"ghost" external storage entries that cannot be listed or removed

[pmhausen]

Hi all,

while analysing performance problem in a larger installation for a not-for-profit org I did an occ files:scan --all and see this error message:

Starting scan for user 146 out of 234 (*******)

#18 {main}

But:

# su -m proserver -c "php occ files_external:list --all"
No mounts configured

How can I find out the issue with that particular account?

Thanks,
Patrick

Hi,

You could temporary increase your loglevel to debug level (loglevel => 0 in config.php), launch your command and watch the nextcloud log file. It may contain exception details, or significant information.

Thanks for the hint, but “nope”.

Even with loglevel => 0 absolutely nothing in the log.

Kind regards,
Patrick

Remote share not found

This exception is generated only if there is one problem with one of the External Storages.

		if ($this->testRemote()) {
			// valid Nextcloud instance means that the public share no longer exists
			// since this is permanent (re-sharing the file will create a new token)
			// we remove the invalid storage
			$this->manager->removeShare($this->mountPoint);
			$this->manager->getMountManager()->removeMount($this->mountPoint);
			throw new StorageInvalidException("Remote share not found", 0, $e);

As it’s writtent in the comment, if you have one storage with a “session token”, you’ll need to reactivate it.

So
→ check if your storages are all still available ?
→ do they need to re-enter login/passwords ?

Yours,
