[Linux-cluster] Cluster aware software raid



Hi,

we are trying to use GFS in a FC environment on a two node cluster. 
Additionally to multipathing (performed by IBM's SDD) we want to mirror 
the data on two SAN storages via any kind of raid software. 

As far as I understood, there is currently no software available for linux 
(except Veritas VM) which is able to support this scenario.
I read that CLVM will probably support cluster aware mirroring in the 
future. Are there any estimations, when it will be production ready ?
Will it be released with RH ES 4 ?

In some news groups I saw older postings discussing how to make md cluster 
aware. But, afaik, this also did not happen yet. 
Do you know any other project, which is near to finishing this feature ?

Thanks for your help,
