Hi there,

i have a strange problem with the above mentioned kernel. I'm running a cluster with 3 machines. 2 of them work fine, but the 3rd one is giving me continous errors in the syslog:

This error starts at the moment i've installed this kernel. Proxmox installation works, but cluster configuration not.

It seems that the fuse mounted /etc/pve is not working anymore after "pvecm add" .....

Does anybody seen this error before?

Hi,
What kernel do you install? Is it a pve-installation or on top on squeeze?

Please post the output of "pveversion -v".

Udo
This is a squeeze system with an pve kernel.

# pveversion -v
pve-manager: 2.0-18 (pve-manager/2.0/16283a5a)

The error show a problem with radeon or DVI ... but this is a server within a Datacenter, there no monitor attached and just a graphic onboard.

Anyway, the proxmox installation is no problem and as a single node it should work fine (even with this error). But as soon as i try to connect this server to the cluster, all data in /etc/pve dissapear and the cluster configuration fails.

The only thing i've found in the log is:


vestatd[6259]: WARNING: ipcc_send_rec failed: Verbindungsaufbau abgelehnt


This server is connected with an internal address to the other nodes. (IP multicast workd fine with the other nodes)


This is the only machine with this trouble....

Hmm,
do you can ssh to the other clusternodes without password?
Show the output of "pvecm status" any hints (compare with the output of the running cluster).

Udo
this is the output on the master:

# pvecm status
Version: 6.2.0
Config Version: 13
Cluster Name: t4hosting
Cluster Id: 50071
Cluster Member: Yes
Cluster Generation: 60

Expected votes: 2
Total votes: 2
Node votes: 1
Quorum: 2

Node name: bazinga-2
Node ID: 1
Multicast addresses: 239.192.195.91
Node addresses: 109.234.106.16


and this on the not working node:

pvecm status

Config Version: 12
Cluster Name: t4hosting
Cluster Id: 50071

Yes, i can do a ssh connect without password.

Hi,
hmm - without quorum no go...
What happens, if you change expected votes to 1 on the non-working node?
( pvecm expected 1)

Udo
The main problem is, that the folder /etc/pve on the not working node looks like this:

/etc/pve# ll
insgesamt 1
-r--r----- 1 root www-data 465 12. Feb 17:43 cluster.conf
lr-xr-x--- 1 root www-data 0 1. Jan 1970 local -> nodes/bazinga
lr-xr-x--- 1 root www-data 0 1. Jan 1970 openvz -> nodes/bazinga/openvz
lr-xr-x--- 1 root www-data 0 1. Jan 1970 qemu-server -> nodes/bazinga/qemu-server


and on th eworking cluster nodes like this:

/etc/pve# ll
insgesamt 4
-rw-r----- 1 root www-data 451 6. Feb 20:11 authkey.pub
-rw-r----- 1 root www-data 415 12. Feb 18:11 cluster.conf
-rw-r----- 1 root www-data 465 12. Feb 18:11 cluster.conf.old
lrwxr-x--- 1 root www-data 0 1. Jan 1970 local -> nodes/bazinga-2

-rw-r----- 1 root www-data 1533 6. Feb 20:11 pve-root-ca.pem
-rw-r----- 1 root www-data 1679 6. Feb 20:11 pve-www.key
lrwxr-x--- 1 root www-data 0 1. Jan 1970 qemu-server -> nodes/bazinga-2/qemu-server
-rw-r----- 1 root www-data 526 9. Feb 12:17 storage.cfg
-rw-r----- 1 root www-data 89 8. Feb 21:49 user.cfg
-rw-r----- 1 root www-data 1473 11. Feb 14:55 vzdump.cron


The not working nodes folder looks ok until i use pvecm add .... after this command it looks like above showed

Hi,
that's normal without quorum! An clustermember without quorum have the /etc/pve-filesystem readonly. If your new node get the quorum (and joined sucessfull) the pve-fs will sync with the right data.

All right, thanks, that's clear now.

I've changed it to expected 1 ... but no changes on the error. I try to restart cman:

That's of course the non working node ......

I guess i know what the problem is.

The master and the first node are within the same rack and connected to the same switch, but this node is within a different rack and connected to a different switch.

All three nodes are connected with eth1 to an own internal switch.

Is it possible, that quorum try's to connect just through eth0 instead of the internal address?

my /etc/hosts looks like this:

127.0.0.1 localhost109.234.106.16 bazinga-2.t4hosting.de bazinga-2


192.168.10.4 leonidas
192.168.10.2 bazinga-2
192.168.10.3 bazinga

but pvecm status shows:
# pvecm status
Version: 6.2.0
Config Version: 17
Cluster Name: t4hosting
Cluster Id: 50071
Cluster Member: Yes
Cluster Generation: 68

Ok, i did it .... it was indeed the IP multicast ....

the problem was, taht the external IP had the same shortcut (bazinga) as the internal ... i've removed the shortcut from the external ... and since then ... it works ...

Thanks for your help udo :)
