Re: Big problems after update to 9.6

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

Hello,

After verifying that our backup was good we tried upgrading the other server to version 9.6, and then it worked fine. So it appears that version 9.1 and 9.6 couldn't talk to each other.

Is this expected? I had thought that nodes with the same major version number would be able to communicate without problem.

Thanks.

Hi David,

It seems like a network issue to me, As it's unable to connect the other node and getting timeout.

Few things you can check- 
  • Check the /etc/hosts file on both the servers and make sure it has the correct IP of the other node.
  • Are you binding gluster on any specific IP, which is changed after your update.
  • Check if you can access port 24007 from the other host.
If all the above checks are fine then you can try to stop the glusterd on both the nodes(sg first and then br), and make sure there is no gluster related process left, then start gluster on br first and check the `gluster peer status` then start gluster on sg.  ( If you can take the downtime 🙂 )

Thanks,
Anant

Is it possible that version 9.1 and 9.6 can't talk to each other? My understanding was that they should be able to.

We've tried to remove "sg" from the cluster so we can re-install the GlusterFS node on it, but the following command run on "br" also gives a timeout error:

gluster volume remove-brick gvol0 replica 1 sg:/nodirectwritedata/gluster/gvol0 force

How can we tell "br" to just remove "sg" without trying to contact it?

Hello,

We have a cluster with two nodes, "sg" and "br", which were running GlusterFS 9.1, installed via the Ubuntu package manager. We updated the Ubuntu packages on "sg" to version 9.6, and now have big problems. The "br" node is still on version 9.1.

Running "gluster volume status" on either host gives "Error : Request timed out". On "sg" not all processes are running, compared to "br", as below. Restarting the services on "sg" doesn't help. Can anyone advise how we should proceed? This is a production system.
