Folders get unshared by mistake/"magic" after storage IO freeze

Nextcloud version: 14.0.6
Operating system and version: centos 7.x
Apache or nginx version: Apache 2.4.6
PHP version: 7.1.26

The issue you are facing:

A user told me, that when she wants to verify the sharing options for a document, sometimes the sharing is removed and she has to reenable it for the document.

This happens from Firefox and Chrome on Mac who she clicks on the little chain symbol.

In her history she also sees, that a link was removed.

Clicking on the three dots -> Details did not delete the sharing.

This happens accordingly to her, after a IO storage freeze / high IO load on our storage Cluster for about an hour.

No other Application/VM or any other user told us about any kind of a problem.

Is this the first time you’ve seen this error? (Y/N):


Steps to replicate it:

  1. click the chain symbol
  2. the link is disabled (unchecked)

The output of your Nextcloud log in Admin > Logging:

no logs from that user … the problem last time occurred days ago.

Currently she is not checking any links as the might get lost…

Thanks for any hints or feedback.

Hi, pity that no one has any ideas or suggestion. The problem still exists after an update to Nextcloud 14.0.8.
