Hi,

I am trying to create a percona server datastore and datastore version. I
have used the below commands.

root at trove:/etc/trove# su -s /bin/bash trove -c "trove-manage
datastore_update percona ''"
Datastore 'percona' updated.
root@ trove :/etc/trove# su -s /bin/sh -c "trove-manage
datastore_version_update percona 5.7 percona
cc2fbce7-4711-49bd-98ae-19e165c7a003 percona 1" trove
Datastore version '5.7' updated.
root@ trove :/etc/trove# su -s /bin/bash trove -c "trove-manage
db_load_datastore_config_parameters percona 5.7
/usr/lib/python3/dist-packages/trove/templates/percona/validation-rules.json"
Loading config parameters for datastore (percona) version (5.7)

I have added percona section in trove.conf

[percona]
tcp_ports = 3306

When I try to deploy a database instance, it gives an error. Digging down
further via ssh to the db instance, I have found below repetitive errors in
agent logs.
