How reproducible:

  Every time


Steps to Reproduce:

  1. Implement the following logrotate config

     /etc/logrotate.d/tcmu-runner

     /var/log/tcmu-runner*.log {
       rotate 7
       size 10M
       compress
       missingok
       notifempty
       nodateext
       postrotate
         /usr/bin/killall -HUP tcmu-runner > /dev/null 2>&1 || true
       endscript
     }

  2. When the command /usr/bin/killall -HUP tcmu-runner > /dev/null 2>&1 || true is run manually for testing, both tcmu-runner and gluster-blockd services stop
 

Actual results:

  tcmu-runner and gluster-blockd services terminate


Expected results:

  tcmu-runner should respond properly to the HUP signal and allow the log to be rotated
