Hi,

I have a Cluster that was fine and now is "Standalone node - no cluster defined" in the GUI. It seems to operate normal. I have some issues that might be related or not (HA seems to be affected). I have upgraded to the latest "5.3-9" and still have the no cluster defined issue.

"/etc/corosync/corosync.conf" are identical on all systems - and has names and ips correct.

"pvecm status" outputs

Code:

what does 'pvesh get /cluster/config/join --output-format json-pretty' show?

Hi,

It says "hostname lookup 'blade04' failed - failed to get address info for: blade04: Name or service not known"

And Blad04 is down for maintenance. With blade04 on - I still have the same "no cluster" issue.

FIXED. Started the two nodes down for maintenance - upgrade them to 5.3-9 - and then the cluster was fine.

Downed another node without the "Standalone node - no cluster defined" issue earlier.

Hello,
I have the same problem.
Cluster 4 node: 3 node online and 1 node offline.
Virtual Environment 5.3-12 (latest available version).
See screenshots:

Help?
Thank you.

root@bPVE:~# pvesh get /cluster/config/join --output-format json-pretty
hostname lookup 'iPVE' failed - failed to get address info for: iPVE: Name or service not known

This is expected because iPVE is offline.
It should not be a problem. Or yes?

Thank you.

This is expected because iPVE is offline.
this has nothing to do with it being offline, this is an error that host cannot resolve the hostname, which
should always work, regardless if the node is online or not

I thought it was enough to record in corosync.conf:

nodelist {
node {
name: bPVE
nodeid: 1
quorum_votes: 1
ring0_addr: 2a04:4880:0:4::7083
}
node {
name: gPVE
nodeid: 2
quorum_votes: 1
ring0_addr: 2a04:4880:0:4::7088
}
node {
name: iPVE
nodeid: 3
quorum_votes: 1
ring0_addr: 2a04:4880:0:4::708a
}
node {
name: jPVE
nodeid: 4
quorum_votes: 1
ring0_addr: 2a04:4880:0:4::708b
}
}

Or do you need entries in /etc/hosts?

for normal inter cluster communications, the node name needs to be resolvable
