mhddfs + chown

  • So I am still using mhddfs (gonna look into unionfs) and was checking out my file permissions. During that process I noticed that I was able to chown any file/directory as non-privileged user to i.e. root:users and vice versa for shares under the mhddfs path (i.e. /media/mhddfs_guid).


    Is this an added "bonus" of using mhddfs?


    To be clear, a file owned by "root:users" under a share exported by mhddfs could be changed to be owned by "my_username:users" and vice versa. Verified with a clean OMV install.

    mhddfs is a fuse filesystem and it runs in userspace. The fstab entry might not be created properly. I would switch to the unionfs plugin and use mergerfs instead of mhddfs.

  • Ok, thanks, gonna look into it. Just thought I'd mention it although users worried about security probably would not be using mhddfs in the first place.

    Here is one reason to use mergerfs...

    I rsync my main server to my backup server which has a mergerfs pool with direct_io flag set. :) CPU in backup server is only a J1900 celeron.
