Re: Issue when upgrading from 3.6 to 3.7

["B.K.Raghuram" <bkrram@xxxxxxxxx>]

Atin,

Couple of quick questions about the upgrade and in general about the meaning of some of the parameters in the glusterd dir..

- I dont see the quota-version in the volume info file post upgrade, so did the upgrade not go through properly?

- What does the op-version in the volume info file mean? Does this have any corelation with the cluster op-version? Does it change with an upgrade?

- A more basic question - should all peer probes always be done from the same node or can they be done from any node that is already in the cluster? The reason I ask is when I tried to do what was said in http://gluster-documentations.readthedocs.io/en/latest/Administrator%20Guide/Resolving%20Peer%20Rejected/ the initial cluster was initiated from node A with 5 other peers. Then post upgrade, node B which was in the cluster got a peer rejected. So I deleted all the files except glusterd.info and then did a peer probe of A from B. Then when I ran a peer status on A, it only showed one node, B. Should I have probed B from A instead?

I am suspecting it to be new quota-version introduced in the volume info file which may have resulted in a checksum mismatch resulting into peer rejection. But we can confirm it from log files and respective info file content.

Unfortunately, the setup is at a customer's place which is not remotely accessible. Will try and get it by early next week. But could it just be a mismatch of the /var/lib/glusterd files?

Glusterd logs from all the nodes please?

When we upgrade some nodes from 3.6.1 to 3.7.13, some of the nodes give a peer status of "peer rejected" while some dont. Is there a reason for this discrepency and will the steps mentioned in http://gluster-documentations.readthedocs.io/en/latest/Administrator%20Guide/Resolving%20Peer%20Rejected/ work for this as well?

Just out of curiosity, why the line "Try the whole procedure a couple more times if it doesn't work right away." in the link above?
