[SOLVED] Remove node from cluster

[starnetwork]

Hi,
I have removed node from cluster before the node was shutdown
now, when I check from another node I see:
# pvecm status
Votequorum information
----------------------
Expected votes: 5
Highest expected: 5
Total votes: 4
Quorum: 3
Flags: Quorate

but I have only 4 nodes in the cluster
how can I update the
Expected votes: 5
Highest expected: 5
to 4 nodes so it's will show the real Expected and Highest Expected nodes?

Regards,

Hi,
it seems that the node was not removed correctly. Is it still visible in the 'pvecm nodes' output?
Here is the relevant section of the documentation: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_remove_a_cluster_node

Make sure the node is powered off before removal!

Hi,
it's already removed from the cluster
in pvecm nodes
I see only the 4 nodes
but sill
Expected votes: 5
Highest expected: 5

suggestion how can I fix it?
should I add back this server to cluster and remove it again?
another solution?

Regards,

Try to set the value to 4 via 'pvecm expected 4'

 

[starnetwork]

we did and it's work
nothing else required?

You still can check your nodelist in /etc/pve/corosync.conf but you should be fine

 

[Chris]

Ah I forgot, also check the nodelist in /etc/pve/.members

I have just experienced this with 6.2-11 on a two node cluster. Posting here because it appears to be highly relevant even if necro posting.

A new two node cluster for testing, removing second node from cluster as per instructions at https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_remove_a_cluster_node

# pvecm nodes

Membership information

    Nodeid      Votes Name
         1          1 test1 (local)
         2          1 test2

# pvecm delnode 2
cluster not ready - no quorum?

# pvecm expected 1
# pvecm delnode 2
error during cfs-locked 'file-corosync_conf' operation: Node/IP: 2 is not a known host of the cluster.

# pvecm nodes

test2 is still present in /etc/pve/corosync.conf, /etc/pve/.members, web gui and pvesh get /nodes

I am facing a strange issue.

After removing 1 node [1] from the cluster=

1) pvcmnodes = Result is OK
2) pvecm status = Result is OK

But,

If I login to web UI, it still shows server3 in the list.
How to remove it?
I don't see the entry of the removed server in = 1) /etc/pve/corosync.conf 2) /etc/pve/.members

How to fix it?
Pls suggest thank you.

Regards,
Amey.

[1] only node which was promox 7.x version, remaining 2 are on proxmox 6.3-2

I'm having the same problem, an old removed node is not present in the cli (`pvecm nodes` for example) but still listed in the GUI....

Hi,

Maybe you already found the answer for the GUI issue, but this worked for me.

On one of the servers still on the cluster go to the folder: /etc/pve/nodes

There you should see a folder with the name of the node you've removed from the cluster. Delete the folder and all the content in it. Then, restart corosync with: systemctl restart corosync
