DR job fails due to low disk space on the drive

This article applies to:

  • Product edition: Phoenix 

Problem description

The disaster recovery (DR) job fails with an AWS_DR24 error.

Cause

The free disk space on the root drive has reduced to less than 250 MB.

Traceback

[2018-10-17 02:19:01,797] [INFO] CloudDRAgent: Import image task id [import-ami-0ff89ecd8ae9517b1], status [deleting] message [ClientError: Unsupported: Not enough free disk space to proceed with import. There must be at least 250MB free.]

SyncError: VM is not valid to create AMI (#100080018)

Resolution

Perform housekeeping of the disk or add more disk space to the drive. 

Verification

Trigger a VM backup first and then trigger the AMI update to get a successful DR job.

Amazon also recommends that the virtual hard disk must contain at least 250 MB of free space. The reason for this is that Amazon injects drivers and possibly other software into the virtual hard disks, so the virtual hard disks need to have enough free space to accommodate these components.
