Duplicate shares on file system

Troubleshooting
1

Thanks in advance

I just reinstalled my server last night with the latest download, I haven’t done this in a while so I was bit behind.
anyway now I’m looking on the file system and I’m finding in the /mnt2 folder that I have a set of shares listed and if i cd into my data folder i have the same set of shares listed there as well
I am running version 3.9.121-16 just wondering if this is also my issue with trying to install a rockon

and if I try to remove the duplicate I get not permitted even when logged in as root

[root@rockstor mnt2]# ls -latr

and in creating a new share and trying to delete it Im getting this error

You shares are managed as BTRFS subvolumes.

You have your pool mounted in /mnt2/data
Every share you create on your data pool, is a subvolume of /mnt2/data, meaning that if you create a share called test, it will be available as a directory, /mnt2/data/test.
Subvolumes are also mountable, and Rockstor mounts the shares individually in /mnt2.
This means that you’ll see /mnt2/test and /mnt2/data/test.

The behaviour you’re seeing here is correct. Your data is not duplicated, it just has multiple locations pointing at it.

The python error you’re seeing later I believe is a result of you removing one of the share mounts which Rockstor relies on.

So after some time and a little investigation it looks like the issue was related to the shares not being owned by the right user some were owned by root and some by admin others were by users that were removed upon the upgrade.
After changing some of them to admin I can now remove the shares that I wanted to remove.

So this brings the question as to what should the ownership be for the shares and pools?
