I have partitions mounted as shown below and would like to change the label from 'backup' to something more appropriate.
I have only a single shared folder which I'm prepared to delete
1. The web interface on this and other mounts is greyed out,which does not allow unmounting.
2. the delete button on the shared folder is similarly greyed out
Assuming these issues can be resolved is renaming a label as simple as unmounting,, changing the label, and remounting
