contents of mounted drive not visible in Apache/2.4.18 (ubuntu)

Question

This question was initially posted on Super User. I didn't get any answer there so re-posting here:

Our cluster's apache setup is as such: each user has a directory ~/public_html, and any files (including soft linked files) inside this directory are accessible through http. I have files on another server (serverB) which I mounted to our cluster using the flowing command:

sudo mount -t cifs -o vers=3.0,uid=10069,gid=10069,credentials=secrets //xxx.xxx.edu/path/to/source public_html/serverB

When I ssh into the cluster, I could assess all mounted files just as if they were present on the cluster. I could also see a folder named "serverB" on http. However, serverB appears as an empty folder on http, with none of its contents visible. I was wondering if it's at all possible to make all contents of mounted serverB available through http as well?

I did further research on related topics. This post is describing a very similar issue (unsolved, unfortunately): Cannot see mounted CIFS directory from FTP client

A few other posts mentioned a "allow_other" option, but it seems to be specific to mount --bind or s3fs, unless I'm missing something.

• Mounted with bind folder doesn't appear in FTP client if mounted a folder in a volume

Answer 1

Try to mount your share using the dir_mode and file_mode to something like 0550 (files and folder accessible in read and execute).

sudo mount -t cifs -o vers=3.0,uid=10069,gid=10069,dir_mode=0550,file_mode=0550,credentials=secrets //xxx.xxx.edu/path/to/source public_html/serverB

Best regards.
