'Authentication Error' after configuring Cloning groups

Hello,

We have many clusters using ClusterXL and we'll like to use cloning groups to synchronize some features among cluster members. We have configured it using instructions from the Gaia R80.10 admin guide With exactly the same configuration, it works for some clusters but not for others. For those where it doesn't work, we have an 'Authentication Error' message (see enclosed). I've searched the support website but there's nothing pertinent there.

Do you guys have an idea of what could be the problem ?

Thanks in advance for your help.

Kind regards,

Alain

Re: 'Authentication Error' after configuring Cloning groups

Hi, referring this admin guide; did you validate that communication through tcp/1129 are allowed on clusters for which you have this error? For such clusters, did you check status of ClusterXL?

Re: 'Authentication Error' after configuring Cloning groups

Hi Xavier,

Thanks a lot Xavier for your input. The cloning groups are configured for clusters members were ClusterXL is already activated and the status of all our clusters is OK. I can see in the logs that traffic on port TCP/1129 is correctly allowed between different clusters members. It's quite difficult to troubleshoot as we don't have specific logs related to cloning groups. Were can I look for further information regarding this 'Authentication Error' ?

Regards,

Alain

Re: 'Authentication Error' after configuring Cloning groups

So, try How to debug cloning group issues

Waiting that, maybe try to delete the cloning group by removing all the members from it and re-create it (refer to sk109734 "Error writing to remote server: Could not write data to the socket " error from one member of a Clo...).

Re: 'Authentication Error' after configuring Cloning groups

Again, thank you for your support.

  • sk119496 will be needed when we open a TAC ticket. We'll do that after we finish the upgrade to R80.10.
  • sk109734  is for R77.30 and we're running R80.10. We tried it anyway but it didn't help.
  • In sk109734, we have a reference to sk105717 but I cannot access it because I my CCSE certificate is more than 2 years old (see below). Can you send me this sk as PDF ? My email address : alainikaz@hotmail.com.

Thanks !

Alain

Re: 'Authentication Error' after configuring Cloning groups

Done!

BTW, maybe executing sk119496 will already give you a clear idea of the reason?

Re: 'Authentication Error' after configuring Cloning groups

Thanks a lot Xavier for the PDF. Unfortunately, it's not relevant for us. I've tried sk119496 and in the files /var/log/cloningd.log and /var/log/messages, I see the error message "Unable to establish secure connection with x.x.x.x due to Password mismatch". I have this message even if I use very simple passwords on both members of the cluster. Any idea ?

Regards,

Alain

Re: 'Authentication Error' after configuring Cloning groups

One scenario where I had this issue was when "Host Access" was configured throuhg GAIA Portal and don't included the Sync interfaces on the list. Make sure you're not blocking the communication between the members because of this.

Re: 'Authentication Error' after configuring Cloning groups

I don't know if this issue ever got resolved, but I just upgraded a cluster from R77.30 to R80.10 and starting having the same issue. I was seeing 'Authentication Error' logging repeatedly in SYSLOG. I tried to leaving the cloning group and re-joining to no avail. It seemed like the only solution I could come up with was to destroy the entire cloning group, create a new one, and re-join all the members.

I don't know if this is some kind of bug or not? But those steps seemed to resolve it for me.

Re: 'Authentication Error' after configuring Cloning groups

It seems in case of upgrade from lower version, it breaks the Cloning Group and has to be recreated. Happened to me on every cluster I used Connectivity Upgrade. However, this is not listed as known limitation.
