We have a small glusterFS environment, when we setup this, and run
gluster peer probe,
some nodes are shown as host name, while others are showing IP address,
in our deployment environment, we have DSN setup, so every host name can
be correctly resolved to IP address,
but still strange that some host shown as host name, while others shown
as IP address,
Terminology:
probing node - node that initiates the probe operation
probed node - node that is being added to the cluster
gluster peer probe is an unidirectional operation. When a new node is
probed with its hostname, the probing node knows about the hostname of
the probed node and adds that to its database. However the probed node
gets to see only the probing node's IP address from the network
connection. Hence it records only the IP address in its database. To
overwrite IP address with hostname, another peer probe operation with
hostname of the probing node can be done from the probed node.
