Force a file scan in NextCloud

To force a scan after a manual file transfer, for example, can be done as follows:

sudo -u www-data php occ files:scan --all
  files:scan [-p|--path="..."] [-q|--quiet] [-v|vv|vvv --verbose] [--all]
  [user_id1] ... [user_idN]

  user_id               will rescan all files of the given user(s)

  --path                limit rescan to the user/path given
  --all                 will rescan all files of all known users
  --quiet               suppress any output
  --verbose             files and directories being processed are shown
                        additionally during scanning
  --unscanned           scan only previously unscanned files

Doing a large MySQL dump

After discovering that PHPMyAdmin is not suitable to dump or insert large databases, I did a quick search into how things are done by command line.

This worked well and my database was finally not corrupted. Host 1 is a cheap shared hosting provider with a few limitations regarding to internal data transfer, CPU and memory. Host 2 is a VPS with 4 cores, 4GB of memory with an overall decent data speed.

Keep the passwords ready for both hosts.


mysqldump -u [USERNAME] -p [DBNAME] | gzip > [/path_to_file/DBNAME].sql.gz

Copy the file over to Host 2


gzip -d [/path_to_file/DBNAME].sql.gz
[/path_to_mysql/]mysql -u [USERNAME] -p

Be very aware of what you are doing in the next steps since it involves a drop. And when you drop the wrong database, all that’s left is the cold sweat on your forehead.

SOURCE [/path_to_file/DBNAME].sql;

I have no idea why my fuse got bonked, but I simply made a folder named fuse in the dev folder and everything works as intended again.
