[ClusterLabs] Q: LVM-activate: "WARNING: You are recommended to activate one LV at a time or use exclusive activation mode."

[Ulrich Windl]

Hi!

I configured a shared LVM activation as per instructions (I hope) in SLES15 SP2. However I get this warning:
LVM-activate(prm_testVG_activate)[57281]: WARNING: You are recommended to activate one LV at a time or use exclusive activation mode.

The configuration is:
primitive prm_testVG_activate LVM-activate \
        params vgname=testVG vg_access_mode=lvmlockd activation_mode=shared ...

And I cloned the primitive. So whare is the problem?

Does it mean I have to use parameter "lvname"? If so, dows it mean that step 3 of "PROCEDURE 22.4: CREATING AN LVM-ACTIVATE RESOURCE" is missing the parameter, too?

Example given is:
root # crm configure primitive vg1 ocf:heartbeat:LVM-activate \
params vgname=vg1 vg_access_mode=lvmlockd activation_mode=shared \
op start timeout=90s interval=0 \
op stop timeout=90s interval=0 \
op monitor interval=30s timeout=90s
