clouddb1013

DB section s1 (alias: mysql.s1) DB section s3 (alias: mysql.s3)

so for s3, the other hosts are:

puppet $ grep s3 hieradata/hosts/clouddb10*.yaml hieradata/hosts/clouddb1013.yaml: s3: 100G hieradata/hosts/clouddb1017.yaml: s3: 100G hieradata/hosts/clouddb1021.yaml: s3: 40G

but is there something different about 1021? 

node /^clouddb10(13|14|15|16)\.eqiad\.wmnet$/ {
   role(wmcs::db::wikireplicas::web_multiinstance)
}

node /^clouddb10(17|18|19|20)\.eqiad\.wmnet$/ {
   role(wmcs::db::wikireplicas::analytics_multiinstance)
}

node 'clouddb1021.eqiad.wmnet' {
   role(wmcs::db::wikireplicas::dedicated::analytics_multiinstance)
}

In the aliases I see: 

db-wikireplica: P{O:wmcs::db::wikireplicas::web_multiinstance or O:wmcs::db::wikireplicas::analytics_multiinstance or O:wmcs::db::wikireplicas::dedicated::analytics_multiinstance}

So they all work together. But I think I'll ignore 1021 for now.

So I need 1017 to be applied for

OK FORGET ALL THAT

1014 has s2 and s7

puppet $ cat hieradata/hosts/clouddb1014.yaml

  1. clouddb1014

profile::wmcs::db::wikireplicas::mariadb_multiinstance::instances: 

 s2: 95G
 s7: 185G
