DANGER: You are about to delete extent trees from file systems or LUNs. Before performing this operation, note the following:
1. Only the extent trees automatically constructed after the system upgrade can be deleted.
2. After the extent trees are deleted, the space extent consistency check fails.
3. After the extent trees are deleted, the maximum number of consistency point rollbacks changes to 5.
4. The deletion is implemented in the background. The execution duration is affected by workloads and data volumes. You can run the query command to query whether the deletion is complete.
Suggestion: Before performing this operation, ensure that the extent trees need to be deleted from the file systems or LUNs.
