    XMLWordPrintable

Details

    • Incident report
    • Status: Confirmed
    • Trivial
    • Resolution: Unresolved
    • 5.2.6
    • None
    • Agent2 plugin (N)
    • RHEL 8

    Description

      Steps to reproduce:

      1. Deploy and configure zabbix-agent2 on RHEL8
      2. Import the latest template for smart monitoring from git
      3. Create sudo rule for zabbix user and smartctl
      4. Have disk discovery failing

      Result:

      When trying to run the discovery manually with the agent:

      zabbix_agent2 -v -t smart.disk.discovery

       

      (...)
      2021/04/29 12:47:40.125137 [Smart] stopped looking for RAID devices of megaraid type, err:%!(EXTRA *errors.errorString=failed to get disk data from smartctl: Smartctl open device: /dev/bus/0 [megaraid_disk_00] failed: INQUIRY failed)

      NOTE: smartctl uses and outputs that virtual bus device that does not really exist in the filesystem, but this way you are able to return the smart status:
