- can I really assume that RAID 5 on 2 hdds (degraded mode) will
function as raid 5?
You should test by using loopback devices and files. But why degraded?
raid5 of two disks should look like raid1.
I meant to ask whether raid 5 on 2 disks will function as raid1 :(
A 2-disk raid5 and a 2-disk raid1 put the data in exactly the same
place - is that what you wanted to know?
Is the same valid for RAID-10?
Let's say, you degraded a 4-disk RAID-10 to just 2 (proper) disks.
Then, you want to migrate it to 2-disk, 3, 4, and eventually, 5-disk
RAID-5 array.
Would the RAID-10 -> RAID-5 migration be as easy as in RAID-1 -> RAID-5
case?
