[Linux-cluster] CLVM, GFS and GNBD scenarios?

[andremachado]

Hello,
there are gnbd flaws (at specific versions, verify) and clvm2 limitations.
Read carefully [0].
It seems that recent cvs commits were addressing these problems, but i am not sure, nor tested yet. Verify.
CLVM2 currently does not have a working mirroring feature in cluster mode nor snapshoting.
RH does not recomend gnbd internal fencing in failover [1].
Regards.
