[Gluster-users] consistency between nodes?

[David Roundy]

Here are gluster peer status on the four nodes.  The fifth peer is my
laptop (10.214.70.62), which I have peer probed, but not done anything else
with.  The other news is that I have (since emailing yesterday) rebooted
most of the nodes, which fixed the "missing files" problem.  Before doing
this, I noticed that not all peers agreed in their peer status.  Shouldn't
peer status of all-connected on one node mean that they are all connected?
