What do you see when issuing:
Any file system in Moodle has to be created manually inside /pathtomoodledata/repository/ or one could use a symlink as I have done to mount points.
In a Moodle 33 that's using a Google Bucket I have a partition called home that is the largest and use it for various versions of Moodle data dirs:
contents of above
lrwxrwxrwx. 1 apache apache 13 Sep 24 09:29 gbucket -> /mnt/gbucket/
lrwxrwxrwx. 1 root apache 7 Oct 2 15:29 google -> /mnt/gb
lrwxrwxrwx. 1 root apache 14 Sep 24 09:43 sosfiles -> /mnt/sosfiles/
lrwxrwxrwx. 1 apache apache 17 May 15 10:31 unirepo -> /var/www/unirepo/
You can see I have one physical ... ie, on the drive of the server ... unirepo
Moodle sees that as 'unirepo'
One to another backend server in that network /mnt/sosfiles/ - sosfiles that's a sshfs
Moodle sees that as 'sosfiles'
And two that are mount points for the Google Bucket ...
the 'alias' for 'google' is really the mount point /mnt/gb/ which was mounted via gcsfuse part of the google SDK linked /info provided previous post.
That's not the same as other fuse's extensions to os.
here's what I had to use to mount one of the buckets .... edited for security reasons:
mount -t gcsfuse -o rw,allow_other,nonempty localname /mnt/themountpointname
Google docs explain options bu that 'localname' is the name given in Google config of the bucket.
I don't add anything to config.php files of the various moodles.
However, whatever you called the mount point example_xxx is what you should see when setting it up in moodle ... the box you type in is really meta data. If you don't see it in the pick list think it means Apache can't see it ... and if apache can't see it, Moodle certainly can't. :\
Not at all sure one could use a Google bucket as the location of Moodledata ... matter of fact ... think that would lead to some issues. Besides, fees for Google are by usage .... not only size but traffic. Even if those look extremely cheap ... shown in pennies ... on any Moodle used on a regular basis, that could rack up a rather large variable bill I think. Can't budget for that!
