nextcloud.log not found

Hi guys,

I have run into an issue when trying to update my Nextcloud server.
When the updater reached the step “Check for expected files” it lists “nas_data” as an unexpected file.
As can be seen in the config file this is the directory used as “datadirectory”. This choice was made during config because I wanted to use a directory on my nas that is mounted to “path/to/nextcloud/nas_data”.

I looked into changing the name on the mounted directory to “data” and changing the path in the config.php-file, but this looks like a bad alternative for a few reasons. One of them being that each file in the db carries its path including the path to “nas_data”.

Is there another way of resolving this?

Kind regards,

Hi guys!

I’m still stuck on this issue. Anyone have a suggestion on how I can solve this?

Thank you for replying to my post.
Alright, seems like I have to move the data direcotry.
The only real problem I see is the oc_storage part. Does it mean that I have to manipulate the tables in the database?
Regards Leo

Correct. Search for “update oc_storages” and some references should come up if you want some hints.
