The upgrade of Aria Operations fails with Error: upgrade.pak.file_copy_failed as shown under the "Software Update" for the status of the upgrade.
Aria Operations 8.x
This issue is commonly caused due to one or more of the Aria Operations nodes running out of disk space during the upgrade.
To verify if the upgrade failed due to a node running out of disk space, carry out the following steps:
Once all nodes have sufficient free disk space the upgrade can be restarted.
We recommend to revert to the snapshot taken prior to the upgrade failure, then implement the procedures to clear or add additional disk space to each Aria Operations node and then starting the upgrade.
