Environment: Alfresco Community 5.1f on CentOS7 with Postgres9.6
Phenomenon: Lost some month directory with all files from /alf_data/contentstore/yyyy/
Operation: We removed access authority from one group and moved document folders to other group from share GUI and admin user.
It worked at this point, but we found all folders moved could not access at the next day.
Also found /alf_data/contentstore/yyyy/mm directory was removed.
It is the first time to this kind of problem we encountered.
If you have similar problem, any suggestions or ideas would be appreciated.
