Good day KarthiK.P.R
Other than the replication settings in '/etc/mysql/conf.d/replication.cnf' and our
xyz-web02:/data# cat /etc/mysql/conf.d/custom.cnf
bind-address = 0.0.0.0
datadir = /data
The original /etc/mysql/my.cnf is untouched.
The only other service we have running is DRBD (active / active) and apache, nothing is
hitting apache as this is the standby node.
And there is no load, or anything consuming resources.
