I want to share the drives of two computers using Manjaro Linux and see them all as one directory in both computers.

I’ve been using mergerfs and sshfs and it was working when I shared one drive of B with A, merged them there and shared the merged folder back with B. Now I’ve tried merging the drives of B too but I haven’t managed to do it.

If possible I would like the computers to still work while the other is disconnected. NFS made one computer hang when the other was disconnected which is why I ended up using sshfs.

The only error I had before was some applications giving input/output error or permission denied. Which I guess it’s because I didn’t have the proper permissions. I would like to avoid that error too, without having to execute something like chmod -R 777 /mnt/merged often. I don’t know if this solution works with mergerfs.

This is what I’ve tried to do without success

user@A ❯ cat /etc/fstab

This is what I was using, which is working fine.

You can probably use GlusterFS for that use case.

I did this in both computers

  1. Change the permissions
❯ sudo chown $USER:$USER /mnt/storage &
❯ chmod -R ugo+rw /mnt/storage &
  1. Set the setgid bit, so that files/folder under <directory> will be created with the same group as <directory>
❯ chmod g+s /mnt/storage &
  1. 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 &
