Yes, both Linux HA and the (alas, proprietary) OES Novell Clustering
Services do support EVMS in cluster mode. The later one for up to 32
nodes, I'm told.

Wrong way to look at this I think, Linux HA is user-space only and thus
of course doesn't include a CFS, same as OpenAIS. They ain't aiming at
providing a full stack on their own.
Using OCFSv2 with Linux HA would address this, for example.
