Hello,
I am trying to make a setup of Two-Node HA ( https://pve.proxmox.com/wiki/Two-Nod...bility_Cluster ).
I have 2 identical machines (Dell R720 with idrac7) and I have setup a PVE Cluster with these 2 and a quorum disk via an iscsi target from a third-machine.
Although everything seems to work fine: I can do live migration with no packet loss, if I manually fence a node
or crash it on purpose the VM running on the "broken" node is getting moved to the operational one but I get this in the logs:
I have 2 VMs (100,101) both are CentOS 6 (actually 101 is a clone of 100 ) with which I ran these tests.
The setup consists in a drbd session between the 2 nodes on top of which I run gfs2 ( no lvm involved ). I had a hard time
mounting this resource at startup and my cluster.conf looks like this now:
( all the mess with failoverdomains and 2 services was the only solution I found to use the cluster to mount drbd0 )
So the question is why does the VM get restarted? as I see in rgmanager.log it says it was stopped..
Thank you,
Teodor
