Hi all,
i'm testing a new proxmox VE 3.0 cluster with 2 nodes and 2 SAN ( openfiler iscsi). Each node is connected to every san with a 10Gbe with a crosslink configuration ( all is connected to all)
Node 1 Node 2
eth1 eth2 eth1 eth2

My goal is to build a full fault tolerant cluster.
I see too many cluster SAN-based with only 1 SAN ( what is the sense to build a super expensive 100 node cluster with one single point-of-failure ??), and i want to build a real-time fault-tolerant storage system.
In red-hat system you can simply configure a raid1 mirror with LVM. cmirror is a cluster component that sync DLM ( distribuite lock manager ) over network to sync raid metadata over cluster nodes.
Unfortunatelly proxmox seem not have this component (i cannot undestand why, proxmox is a red-hat cluster derived and i found all red-hat component except cmirror ). With LVM raid you can use proxmox full features with web gui, create VM, migration, etc...
Now i search some other solutions. I see RDB but if i understand well i have to build a separate cluster for RBD with is for me a crazy solution...
My object is to have a real-time replication storage in a fault tolerant cluster, what i mean is the possibility to turn off a san or unplug connection cables without any downtime ( obv timeout apart ), whitch is the one i can do with cmirror in red-hat cluster.
I'll be very happy if some proxmox developers can integrate cmirror in a future release, but for the moment anyone have a good suggestion for me ?
