Symptoms

Impact:
  • User unable to log in using the UI from the browser
  • Unable to use SANnav
  • Linux host file system full
Environment:
  • DELL software: Dell Connectrix SANnav 2.2.1
  • DELL software: Dell Connectrix SANnav 2.2.2
  • DELL software: Dell Connectrix SANnav 2.2.2.1
  • DELL software: Dell Connectrix SANnav 2.2.2a
Issue:
The file system filling up on the SANnav server is preventing the user from logging in.
  • Application Messages are displayed in the EVENT logs (Fault => Events)
    • SMP-SMON-1001: Disk is 70% full (INFO)
    • SSMP-SMON-1002: Disk is 80% full (WARNING)
    • SSMP-SMON-1003: Disk is 90% full (CRITICAL)
(The possibility is available to configure an event action policy to receive an email when these events occur to minimize the risk of missing the events.)
  • The script "check-sannav-status.sh" indicates that all services are down.
Specific requirements:
This issue is only reported when Gen7 switches are discovered.
  • Dell Hardware: Connectrix ED-DCX7-4B
  • Dell Hardware: Connectrix ED-DCX7-8B
  • Dell Hardware: Connectrix DS-7730B
  • Dell Hardware: Connectrix DS-7720B

Cause

SANnav collects flow metrics from the switches and stores the metrics in temp files for further processing. The temp files are supposed to be deleted after processing the data.

An issue in the code prevents the files from being deleted. As this continues, the file system fills up.

As this issue only manifests with GEN7 switches in the environment, disk usage depends on the number of GEN7 switches and chassis managed in SANnav.
