Windows Server 2022: Is there built-in support for OS drive software RAID1/mirror?

November 6

Hi, in the old days allegedly Windows allowed you to mirror disks containing the OS[1]. Is this supported for Windows Server 2022? When I right click on "Disk 0" the New MIrrored Volume is greyed out. And if I try Convert to Dynamic Disk, it fails with the following error: "There is not enough space available on the disk(s) to complete this operation". I get this error if I have a Disk 0 with all its space used, and also when there are is 11GB unallocated space.

I have also tried creating a partition on the 11GB allocated space whether full or not and then converting to dynamic disk gives me a different error: The selected GPT formatted disk contains a partition which is not of type 'PARTITION_BASIC_DATA_GUID', and is both preceeded and followed by a partition of type 'PARTITION_BASIC_DATA_GUID'.

I have tried disabling the recovery partition with reagentc /disable but still get the same errors.

Any suggestions? Do I need to create and boot a Windows Server recovery ISO or something like that?
