mdadm

This tool activates the healthy software RAID (mdraid). It's important to note that Talos doesn't handle software RAID maintenance. You'll need to create and manage it yourself.

Installation

See Installing Extensions.

Usage

Create soft raid1

# mdadm --create --verbose /dev/md0 --metadata=0.90 --level=1 --raid-devices=2 /dev/sdb /dev/sdc
# mdadm --detail --scan
ARRAY /dev/md/0 metadata=0.90 UUID=86345734:5d4de8db:5a848257:e2917ea5

Mount raid1 to the folder /var/data. Talos will create the partition and format it.

machine:
    disks:
        - device: /dev/disk/by-id/md-uuid-86345734:5d4de8db:5a848257:e2917ea5
          partitions:
            - mountpoint: /var/data

Result will be like:

# talosctl --nodes $NODE mounts | grep '/dev/md'
192.168.1.1   /dev/md0p1                 10.67      0.11       10.56           1.01%          /var/data
