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 12:17:49 UTC

Purpose:
- To prevent data corruption and ensure protocol compatibility, subvolumes  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 and attempting to do so could lead to data corruption.

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