Hello,
I have setup gluster in replicate type and its working fine.
I am seeing a constant chatting between the hosts for lookup
call and lookup reply. I am trying to understand as to why this
traffic is being initiated constantly. Please look at the
attached image. This traffic is using around 200KB/s of constant
bandwidth and is exhausting our allocated monthly bandwidth on
our 2 VPS.
Self-heal-daemon tries to check if there is anything that needs
healing every 10 minutes. Those RPCs are lookups. Could you check
from the tcpdump if it is generating from self-heal-daemon? Which
version of gluster are you using? I think there is a way to increase
this 'time' in latest versions.
