Cluster Disk Swap

Step 1: Commit the list of added disks

$ vim format.yaml 

host.
  - server-host4
  - server-host5
  - server-host6 
disk.
  - /dev/sda:/data/chunkserver0:90 # Replace the disk that came up
  - /dev/sdb:/data/chunkserver1:90 # Replaced disk
  - /dev/sdc:/data/chunkserver2:90 # Replacement disk 

⚠️ WARNING:

The format.yaml file should only be filled with the list of disks on the added machines, DO NOT fill it with the list of disks that are already in service on the cluster, to avoid irreparable damage.

Step 2: Pull up the service

$ dingoadm start --id serviceId
