Hi, my Name ist Heinz and i´m really newbie.  
First of all i try to set up a Open Nebula CLuster with Ceph as datastore.

**Open Nebula Cluster**  
1 Frontend called **Nebula01** (HP DL 360 G6)  
3 Nodes called **Cnode01, Cnode02, Cnode03** (2 x HP DL 360 G8 , 1 x DL 360 G6)

**Ceph Cluster**  
1 x Admin, Deploy Node called **Cephmon01** (HP DL 360 G6)  
3 x Mon Nodes called **Cephnode01, Cephnode02, Cephnode03** (HP DL 360 G6)

## Open Nebula configured Basic based on the Quick Start Dokumentation [https://docs.opennebula.org/5.4/deployment/open\_cloud\_storage\_setup/ceph\_ds.html](https://docs.opennebula.org/5.4/deployment/open_cloud_storage_setup/ceph_ds.html)

And now my problems:

i tried to verifiy my Opennebula Installation with 3.4.1 KVM Based Cloud Verification  
i imported the TTYLinux Template on the defoult configuerd datastore (not Ceph)…but don´t wont start with error:

- deploy\_action, error getting driver kv
- New LCM state is BOOT\_FAILURE

2nd. Problem:  
my Ceph Datastore isn´t correct configured, it shows 0 Space

It´s a desaster for a newbie like me.  
Please help…Team Viewer Session it´s also a solution. 🤣
