Boot OS from Storage Spaces Array?

[evolucian911]

I kept my Stripped array (4 nvme in hyper m.2) plugged into a workstation that I was about to install a fresh server 2025 OS onto a new Nvme drive (that makes 5 nvme total in that system).

My storage spaces array was listed and there was no error or anything indicating that I cannot install the OS.

I didn't end up trying as it's mainly used as storage for storage I wouldn't mind losing ( scratch disk, gpu pass through VMs, some games).

Anybody can confirm that it's possible to boot from it? I havnt seen any new documentation or info on the matter.

I'm thinking of backing up the data temporarily and trying it out at some point. But is this confirmed working?

Storage Spaces is a method to pool disks of any type or size.You need a running Windows to organize Spaces with configurable data location, redundancy or tiering so you cannot boot from.

I read last year that microsoft plans to add boot support for refs volumes, but it didn't mention storage spaces as the underlying storage.
Personally I would not trust it (yet)

go for it and then post the results

ReFS is like ZFS a modern filesystem with checksums/bitrot protection and Copy on Write that avoids a corrupt raid or filesystem on a crash during write. CoW can give you snaps of the former datastates (not in current ReFS). On ZFS you can use such snaps even as bootenvironments to boot former OS states so ReFS booting has many future options.

I really hope Microsoft goes ahead with ReFS as it is a huge improvement over ntfs (adopting ZFS would be far better, OpenZFS on Windows is nearly ready and superiour to ReFS in nearly every aspect).

Booting from a disk mirror (hardware raid, fake raid on windows or software raid) can make sense for availability. Storage Spaces does not offer raid over disks so beside the fact it does not work, it would make no sense it it would.
