Complementary information....

After running this:

/etc/init.d/cman stop
/etc/init.d/cman start
/etc/init.d/rgmanager stop
/etc/init.d/rgmanager start
/etc/init.d/pve-cluster stop
/etc/init.d/pve-cluster start
/etc/init.d/pveproxy stop
/etc/init.d/pveproxy start

My cluster get on-line, but the more weird issue is here:

                                                       starting

I remove such VM, 100... It doesn't exist anymore.... But stiil there,

Seconds after, I run clustat again and got this message:
