[Gluster-users] multiple peer entries in pool list

Hi,

we're seeing multiple entries for nodes in pool list & peer status, each associated with a unique UUID.
Filesystem seems to be working, but we need to clean this up in anticipation of any future issues.

The nodes with multiple UUIDs were previously disconnected, but they're good now.

Does anyone know what's going on & how we can resolve this issue?

thanks,
-john c.
