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.

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!!
Best regards
Marcus
