Mount as user at startup using fstab

[clintcan]

Hi,

In the documentation, it is written (for fstab):
my-bucket /mount/point gcsfuse rw,noauto,user

I tried removing noauto to make it mount at start. This doesn't work. How can I edit fstab in such a way that it mounts the bucket with a specified user id?

You can probably set the allow_other fuse option and appropriately set the --uid and --gid flags to gcsfuse. I would need more detail than "this doesn't work" to know for sure though.

Still: let me urge you to not do this. Requests to GCS are not nearly as reliable as local disk, and you're likely to find yourself with a system that hangs on boot if anything goes wrong.

Hi jacobsa,

What I meant was placing in fstab the following (assuming I do not allow on boot):

my-bucket /mount/point gcsfuse rw,uid=www-data,gid=www-data,allow_other,noauto

When I do the mount /mount/point command, it fails with an exit code of 1.

I can do the alternative gcsfuse -o allow_other --uid=n --gid=n my-bucket /mount/point with no problems, but I prefer placing it in fstab so that I can just call mount directly.

I see, thanks. uid and gid aren't supported in fstab currently. But I'm not sure why you need them. Can you do this

my-bucket /mount/point gcsfuse rw,noauto,user

and then just run the mount command as www-data?

Ok, the original purpose was to let a user for example root mount the /mount/point with a specific user assigned to that directory. Anyways, that works for the meantime. Thanks!

[jacobsa]

Sounds good. Keep in mind that you can do this as root using sudo -u some_user.

Sorry to re-open the discussion about this. But the above comments doesn't answer the question, i.e. mount the bucket when system boot up automatically. Absolutely we can create a init script which call sudo -u some_user -c 'mount /mnt/mountpoint', but is that the only way? I still prefer a single line in /etc/fstab which can mount the gcs bucket as a specified user, e.g. www-data

Hi, Here I have the same issue, someone can help us?

Yes, unless your system supports specifying which user owns the mount helper process in /etc/fstab, you will need to write a script that uses sudo to accomplish this.

Finally I got it with one line in fstab,

bucket-name /foldername gcsfuse rw,allow_other,uid=33,gid=33,file_mode=0777,dir_mode=0777,key_file=/*******.json

But the performance is.. poor at least, is it normal?

Thank you jacobsa
