RHV-H 4.0: Various log files growing continuously because crond is not running

Issue

• Various log files that use the log rotation facility are not being rotated, and as a result are growing continously, with the potential of filling up the file system.

• Such log files are;

  - /var/log/vdsm/vdsm.log
  - /var/log/vdsm/supervdsm.log
  - /var/log/vdsm/mom.log
  - /var/log/messages
  - /var/log/secure
