Expand the capacity of a local data disk

When the size of your data disk is insufficient, you can increase the size of the data disk. When you use an EBS volume or a local data disk as the data disk, you can change the size of the data disk no matter whether the KEC instance is online or offline. This topic describes how to expand the capacity of a local data disk for Linux and Windows KEC instances. For more information about how to expand the capacity of an EBS volume, see Overview.

Precautions

• To protect important data, we recommend that you create a snapshot to back up disk data before the expansion. For more information, see Create snapshots.
• After the capacity of a local data disk is expanded, you must restart the KEC instance and expand its file system. For more information, see Resize the partitions and file system (Linux) or Resize the partitions and file system (Windows).
