Why Is the EVS Disk Size Not Updated in the BMS OS After the EVS Disk Capacity Has Been Expanded?


If this occurs, scan block devices in the BMS OS. For example, for the sdh disk of Red Hat, run the echo 1 > /sys/block/sdh/device/rescan command.

Can I Use a VBS Backup to Restore an EVS Disk Whose Capacity Has Been Expanded?

Yes. If you back up an EVS disk using VBS and later expand the capacity of the EVS disk, you can still use the VBS backup to restore the EVS disk. However, the capacity of the restored EVS disk reverts to the original value due to file system restrictions. To avoid this, create a VBS backup for the EVS disk after expanding its capacity.

What Are the Restrictions for Attaching an EVS Disk to an ECS?
  • The EVS disk and the target ECS must be located in the same AZ.
  • The EVS disk must be in Available state.
  • The target ECS must be in Running or Stopped state.
