[Gluster-users] set: failed: Quorum not met. Volume operation not allowed. SUCCESS

[Karthik Subrahmanya]

Hi,

You had server-quorum enabled which could be the cause of the errors
you were getting at the first place. In latest releases only
client-quorum is enabled and the server-quorum is disabled by default.
Yes, the order matters in such cases.

Regards,
Karthik
