Hi everyone, We use Ceph in Cinder as Block Storage. Firsly, we create a VM with volume (volume create automatically) and we write a data in the VM and take an snapshot after wrote data. Then we write data in main VM again and take second snapshot. But, when we try to rescue instance related main VM with first snapshot, there was an error occured.
