ha-Questions in pve4

[MasterTH]

Hi,

i installed two nodes with proxmox 4 for testing the new features and prepare myself to migrate the older clusters to the new version. So i'm currently trying to break the cluster.

one thing i faced is that a lxc was in an error-state. i didn't know what i can do and deleted it. This was not good i know, i should be able to bring the vm back from the error-state. (Log file: "service ct:100 is not running and in an error state")
The question is, in proxmox 2 and 3 we got the rgmanager and it's clusvcadm to disable a pvevm:xxx and reenable it when the vm is not booted because of an error state. Whats the tool in pve4?
What can cause a vm to be in error-state?
What can i do when a vm is in this state?

I tried to migrate the lxc from one to another host (disk stored on nfs), it failed. Then i rebooted the server where the vm was running to force the migration


kind regards

Hi, I have the same problem, I ve forgot to detach local CDROM from VM and it originated errors in a HA migration test with proxmox 4. Now the VM is in a error state and I cant find a way to clear that state. The VM no longer starts. Please someone how to clear VM error states in PVE4? Luis Miguel

Hi,

what to do in an error state is documented in the ha-manager man page:
$ man ha-manager

ERROR RECOVERY
       If after all tries the service state could not be recovered it gets placed in an error state. In this
       state the service won't get touched by the HA stack anymore.  To recover from this state you should
       follow these steps:

       ·   bring the resource back into an safe and consistent state (e.g: killing its process)

       ·   disable the ha resource to place it in an stopped state

       ·   fix the error which led to this failures

       ·   after you fixed all errors you may enable the service again

So simply disable the resource to place it in an stopped state.

I updated the PVE 4 HA wiki entry also, as it seems that people look rather there than in man pages (both should be used ).

Sorry to update this old post,
But I have a very similar problem, but it keeps coming back without any reason.
One of my VMs goes to HA error state, I don't know why, then I disable it from HA and adding it again, it gets fixed.
But everything will happen again day after.
How can I find the cause of this weird behavior ?
