hello digimer,
I am happy to tell you that I got the reason why I can not access the LVs
on the compute1 node.
Because I make a mistake with thc /etc/lvm/lvm.con on the compute1 node.
Now it works.
Then I would to study how to snapshotting a LV.
Thank you!

It is the resource configration whthin my pacemaker cluster:
[root@controller ~]# cibadmin --query --scope resources
Thank you very much.
Because I am new to pacemaker, and I have checked the docs that additional
devices are needed when configing stonith, but now I does not have it in my
environment.
I will see how to config it afterward.
Now I want to know how the cluster LVM works. Thank you for your patienc

I'm not sure what "cinder" is, so I don't know what it needs to work.

Digimer, thank you very much!
I do not need to have the data accessible on both nodes at once. I want to
use the clvm+pacemaker+corosync in OpenStack Cinder.
then only a VM need access the LV at once. But the Cinder service which
runs on the controller node is responsible for snapshotting the LV

Do you really need to have the data accessible on both nodes at once? To
do this requires a cluster file system as well, like gfs2. These all
require cluster locking (DLM) wh
Thanks for your replay, This snapshot factor will seriously affect my
application.
then, because now I have not a stonith device and I want to verify the
basic process of snapshot a clustered LV.
I have a more question:
After I create a VG: cinder-volumes on controller node, I can see it

I'm experiencing a strange issue with pacemaker. It is unable to check the

Hello Everybody,
