Google Drive external storage broke my owncloud

[stanelie]

Expected behaviour

Attach a google drive external storage and be able to use it

Actual behaviour

It doesn't work well with big files because it is unable to stream (see issue #5949). So I tried to remove the google drive external storage. Now, I get
"Error while loading the list of folders from the server" from the Mac or PC client and I am unable to sync anything. Also, I now get "Your web server is not yet set up properly to allow file synchronization because the WebDAV interface seems to be broken." in the admin panel.

Steps to reproduce

1. Attach external Google Drive storage containing big files
2. weep

Any thoughts on how I can clean up this mess so that I can use ownCloud again without reinstalling from scratch?

[LukasReschke]

@stanelie You could try to disable files_external. Is deleting the mountpoint not possible?

[stanelie]

I could, but I'd rather not.
I was reckless and I messed with the googledrive external storage on a production server. The users are using the external storage app and I'm afraid disabling and re-enabling it will trigger a re-download on their sync clients.
Also, I am the only user affected, so, I'd rather take the long way and fix the underlying issue. Also, we might learn something from this.

[stanelie]

Well,

I upgraded to ownCloud 9 and I was able to see the phantom google drive external storage mount under the admin account and remove it. I can now sync with the client and list available folders.

Maybe there should be a warning when one tries to set up a google drive external storage mount point that it might break everything.

GDrive is now able to stream download since OC 9.0.1 and error handling of unavailable storages have been improved.

Feel free to reopen if you're still getting breakages.
