Question about LVM over iSCSI LUN

[ghusson]

Hello,

I am asking if PVE has an admin fencing mechanism in order to avoid LVM table manipulation on two nodes at the same time ?

Reading this : http://www.tldp.org/HOWTO/html_single/LVM-HOWTO/
section : "LVM is not cluster aware"

I am sharing a PV/VG over iSCSI LUN (untick "use directly" in storage adding process) between three test nodes, with one LV per guest. I am wondering if it is all right or if I should use a LUN by guest ?

Thank you,
G. HUSSON

All pve tools use correct cluster wide locking.
