Ceph » RADOS

We have enabled a stretch-cluster configuration on a pre-production system with several already existing and used pools.

After a series of tests we realized this configuration is not suitable for our case. I can't find a way how to fully roll-back CEPH to its original state.
I can roll-back MON epoch and get rid of stretch-cluster mode, but cannot revert OSDmap epoch due to large amount of changes made and OSD epoch versions expiration.
