• This error may appear in the VAMI update page: There is not enough space on the disk(s)

Environment

• VMware vCenter Server 7
• VMware vCenter Server 8

Cause

• A failure in the upgrade script occurs when attempting to modify permissions on /storage/archive/vpostgres. If the directory does not exist, the chown command fails, preventing the upgrade from progressing or rolling back correctly via the VAMI.

Resolution

• Revert vCenter:
  • Restore the vCenter Server Appliance (VCSA) to the snapshot taken prior to the patch attempt.
• Create the Directory:
  • Access the vCenter via SSH, login as root, and run the following command to create the missing directory: mkdir /storage/archive/vpostgres
• Re-attempt update from VAMI:
  • Since the folder object exists, it can now run chown on the above folder to create the permissions as needed to complete the update.

Additional Information

If the folder exists, but the issue persists. Raise a case with Broadcom Support.
