Hello All,

 

I think to try using LVM2 in my clusters servers and have some questions
about it. Something I got on google, but something not:

 

1. Cluster-LVM is stable for production in Red Hat 5.1?

 

2. In my storage, when I create new LUN (two or more for performance)
and create the new VG with LUNs as PV, the new VG it's visible for each
node simultaneously? I can create three LV and mount one LV in one node,
and mount two LVs in other node for this VG?

 

3. If I need quorum disk (for 3 nodes cluster), I can use a LV for the
quorum disk?

 

4. The LV mount occurs without any "know issue" in the node when the
other node dies?

 

5. The node shutdown dismount all LVs and the cluster can mount
perfectly de LVs in other node?

 

6. I can use the pv, vg and lv operations like an unclustered LVM2
system?

 

Cheers,
