The question is completely theoretical, and I don’t want to get a ready how-to, and it’s unlikely to be done. So, we have:

  1. 5 HDD x 1Tb
  2. ISO FreeBSD
  3. ISO Debian (or install Debian over the network, then. I don’t know yet if this is realistic)

It is necessary to obtain:

  1. 2 Operating Systems
  2. RAID 5
  3. The ability to exchange data between partitions, and access from FreeBSD to Debian, and vice versa.

What we will definitely not use:

  1. MBR

So, it turns out we will have GPT.

Each OS should occupy 100 GB.

And here are a few questions:

  1. Is it possible to use 2 systems with data interchangeability in RAID 5?
  2. How to do everything with slices and not make a fierce n?
  3. From 100 GB for Debian - 10 we give under the system, 90 are doing in ZFS after installation. Will there be any problems?
  4. For BSD, the ZFS file system. Question just in case: (I am noob in such matters) is there anything unusual waiting for me?

Security Question:

  1. If I install RAID 5 with ZFS when installing BSD, how then will I install Debian ?! Or will the slices help to do everything correctly and beautifully?

Sorry if the question is too general, perhaps stupid, and fundamentally incorrectly posed, but as I said, in these cases I am a complete noob, and asked a question solely to understand the subtleties.

  • On the one hand, the question is too general, on the other hand, it solves one problem. - LFC
  • @LFC, what's the problem? - 0-Level UNIX Monk
  • Ok, no problem, problem, what's the difference - LFC
  • @LFC, what problem are we talking about? - 0-Level UNIX Monk
  • 2 linux-core OS, RAID5, two-way data exchange ???? Or the question is not about that? - LFC
