Proxmox Inherit existing Raid10 array

[ashb1]

Hi All,
I have a storage system running Windows Server 2019, with a single RAID10 array with about 280TB of storage. It also has a single 1TB SSD for OS.

There's an onboard raid controller that presents the entire array as a single disk to the OS. Windows has it formatted as ReFS.

I want to turn this Windows machine into a Proxmox machine, and adopt it into my existing cluster of 3 other ProxMox hosts.

Is there a way to install Proxmox instead of Windows Server, and then mount the Raid10 array as it exists with all of the data?

Thanks!

Hi,

there is only limited support for ReFS in Linux, the only option that I am aware of is the closed-source driver from Paragon [1]. I don't have any experience with it, so I cannot tell you if it works well.

If you can, I'd suggest reformatting with a Linux-native file system (e.g. ext4, xfs). If you want to use ZFS, you should pass the disks directly and use ZFS's Software RAID features.

Got it, thanks. Will look at finding a temporary storage transfer location so I can reformat the RAID array with Proxmox.
