| Field | Type | Description | Value(s) |
|---|---|---|---|
name | string | Array name, stamped into the md metadata. Must be 1-32 chars: ASCII letters, digits, hyphens, underscores. Exposed as /dev/disk/by-id/md-name-<name>. | |
level | MDLevel | RAID level. | raid1 |
metadata | MDMetadata | MD on-disk metadata format. Defaults to 1.0, which stores the superblock at the end of the member device so the array can back a bootable partition. Use 1.2 for data arrays that do not need to be bootable. | 1.01.2 |
provisioning | RAIDProvisioningSpec | The provisioning describes how the RAID arrays are provisioned. |

volumeSelector | RAIDVolumeSelector | The volume selector describes how the members of RAID arrays are selected. |
volumeSelector
RAIDVolumeSelector matches member disks with CEL.| Field | Type | Description | Value(s) |
|---|---|---|---|
match | Expression | CEL expression matching the member volumes of the array. Evaluated against each discovered volume with the volume variable;the disk variable is bound for whole disks (empty for partitions), soboth whole disks and partitions can be selected. The system disk and its partitions are never eligible. A volume declared in the machine config also matches on volume_id,the volume name prefixed by its kind ( u- user, r- raw, s- swap),as in volume_id == "r-mirror0". A device Talos does not manage as avolume has an empty volume_id.An encrypted volume matches the same way. Talos builds the array on the opened device, never on the ciphertext, and matches the volume only after the volume manager has prepared it. |
