Hello everyone, I am new to RancherOS and currently trying to deploy a RancherOS instance with RAID 6 configuration. I setup, configure, and run mkfs.ext4 on the software RAID array before I ran “ros install -c cloud-config.yml” file. After the install completed successfully and rebooted, I was able to see the /dev/md0 in the output of “blkid”. When I rebooted the nodes, however, /dev/md0 disappeared and I need to run “mdadm --assemble --scan” to bring up the software RAID again. May I know what I am missing here? For your reference, I have attached my cloud-config.yml below: #cloud-config hostname: valkyrie-201905071020 rancher: network: dns: nameservers: - 192.168.9.241 interfaces: eth0: address: 192.168.9.20/24 gateway: 192.168.9.1 state: autoformat: - /dev/sda dev: /dev/sda1 fstype: auto runcmd: - wget [http://192.168.9.100/clo/cloud-config.yml](http://192.168.9.100/clo/cloud-config.yml) -P /home/rancher - echo “hello” \>\> /home/rancher/test.org - sudo mdadm --assemble --scan mounts: - ["/dev/md0", “/mnt/raid6”, “ext4”, “”] Thank you, Chris ---

I encountered same problem here. How’s the way to bind the raid volume during reboot?
