for you to be able to add a new disk to expand/grow
your hardware raid, 3 things must work
- your hw raid controller tools needs to support
dynamically growing the raid array
- your partition tools must be able to grow partition
across multiple disls
( some partition tools allow you to dynamically resize
( partitions on the same disk, 256MB root fs to 512MB
- your filesystem must be able to grow across disks
i'd expect all 3 requirement for adding a 5th disk to an existing
4-disk radi5 setup to fail
- you can make a new raid array of 4 more disks ...
- you can replace a dead disk with a fresh new one
- i doubt you can grow an existing array
- but its late .. maybe i'm missing something
