Sync error on Cluster node

[Falconbase]

Hi all,

i have a PMG-Node the have after a crash syncing error, but works fine:

daemon.log:
Aug 21 11:02:45 mx-in-01 pmgmirror[4425]: starting cluster syncronization
Aug 21 11:02:45 mx-in-01 pmgmirror[4425]: sync error: syncing master configuration from '1.2.3.4' failed: rsync error: error in rsync protocol data stream (code 12) at io.c(235) [Receiver=3.1.2]

* do you have a cluster? and is the master really on '1.2.3.4'? (or did you modify the ip address?)
* please post the contents of '/etc/pmg/cluster.conf' (anonymized - remove the keys)

Hi,

i replaced the ip-adress in this post only, cutted the /etc/pmg/cluster.conf-file Node 5 (node-in-3) has the failure

master: 1
        fingerprint 32:EB:D3:08:0D:B2
        hostrsapubkey AAAAB3NzaC1yc2EA
        ip 1.2.3.4
        maxcid 5
        name node-1

Hmm - please restart `pmgtunnel` and `pmgmirror` (on the node with the problem)
* does `journalctl` show any relevant lines on node 5 or master?

 

[Falconbase]

i found the problem hostkey mismatch on the rsync command in pmgmirror, but not via ssh??

 

[Stoiko Ivanov]

hmm - how do you connect via ssh?
from the config-file you pasted - does something like: `ssh -l root -o BatchMode=yes -o HostKeyAlias=node-1 1.2.3.4` work when run on Node 5)?

Hi Stoiko,

the Problem is resolved. I restore a older VM-Image of the PMG.
