Two unsuccessful attempts using the

sudo -u www-data php /var/www/nextcloud/occ files:scan --all

command via Terminal left external storage mounts only quasi-catalogued and, as a result, their contents unbrowsable. (Directories were missing even after successive browser refreshes and cache cleaning.)

Removing the mounts and adding them again — sans the above forced scan — seems to be working. Nextcloud is slowly-but-surely cataloguing. Total drive sizes are inaccurate as it progressively scans volumes one at a time. Those waiting to be scanned are reported inaccurately as size = 0. But all volumes, folders, and files mid-scan now seem browseable and accessible, unlike the inaccessible and unbrowseable condition the fatal files:scan --all error left them in previously.

Is this Issue still valid in NC21.0.3? If not, please close this issue. Thanks! :)
