RN31600 and RAID1 with 5 disks
Hello all. I just bought a RN31600 and need to use it with 5 disks in RAID1 mode. However, as long as i put more than 2 disks in, the option only allows to create raid5 or raid6 with my 5 drives. I...
Creating a RAID1 on 5 HDDs is possible from SSH though.
Don't know if I should advise that, it depends on your experience in Linux systems.
I tried it on my unit and it worked:

Hi,
As far as I know, RAID1 on 5 HDDs is not supported on ReadyNAS, even in Flex-RAID.
Maybe log a feature request?
If you're idea is to swap a HDD from time to time, RAID6 would allow you to do just that no? And you would have much bigger volume than a RAID1 (RAID1 on 5 HDDs will give you capacity of one HDD, RAID6 on 5 HDDs will give you capacity of 3 HDDs).
I do think it's not a good idea to do it this way, but RAID6 would do what you need.
