Cluster LVM

Installation (Debian Jessie)

install necessary packages:
```
apt-get install clvm cman
```
set locking-type in /etc/lvm/lmv.conf to 3

set no wait time for quorum:

echo "CMAN_QUORUM_TIMEOUT=0" >> /etc/default/cman

create config file /etc/cluster/cluster.conf:

<cluster name="mycluster" config_version="2">
   <clusternodes>
     <clusternode name="10.0.0.23" nodeid="1">
         <fence>
         </fence>
     </clusternode>
     <clusternode name="10.0.0.112" nodeid="2">
         <fence>
         </fence>
     </clusternode>
   </clusternodes>
   <fencedevices>
   </fencedevices>
   <rm>
   </rm>
</cluster>

start cman service and clvm service:
```
service cman start
service clvm start
```

check that nodes are online in cluster:

cman_tool nodes

output should be:
