As there is no usecase currently, blocking the creation of ROX clone from the ROX volume. Signed-off-by: Madhu Rajanna <[email protected]>
Add support to create RWX clone from the ROX clone, in ceph no subvolume clone is created when ROX clone is created from a snapshot just a internal ref counter is added. This PR allows creating a RWX clone from a ROX clone which allows users to create RW copy of PVC where cephcsi will identify the snapshot created for the ROX volume and creates a subvolume from the CephFS snapshot. updates: ceph#3603 Signed-off-by: Madhu Rajanna <[email protected]>
added an e2e test case to create RWX clone from ROX and also try to write extra data in the RWX cloned PVC. Signed-off-by: Madhu Rajanna <[email protected]>
