Release: Enterprise Chef 11.2.1

Enterprise Chef 11.2.1 is a critical bug-fix release for customers who installed Enterprise Chef 11.2.0. It corrects a single defect experienced by customers who upgraded from earlier releases.

Bug Fixes:

  • Fixes an issue where private-chef was being changed to private\_chef unexectedly in upstart/runit configuration files

Notes:

If you upgrade from an earlier release of EC, your servers may now have two runit processes configured in upstart

  1. /etc/init/private-chef-runsvdir.conf
  2. /etc/init/private\_chef-runsvdir.conf

The second one is incorrect, introduced by the aforementioned issue in EC 11.2.0. In this condition, you will see two runsvdir processes running with many errors:

ps:

root       924     1  0 05:20 ?        00:00:00 runsvdir -P /opt/opscode/service log: /lock: temporary failure runsv oc_id: fatal: unable to lock supervise/lock: temporary failure runsv couchdb: fatal: unable to lock supervise/lock: temporary failure runsv bookshelf: fatal: unable to lock supervise/lock: temporary failure runsv postgresql: fatal: unable to lock supervise/lock: temporary failure runsv opscode-certificate: fatal: unable to lock supervise/lock: temporary failure

pstree:

Correcting the error:

HA

  1. on both the active/bootstrap and standby backend: remove the errant runsvdir config file
    [code]root@backend1# rm -f /etc/init/private\_chef-runsvdir.conf
    root@backend2# rm -f /etc/init/private\_chef-runsvdir.conf
    [/code]
  2. On the standby (non-bootstrap) backend: reboot your server to clear all remaining orphaned processes and to restart runsvdir to a working state

    root@backend2# init 6

  3. On the standby backend: Verify that there is only a single runsvdir process and it is error-free (all dots)
    root@backend2# ps -ef |grep 'runsvdir -P /opt/opscode/service'
    root       921     1  0 05:35 ?        00:00:00 runsvdir -P /opt/opscode/service log: ...........................................................................................................................................................................................................................................................................................................................................................................................................

  4. on the active/bootstrap backend: trigger a failover and then reboot

    root@backend1# init 6

  6. On the active (non-bootstrap) backend, trigger another failover back to the bootstrap backend
    root@backend2# private-chef-ctl restart keepalived
  7. Test your now-active bootstrap backend to ensure full functionality (note: you may need to point your api_fqdn address at localhost using the server’s /etc/hosts file

  8. On your frontends, follow the Standalone procedure as detailed below
  9. Upgrade following the normal procedure to Enterprise Chef 11.2.1

Standalone

  1. stop the errant runsvdir process:
    # initctl status private\_chef-runsvdir
    private\_chef-runsvdir start/running, process 926
     
     # initctl stop private\_chef-runsvdir
    private\_chef-runsvdir stop/waiting
    
  2. remove the errant runsvdir config file
    # rm -f /etc/init/private\_chef-runsvdir.conf
    
  3. stop all private-chef services
    # private-chef-ctl stop
    
  4. reboot your server to clear all remaining orphaned processes and to restart runsvdir to a working state.
  5. Verify that there is only a single runsvdir process and it is error-free (all dots)
    # ps -ef |grep 'runsvdir -P /opt/opscode/service'
    root       921     1  0 05:35 ?        00:00:00 runsvdir -P /opt/opscode/service log: ...........................................................................................................................................................................................................................................................................................................................................................................................................
