Doc Text:	.New support for earmarking subvolumes Previously, the Ceph storage system did not support a mixed protocol being used within the same subvolume. Attempting to use a mixed protocol could lead to data corruption. With this enhancement, subvolumes have protocol isolation. The isolation prevents data integrity issues and reduces the complexity of managing multi-protocol environments, such as SMB and NFS.	Story Points:	---

Description avan 2024-09-16 12:25:37 UTC

This bug was initially created as a copy of Bug #2312545

I am copying this bug because: 



Purpose:
- To prevent data corruption and ensure protocol compatibility, subvolumes and subvolume groups must be restricted to a single protocol scope—either NFS-ganesha or SMB. Currently, our system does not support mixed protocol use within the same subvolume or subvolume group, and attempting to do so could lead to data corruption.

Solution:
- Implemented earmarking functionality for subvolumes and subvolume groups upon creation, ensuring that they do not share the same subvolume or subvolume group to avoid data corruption due to unsupported mixed protocol use.
    Added commands to set get/set/rm earmark from a given subvolume / subvolume group
