Managing a Host (Node)

Updated at: Aug 17, 2021 GMT+08:00


To check an abnormal or faulty host (node), you need to stop all host roles on MRS. To recover host services after the host fault is rectified, restart all roles.


You have synchronized IAM users (on the Dashboard tab page, click Click to synchronize on the right side of IAM User Sync to synchronize IAM users).

Figure 1 Synchronizing IAM users (using MRS 1.9.2 as an example)


  1. On the MRS details page, click Nodes.
  2. Unfold the node group information and select the check box of the target node.
  3. Choose Node Operation > Start All Roles or Stop All Roles to perform the required operation.
