I have a question about lvm2 cluster, The scene is that I try to imitate FCSAN by mapping a rbd volume to two compute node, Then I using the rbd volume to create a PV and VG.I stoped the lvmetad daemon on the compute nodes. Then I find that when I operating the VG on one compute node, the changes can also be aware on another compute nodes. But this docment(http://www.tldp.org/HOWTO/LVM-HOWTO/sharinglvm1.html) says that "*LVM is not cluster aware".* My question is that can I use the method to achieve the case that I create or delete lv on one node whlie other compute node can using the lvs? Can anybody explain this? thx very much!
