    This topic describes the issue that no data exists in the original data disk directory during instance startup after you migrate a Linux server by using Server Migration Center (SMC). This topic also describes the causes of and solutions to this issue.

    Problem description

    No data exists in the original data disk directory during instance startup after you migrate a Linux server.

    Cause

    By default, the data disks are not attached during instance startup after you migrate a Linux server that are configured with data disks.

    Solution

    After you start your Elastic Compute Service (ECS) instance, run the ls /dev/vd* command to view the data disks. Attach the data disks based on your business requirements. Edit the configuration file in the /etc/fstab directory to allow the data disks to be automatically attached during instance startup.
