Hi Pranith,
I'm using this guide
https://github.com/nixpanic/glusterdocs/blob/f6d48dc17f2cb6ee4680e372520ec3358641b2bc/Upgrade-Guide/upgrade_to_3.8.md
Definitely my fault, but I think that is better to specify somewhere
that restarting the service is not enough simply because in many other
case, with other services, is sufficient.
Now I'm restarting every brick process (and waiting for the heal to
complete), this is fixing my problem.
Many thanks for the help.
Greetings,
Paolo
