Change Details

Folluwup on T314703 where the consumer side of the updater was misconfigured and caused all deletes to be ignored. Replaying the delete log might be tricky to schedule so we should probably reload the full DB from a fresh dump. Procedure (to be clarified): - depool one wcqs2001 - run the reload script - note the date of the dump and position the offset of the wcqs2001 consumer according to this date - start the updater - wait for the lag to catch up - propage the journal to other nodes using the data-transfer cookbook NOTE: T314703 must be fixed before running this runbook. AC: - All wcqs are reloaded from fresh dumps
