We had on Saturday the case that a virtual Machine could not be started in a proxmox 2.1 cluster of 3 Machines. We debugged and it looked like the vm image on an nfs server was blocked by another proxmox host in the cluster. It looked a bit as if a migration failed and vncproxy was running on proxmox a while the vm was running on server Proxmox b.

In the task list we saw continous "qemu-img info" processes running against the nfs image so that the vm was locked.

Finally the only way we found to solve the problem was to reboot all proxmox servers.

Does somebody have an ides what might have happened ? Is there a way to delete all open tasks in a proxmox cluster ? Are there tools and documentation for proxmox task management ?
 
No, the NFS server was ok.
After rebooting all Proxmox hosts the Machine could startup again.
The Problem looked like a "wild proxmox task that did never finish", maybe the task of starting vncproxy for that vm
My question is: How can I manage proxmox tasks, e.g. delete all running tasks in proxmox.
