This happened again today, but this time when the disk was not full on the machine that stopped serving pg_basebackup
requests.

I restarted the problematic stolon-keeper

I have the same issue. Slaves can't sync with basebackup. Master logs:

In my situation master fixed using restart sentinels and remove slave keepers. For followers, remove keeper, restart sentinels and pg_resetwal fixed problem.
What happened
Today we had a production outage of a 11 minutes, suspectedly because:
pg_basebackup
requests from follower nodes.The downtime lasted only 11 minutes because I manually restarted the master
stolon-keeper
that stopped servingpg_basebackup
requests.I observed the following in our 3-node Stolon cluster composed of nodes
node-4
,node-5
,node-6
:node-5
temporarily ran out of disk space while being stolon master.node-5
master, by runningpg_basebackup
.node-5
.pg_basebackup
, and restarting them did not help.pg_basebackup: initiating base backup, waiting for checkpoint to complete
pg_basebackup
responses after the full-disk event, even though disk space was freed up.Write...()
functions:What you expected to happen
Stolon should serve
pg_basebackup
responses when the disk is no longer full.How to reproduce it (as minimally and precisely as possible)
I have not yet tried to reproduce it exactly, as I am not sure how to trigger the other 2 nodes trying to do
pg_basebackup
at the correct time.Logs
