Hi,

I used to successfully run a replica 3 gluster volume, but since the last 4.0.5 update, they can't connect each other with the message : gluster [gluster peer status guadalupe1.v100.abes.fr] command failed on server guadalupe2.v100.abes.fr.

So host guadalupe1 can't never be up.

When doing gluster peer probe, they are connected as expected. I reinstalled vdsm and gluster, but it is still the same.

I found this on guadalupe2 supervdsm.log

We can see guadalupe2 can see guadalupe1 but taskset still executes peer probe to guadalupe1 with message "Host guadalupe1.v100.abes.fr port 24007 already in peer list"

How can I say to guadalupe2 stop trying to probe guadalupe1?
