Meeting 11 April 2016, 2pm

Attended: drallen a2brenna ldpaniak


  • Timeline
  • Remaining work
  • Issues to discuss


  • Looking good for wrapping up by the 13th! (or earlier!)

Remaining work

  • Everyone:
    • 103620 - assist with HA mysql.cs maintenance documentation : MySQLHAOperationsManual
      • Daniel's revamped based on the HA Testing contents; needs additional data (eg, decision tree detail; slave recovery detail)
      • from last week: twiki pages start with 'Mysql' - and we should separate pages for ease of finding in emergency (mysql failover) - via twiki 'include' in master document
    • 103621 - wrapup and HA mysql.student.cs (phase two) documented plans

  • Anthony:
    • Questions for Fraser about locations for tools - will resolve by using /usr/local/lib/mysql/bin and close the ticket.
    • crontab - will move to /etc/cron.d/mysql rather than master /etc/crontab.
    • 103619 - set up monitoring of HA mysql.cs - and sub items -
      • status: two checks are written, require Devon's assistance to put into nagios.
        • might do an automated backup checking- if time.
        • also: could run a checker to make sure pt-table-checksum isn't running more than two copies.
      • daniel hasn't followed up on inventory/nagios monitoring being busted- we've never gotten alerts
      • needs testing; needs knowing who receives the alerts- set them to alert-list which includes drallen,fhgunn,ldpaniak,helpdesk,lfolland,dlgawley.
        • perhaps we need a mysql task-group (specifically not all databases).
    • Portscanning currently has port 199 open to the world - SNMP - Anthony wil restrict to nagios.cscf.
  • Daniel: as above.
  • Lori:
    • 103822 - test failover of master/slave/slave asynch HA mysql.cs
      • status: we will leave as-is for now, not failing to 106 - bad timing- exams- perhaps in a week and a half, before new term. Perhaps even once a term? on kernel update? no; Dell 730s reboot after kernel upgrade is faster than 5 minutes.
    • 103617 - benchmark HA mysql.cs
      • can't reproduce Fraser's tests- there are lua scripts missing? See ST 103617... He'll keep working on it; this would be nice to figure out.
      • Lori investigated mysql-standard performance_schema database - believes it probably doesn't have interesting data to look at.
