Hi all I'm experiencing sporadic errors when starting CTs having their FS on a ploop device. The thing is I can't reproduce the error when starting the CTs manually, I only get them when the cluster managment (pacemaker) starts them.
The setup is a 3-node (hostnodes) cluster with pacemaker controlling the CTs and their resources. The CT's ploop devices are hosted an NFS share mounted on all nodes. I am not sure there is something wrong with OpenVZ. I suspect more something along the lines of the cluster starting the CTs too early, before the NFS mount is fully ready or something. First, I thought the error means that the root directory is not accessible/not existing at start time. I changed the start script so that it will only try to start the CT after making sure the CT's root directory is accessible. However, I still get the errors sporadically. Altough, it might not be an OpenVZ problem, the community still might be help identify the issue. What does below error exactly mean?
