Currently, `GetVolumeGroup()` fetches the RBD group from the pool using the clusterID & poolID encoded in the VolumeGroupHandle. However, this approach may fail in a secondary mirrored cluster, where the clusterID & poolID could differ. This commit ensures that `GetVolumeGroup` leverages the clusterIDMapping and RBDPoolIDMapping to locate the RBD group in the appropriate pool if it is not found in the pool corresponding to the poolID encoded in the VolumeGroupHandle.

you need to make use of the following function instead of singular pool not found check ?
