Infoblox member upgrade failed [ Edited ]

[#1]

Hi all,

after upgrade tests in LAB. did a revert and new upgrade from 8.5.2 to 8.5.5.
Distribution and Upgrade Test were both successful.
4 of the 5 members completed the upgrade successfully.
One member gives the following message after the reboot:

1 of 1 node has failed upgrade - Upgrading: Syncing storage files...

We did:

* an additional reboot of the member

* reset database on this specific member and added the member back to the Grid

Unfortunately without any success.
