Hello!

I was trying to chmod the folders inside the mount point but it doesn't work.

My goals are:

/mnt/mys3bucket/ should have 755 permissions (for chroot)
parent_folder and child_folder should both have 775 permissions

Is this possible to achieve?

Mount Command:

s3fs mys3bucket /mnt/mys3bucket -o use_cache=/tmp -o allow_other -o umask=022 -o iam_role=S3FullAccess -o endpoint=us-east-1

/etc/fstab

s3fs#mys3bucket /mnt/mys3bucket fuse _netdev,use_cache=/tmp,allow_other,umask=022,iam_role=S3FullAccess,endpoint=us-east-1 0 0

Tests:

[root@ec2 ~]# mkdir -pv /mnt/mys3bucket/parent_folder/child_folder
mkdir: created directory ‘/mnt/mys3bucket/parent_folder’
mkdir: created directory ‘/mnt/mys3bucket/parent_folder/child_folder’
[root@ec2 ~]#

[root@ec2 ~]# chmod -Rc 775 /mnt/mys3bucket/parent_folder
mode of ‘/mnt/mys3bucket/parent_folder’ changed from 0755 (rwxr-xr-x) to 0775 (rwxrwxr-x)
mode of ‘/mnt/mys3bucket/parent_folder/child_folder’ changed from 0755 (rwxr-xr-x) to 0775 (rwxrwxr-x)
[root@ec2 ~]#

[root@ec2 ~]# ls -ld /mnt/mys3bucket/ /mnt/mys3bucket/parent_folder /mnt/mys3bucket/parent_folder/child_folder
drwxr-xr-x 1 root root 0 Jan  1  1970 /mnt/mys3bucket/
drwxr-xr-x 1 root root 0 Aug  7 07:48 /mnt/mys3bucket/parent_folder
drwxr-xr-x 1 root root 0 Aug  7 07:48 /mnt/mys3bucket/parent_folder/child_folder
[root@ec2 ~]#

Thank you!

Hi, @ju4npabl0
You run s3fs with umask=022 option, it means umask 022 for all files/directories.
Thus you could not work chmod 0775 to files, if you need to access as 0775 files, you should change umask option value.
Regards,

@ju4npabl0 are you sure you meant -o umask=022 and not -o mp_umask=022 ?
If it's not a typo, that could be your problem?
