Cluster in inconsistent state

[Murasakiiru]

Hello,

I create a PVE cluster with 4 servers that works well since 1-2 months.

Since today, I can't create VM anymore (I cannot chose the node)

[[[ screenshot that I can't post ]]]]


I really don't know where to start investigate, my pve cluster seems to be OK in this screen :


[[[[ datacenter summary : the cluster health icon is green, cluster is OK ]]]]]


But not in this one :

[[[[ datacenter cluster : in cluster information i got "Standalone node - no cluster defined"
but I can see in cluster nodenames all my nodes. ]]]]]



So what can I do ? Restart some services ? Re-create the cluster ??

Someone can give me some advices ?


Thanks !!

Hi,

please check the following command on the shell on all nodes.
It should be the same on all nodes.

pvecm status

I found a solution yesterday but I'm surprised :

The node field in my VM creation wizard was empty because a node was dead and not completely removed. But I did not seen it in "pvecm status" :

0x00000002 1 10.142.222.4
0x00000003 1 10.142.222.7

(the dead node was 10.142.222.9)

So I did pvecm delnode pve9-cluster and my cluster returned to his normal condition.

I am surprised that the cluster stop working with just one dead node on a 5 nodes cluster ??
And why in the GUI I had one menu that said the cluster is OK and another one cluster is not ?

By the way the problem is solved.
