Table oc_filecache has cache information. But that information is used in oc_share to understand which files are shared with whom. Hence the information in that table is critical. If there is a path issue then use: 

   cd /var/www/html/owncloud/
   sudo -u apache php occ files:scan --all

If the above --all option leads to "Out of memory error" on large deployments we can use: 

#Assuming data directory to be /mnt/files and most files owned by user admin
for A in $(ls /mnt/files/admin/files/); do 
    echo "Going to execute" /usr/bin/sudo -u apache /usr/bin/php -f /var/www/html/owncloud/occ files:scan --path "admin/files/$A"; 
    /usr/bin/sudo -u apache /usr/bin/php -f /var/www/html/owncloud/occ files:scan --path "admin/files/$A"; 
done


For faster recovery we can also given path such as 

   sudo -u apache php occ files:scan --path "admin/files/HR DEP/hr2"

If apache is running with other user privileges eg apache then you may have to do 'sudo -u apache' instead of 'sudo -u daemon'

The above scan also helps with "File does not meet checksum issue" if any reported by owncloud client

In any case do not truncate or delete rows from oc_filecache manually or else all sharing will get broken.

Refer:


For file locks error during scan

We can get file locked error during scanning or also during regular operations via client / Web UI. In such cases go to maintenance mode, delete all rows from filelocks table and then switch of maintenance mode using: 

    cd /var/www/html/owncloud
    sudo -u apache php -f occ maintenance:mode --on

    (With MySQL)   truncate table oc_filelocks;

    cd /var/www/html/owncloud
    sudo -u apache php -f occ maintenance:mode --off
