Steps to reproduce

  1. Setup SMB share on Machine NAS
  2. Setup External Storage /mysmb inside nextcloud as user ME on Machine SERVER
  3. Share subdirectory /mysmb/public as user ME to user FRIEND
  4. Logout user ME and FRIEND from nextcloud
  5. Shutdown Machine NAS
  6. Login as user FRIEND (but not user ME before)

Expected behaviour

User FRIEND should see all his files. The share should be an empty directory and an error message should be shown, if opened.

Actual behaviour

User FRIEND does not see any of his files, but an overall error message is shown: This directory is unavailable, please check the logs or contact the administrator

Workaround

Login as aser ME and refresh the files view before last step. Nextcloud somehow recognized, that the SMB share is offline. In this case, user FRIEND is able to see his files, but there is no (not even empty) directory for the missing share in the regular files view. There is just an entry inside the shareoverview, which leads to the error message operation is not allowed, if clicked.

This exception trace is copied from the nextcloud page /nextcloud/settings/admin/logging and repeats every 10-60 seconds. This might be the case, because user FRIEND has setup a nextcloud desktop client, which tries to reconnect periodically (nextcloud unavailable as mentioned above)

I did some additional testing:

If the SMB service (i.e. smbd.service) on machine NAS is just shutdown, but the machine is reachable, the error message is not shown. User FRIEND is able to see his files, but there is no empty directory for the offline share. The share is still visible inside the shareoverview.
If the SMB share is back online, User FRIEND is not able to see the share again until User ME signs into his nextcloud account.

Is this Issue still valid in NC21.0.2? If not, please close this issue. Thanks! :)

Fixed. Now user ME sees all files and no initial error message. If the share is accessed, there is an popup "Storage is temporarily not available".
