Thanks a lot! Yes, I did upgrade to 3.7.13 but was unaware of the new cluster op-version. Could this incorrect op-version have been the cause for some of the peers being in the rejected state after an upgrade?
No, even if you run with a older op-version, things should not break. You'd need to bump up the op-version only when you want to use the new features been introduced with the same version.

Apparently, from your config files in the /var/lib/glusterd/glusterd.info the operating-versionis still 30700. We have implemented quota-versioning in 3.7.6 and we have another feature(enhancing quotaenable/disable performance improvements) implemented in 3.7.12.To use these features, you need to bump up the op version after the upgrade by doing'gluster v set all cluster.op-version 30712(In case of 3.7.12). I guess this would fix the problem you reported.Let us know otherwise. If this does not fix the issue, please revert us back with the logs.--Regards,Manikandan Selvaganesh.On Wed, Jul 27, 2016 at 10:51 AM, Manikandan Selvaganesh <mselvaga@xxxxxxxxxx> wrote:Hi Ram,Apologies.

We've tried a couple of times to upgrade from 3.6.1 and the vol info files never seems to get a quota-version flag in it.. One of our installations is stuck at the old version because of potential upgrade issues to 3.7.13.On Mon, Jul 25, 2016 at 6:40 PM, Manikandan Selvaganesh <mselvaga@xxxxxxxxxx> wrote:Hi,
It would work fine with the upgraded setup on a fresh install. And yes, if quota-version is not present it would cause malfunctioning such as checksum issue, peer rejection and quota would not work properly. This quota-version is introduced recently which adds suffix to the quota related extended attributes.

Will it cause the quota functionality to malfunction?Manikandan,We just overwrote the setup with a fresh install and there I see the quota-version in the volume info file. For the upgraded setup, I only have the /var/lib/glusterd, which I'm attaching. Once we recreate this, I'll send you the rest of the info.On Mon, Jul 25, 2016 at 5:41 PM, Manikandan Selvaganesh <mselvaga@xxxxxxxxxx> wrote:Hi,Could you please attach the vol files, log files and the output of gluster v info?On Mon, Jul 25, 2016 at 5:35 PM, Atin Mukherjee <amukherj@xxxxxxxxxx> wrote:_______________________________________________On Mon, Jul 25, 2016 at 4:37 PM, B.K.Raghuram <bkrram@xxxxxxxxx> wrote: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?If you are seeing a check sum issue you'd need to copy the same volume info file to that node where the checksum went wrong and then restart glusterd service.And yes, this looks like a bug in quota. @Mani - time to chip in :)
- 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?volume's op-version is different. This is basically used in checking client's compatibility and it shouldn't change with an upgrade AFAIK and remember from the code.
- 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?peer probe can be done from any node in the trusted storage pool. So that's really not the issue. Ensure you keep all your peer file contents through out the same (/var/lib/glusterd/peers) where as only self uuid differs and then restarting glusterd service should solve the problem.On Sat, Jul 23, 2016 at 10:48 AM, Atin Mukherjee <amukherj@xxxxxxxxxx> wrote: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.

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?
