Updated title task on 24th March 2017: I have changed the title to reflect that it contains the data for s2 as it was the initial shard that was checksummed for testing, so we used this ticket for it. The rest of the shards have their own ticket.
In s3 the following servers will be decommissioned (T134476)
db1038 - old master
db1015 - rc
db1044 - temporary master for db1095 (sanitarium2)
Before shutting them down for good, we need to make sure we are not losing any data, so we'd need to run pt-table-checksum on them.
Some modifications might be needed in order to run it safely.
