Hello

I have a 4 node cluster.

One is a 'cold spare' I do not usually leave it on line.

However I learned that it should be on line when I add a node.

It was powered off when I added a node yesterday.

After powering on today, it is not part of the cluster.

some debugging:
Code:
# journalctl -xn

Dec 14 18:42:22 s020 pmxcfs[8087]: [status] crit: cpg_initialize failed: 2
Code:
# pvecm nodes
Cannot initialize CMAP service
any suggestions to fix this?



thanks, Rob Fantini

PS: It may be that it is impossible to do anything but reinstall. In which case the info would be nice to see as a warning before adding a new node.
that makes for complicated code i think. so a wiki page section for this would be good.

more info

corosync.conf
Code:
quorum {
  provider: corosync_votequorum
}

totem {
  cluster_name: cluster-v4
  config_version: 37
  ip_version: ipv4
  secauth: on
  version: 2
  interface {
  bindnetaddr: 10.1.10.181
  ringnumber: 0
  }

}
and from a working node:
Code:
quorum {
  provider: corosync_votequorum
}

totem {
  cluster_name: cluster-v4
  config_version: 38
  ip_version: ipv4
  secauth: on
  version: 2
  interface {
  bindnetaddr: 10.1.10.181
  ringnumber: 0
  }

}

I hope those are only snippets of your cosorsync config and not the whole one ;)

what does "journalctl -b -u corosync" say?

replacing the outdated corosync config with the current one and restarting the corosync service should resync the cluster

I am unable to mount /etc/pve in local mode - in order to copy the files. /etc/pve is mounted read only.

these days, how do I mount /etc/pve local mode? the old way does not work:
Code:
/usr/bin/pmxcfs -l
[main] notice: unable to aquire pmxcfs lock - trying again

[main] crit: unable to aquire pmxcfs lock: Resource temporarily unavailable
[main] notice: exit proxmox configuration filesystem (-1)

this is how:
Code:
systemctl stop pve-cluster
/usr/bin/pmxcfs -l
[main] notice: forcing local mode (althought corosync.conf exists)

I tried copying corosync.conf from other healthy node to /etc/corosync/corosync.conf and it worked. I mean, it synced and fixed the problem above. Is this recommended way to fix this kind of problem?

other than avoiding that problem by not adding nodes to unhealthy clusters, yes ;)
