Hi all, We upgraded to gluster 11.1 and the OP version was fixed in this version, so I changed the OP version to 110000. Now we have some obscure, vague problem. Our users usually run 100+ processes with GNU parallel and now the execution time have increased close to the double. I can see that there are a couple of heals happening every now and then but this do not seem starange to me. Just to make sure that it was not on the client side, I downgraded glusterfs-client to 10 but we still have this slow down. I tried to lower the OP version back to 10 again but this is apparently not possible: volume set: failed: Required op-version (100000) should not be equal or lower than current cluster op-version (110000). Before the change to OP version 11 everything worked fine. Is there a way to "manually" change the OP version back? Or any other ideas on how to fix this? Many thanks in advance!!

Hi Marcus, If you see heals happening, you have to check if all clients are connected to all bricks of the volume. I have seen sporadic healing happening when a client was disconnected from a brick. You can?t lower the OP version and if you are indeed having issues, try to setup NFS?Ganesha as a solution. Best Regards,Strahil Nikolov?
