[Gluster-users] Can glusterd be restarted running on all nodes at once while clients are mounted?

[Jeevan Patnaik]

Ah..I am able to differentiate the hosts which are commonly rejected.

It's the hosts that aren't serving any bricks. Is it a bad idea to keep a
host that's not serving any bricks in pool? Don't they in sync with the
other hosts? Regarding my previous assumption that all nodes shoudo be
restarted ate once, I guess it's okay.

Now, I just have to understand the issue with the tiering. Logs are not
helping.

Jeevan.
