The issue you are facing:
I use minio S3 storage hosted locally. I needed to move to a new version of minio, which required a whole new server and manual data migration. I’ve replicated credentials etc on the new server, that does not appear to be the issue.
With Nextcloud shut down, I migrated the objects from the old Minio instance to the new one using rclone. This appeared to complete successfully. However when I point the Nextcloud instance at the new server and start it up, I log in and then immediately get the ‘Internal Server Error’ plain-text error page.
Looking at the logs, I see it’s trying to access an object that does not exist on the old or new Minio instance. Toward the end of the logs below, you’ll see the reference to
urn:oid:149645
I’ve tried pointing it back at the old minio, same result - Internal Server Error - with logs trying to access the same non-existent object.
Pretty frustrating - I’ve got all my data, but no way to access or export it.
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- Not sure this is replicable outside my install.
