it's pretty simple
* if you lose the wrong disks all is gone
* if you lsoe the right disks no problem
RAID10 with 4 disk is prcatically a stripe over the data which is
mirrored, wehn you lose two disks containg both mirrors of one of the
stripes your data are done
pretty easy to test - pull out two disks and move them to another
machine, if you take the right ones you have on both a degraded RAID,
can add two blank disks and resync it
that's how i clone machines for years
