Do acl permissions work on mergerfs?

[ghost]

I'm trying to merge the drives of two computers but I'm getting errors due to wrong permissions on one of them.

user@A ❯ cat /etc/fstab

I did this in both computers

1. Change the permissions

❯ sudo chown $USER:$USER /mnt/storage
❯ chmod -R ugo+rw /mnt/storage

2. Set the setgid bit, so that files/folder under will be created with the same group as

❯ chmod g+s /mnt/storage

3. Set the default ACLs for the group and other

# Gives read,write,exec permissions for currently existing files and
# folders, recursively.
❯ setfacl -R -m u::rwx,g::rwx,o::rwx /mnt/storage

# Gives rwx permissions by default, recursively.
❯ setfacl -R -d -m u::rwx,g::rwx,o::rwx /mnt/storage

New files are still created without the proper permissions.

What else can I do to make sure all new files are created with 777 permissions?

acl permissions are enabled by default with ext4 drives, but maybe this is not the case for mergerfs. Should I add the acl option to the mergerfs lines in /etc/fstab?

getfacl gives the following for the parent folder of where I've created a file that doesn't have the proper permissions

# file: tmp
# owner: user
# group: user
user::rwx
group::rwx
other::rwx
default:user::rwx
default:group::rwx
default:other::rwx

I just saw that I need the option posix_acl=true for mergerfs.
