In board 2500 look at the date of the file
5be8603b-18d0-4333-8590-38f918a22857 (marked in bold). Not sure how did you
end up having this file in such time stamp. I am guessing this could be
because of the set up been not cleaned properly at the time of
re-installation.

Here is the steps what I'd recommend for now:

1. rename 26ae19a6-b58f-446a-b079-411d4ee57450 to
5be8603b-18d0-4333-8590-38f918a22857, you should have only one entry in the
peers folder in board 2500.
2. Bring down both glusterd instances
3. Bring back one by one

And then restart glusterd to see if the issue persists.
