Error S10: Disk partition data sync fails

Symptoms

An SMC migration job fails with the error "S10_*: Data synchronization test for disk partition files fails". Possible error codes include:

• S10_R255

• S10_R1

After you resolve the network issue, run the SMC client to retry the operation. For more information, see Run the SMC client.

Causes

This error occurs when the SMC client on the source server runs a file-level data synchronization test for a disk partition. Possible causes:

• S10_R255: The source server cannot access the destination instance over TCP port 8703.

• S10_R1: The rsync version on the source server is not supported.

Solutions

Apply the solution that matches your error code.

• S10_R255

  Check if the destination instance is reachable from the source server on port 8703.

  1. Verify that the destination instance's security group allows inbound traffic on port 8703 with no conflicting rules.

     Note

     By default, SMC automatically associates a temporary security group with the destination instance to allow inbound traffic on port 8703.

  2. Run telnet to test connectivity to port 8703 on the destination instance. If the connection fails, check your local network and intermediate devices (firewalls, proxies) for outbound IP or port restrictions.

  3. Check whether Cloud Firewall is blocking the connection by reviewing access control policies for the internet firewall and VPC firewall. Firewall settings.

• S10_R1

  Run rsync --version on the source server to check the installed version.

  Rsync must be version 3.0.6 or later and must support ACL. If 'ACLs' is not listed in the Capabilities output, reinstall rsync and retry the job.
